General Description
STEC’s MACH2 CompactFlash (CF) card is an extremely high-performance,
multi-channel solution available in capacities from 128MB to 16GB using SLC
NAND flash. The standard CompactFlash interface provides designers with a
true plug-n-play storage device, allowing for short design cycles and fast time
to market, while the extreme performance enables hard disk drive
performance in a much smaller and more reliable design.
CompactFlash cards have quickly become the product of choice for
applications requiring high reliability and high tolerance to shock, vibration,
humidity, altitude, and temperature. Because the MACH2 CompactFlash uses
NAND flash technology (e.g. no moving parts), it is more reliable and has
much lower latency compared to a traditional hard disk drive and consumes far
less power (approximately 1 watt compared to 12 watts for a standard
7200rpm ATA disk drive). With its small footprint, high capacity, and rugged
design, the MACH2 CompactFlash is an ideal hard disk drive replacement or
alternate storage solution in space-constrained applications or those requiring
less capacity than available hard disk drives offer including blade servers and
embedded PCs.
STEC’s MACH2 CF Card is available in a CompactFlash Type I package and
adheres to the latest industry compliance and regulatory standards including
UL, FCC, RoHS, and the Compact Flash Association (CFA). Because the
MACH2 CF incorporates a proprietary state-of-the-art flash memory controller,
it provides the greatest flexibility to customer-specific applications while
supporting key flash management features resulting in the industry’s highest
reliability and endurance. Key features include:
Full datapath protection with built-in 8-bit BCH ECC engine to detect and
correct up to 8-bit errors per 512 Bytes of data
Sophisticated bad block management and wear leveling algorithms
dramatically enhance flash memory endurance
Power-down data protection ensures data integrity in case of power loss
Lifecycle management feature allows users to monitor the card's lifetime by
monitoring the card's remaining spare blocks
STEC’s MACH2 CF card offers the highest reliability and tolerance to shock,
vibration, humidity, altitude, ESD, and temperature. The rugged industrial
design combined with temperature testing and adherence to rigid JEDEC
JESD22 standards ensures flawless execution in the harshest environments.
In addition to custom hardware and firmware designs, STEC also offers value-
added services including:
Custom labeling and packaging
Custom software imaging and ID strings
Full BOM control and product change notification
Total supply-chain management to ensure continuity of supply
In-field application engineering to help customers through product design-ins

This is a DMA Acknowledge signal that is asserted by the
host in response to (-)DMARQ to initiate DMA transfers. In
TrueIDE Mode, while DMA operations are not active, the card
shall ignore the (-)DMARQ signal, including a floating
condition. If DMA operation is not supported by a TrueIDE
Mode only host, this signal should be driven high or
connected to VCC by the host. A host that does not support
DMA and implements both PC Card and TrueIDE modes of
operation need not alter the PC Card mode connections

UDMA on card, the host shall keep the –REG signal asserted
during the execution of any DMA Command by the device.

The CF Card does not have a write protect switch; therefore,
this signal is held low after the completion of the reset
initialization sequence.
-IOIS16
(PC Card I/O Mode)
A low signal indicates that a 16 bit or odd byte only operation
can be performed at the addressed port.
-IOCS16
(TrueIDE Mode)
In TrueIDE Mode this output signal is asserted low when this
device is expecting a word data transfer cycle.

-DMARQ
(PC Card Memory Mode:

O
43
This signal is not used in this mode.
This signal is a DMA Request that is used for DMA data
transfers between host and device. It shall be asserted by the
device when it is ready to transfer data to or from the host.
For Multiword DMA transfers, the direction of data transfer is
controlled by -IORD and -IOWR. This signal is used in a
handshake manner with (-)DMACK, i.e., the device shall wait
until the host asserts (-)DMACK before negating (-)DMARQ,
and re-asserting (-)DMARQ if there is more data to transfer.
In PCMCIA I/O Mode, the -DMARQ shall be ignored by the
host while the host is performing an I/O Read cycle to the
device. The host shall not initiate an I/O Read cycle while -
DMARQ is asserted by the device.
In TrueIDE Mode, DMARQ shall not be driven when the
device is not selected in the Drive-Head register.
While a DMA operation is in progress, -CS0 (-CE1)and -CS1
(-CE2) shall be held negated and the width of the transfers
shall be 16 bits.
If there is no hardware support for TrueIDE DMA mode in the
host, this output signal is not used and should not be
connected at the host. In this case, the BIOS must report that
DMA mode is not supported by the host so that device
drivers will not attempt DMA mode operation.
A host that does not support DMA mode and implements
both PC Card and TrueIDE modes of operation need not
alter the PC Card mode connections while in TrueIDE mode
as long as this does not prevent proper operation in any
mode.
-INPACK
(PC Card I/O Mode except
UDMA protocol active)
Input Acknowledge
-DMARQ
(PC Card I/O Mode: UDMA
protocol active)
The Input Acknowledge signal is asserted by the CF Card
when it is selected and responding to an I/O read cycle at the
address that is on the bus. The host uses this signal to
control the enable of any input data buffers between the CF
Card and the host’s CPU.
Same as (-)DMARQ above.
DMARQ
(TrueIDE Mode)
Same as (-)DMARQ above.
BVD1
(PC Card Memory Mode)

This signal is asserted high as since a battery is not used
with this product.
-STSCHG

Status Changed
Asserted low to alert host to changes in READY, Write Protect
states. Use is controlled by Configuration and Status Register.
-PDIAG
(TrueIDE Mode)
In TrueIDE Mode, this input/output signal is the Pass
Diagnostic signal in the Master/Slave handshake protocol.

This signal is not used by the CF Card, and is pulled up to
VCC through a 4.7K ohm resistor.
In all modes, when Ultra DMA mode DMA Write is active, this
signal is asserted by the device during a data burst to
indicate that the device is ready to receive Ultra DMA data
out bursts. The device may negate -DDMARDY to pause an
Ultra DMA transfer.
In all modes, when Ultra DMA mode DMA Read is active, this
signal is the data in strobe generated by the device. Both the
rising and falling edge of DSTROBE cause data to be latched
by the host. The device may stop generating DSTROBE
edges to pause an Ultra DMA data in burst

Notes:
1. All timing measurement switching points (low to high and high to low) shall be taken at 1.5 V.
2. All signal transitions for a timing parameter shall be measured at the connector specified in the measurement
location column. For example, in the case of tRFS, both STROBE and -DMARDY transitions are measured at
the sender connector.
3. The parameter tCYC shall be measured at the recipient’s connector farthest from the sender.
4. The parameter tLI shall be measured at the connector of the sender or recipient that is responding to an
incoming transition from the recipient or sender respectively. Both the incoming signal and the outgoing
response shall be measured at the same connector.
5. The parameter tAZ shall be measured at the connector of the sender or recipient that is driving the bus but must
release the bus to allow for a bus turnaround.

5.0 Host Access Specification
5.1 Task File Register and Byte/Word/Odd-Byte Mode Mappings
Please refer to the CompactFlash standard for complete details on the following items:
Task File Register mapping for the interface modes
Byte/Word/Odd-byte mode mapping within each of the interface modes
5.2 Host Access Interface Modes
The host can access the CF Card by using the following interface modes with the Task Registers:
PC Card Memory Mode, Attribute Memory
The Card Information Structure (CIS) in Attribute Memory can be accessed by Byte/Word/Odd-byte
modes in PC Card Memory Mode. The -REG signal must be asserted when accessing Attribute Memory.
The CF Card is mapped to PC Card Memory Mode by the Index bits in the Configuration Option Register.
An example of a CIS is listed in 5.3, Card Information Structure (CIS).
PC Card Memory Mode, Common Memory
Common Memory can be accessed in the Byte/Word/Odd Byte modes in PC Card Memory Mode. The
-REG signal must be de-asserted when accessing the Common Memory. The CF Card is mapped to PC
Card Memory Mode by the Index bits in the Configuration Option Register
PC Card I/O Mode
The CF Card can be accessed by Byte/Word/Odd Byte modes in PC Card I/O Mode. The CF Card is
mapped to PC Card I/O Mode by the Index bits in the Configuration Option Register. The Index bits also
select Contiguous I/O, Primary I/O, or Secondary I/O mapping when using the PC Card I/O Mode.
True-IDE mode
The CF Card is configured in a TrueIDE Mode of operation when the -ATASEL input signal is asserted
GND by the host at power up. In the TrueIDE Mode, Attribute Registers are not accessible from the host.
The Data Register is accessed in word (16-bit) mode at power up. The CF Card permits 8-bit accesses if
the host issues a Set Feature Command to put the CF Card in 8-bit mode. Parameter information that the
CF Card uses in TrueIDE mode is returned when the Identify Drive command (ECh) is invoked. Refer to
5.4 Identify Drive Parameter for an example.

6.0 Registers
This chapter lists the registers of the CF Card. Refer to CompactFlash standards for further details.
6.1 Configuration Registers
In PC Card Mode, four configuration registers, as listed in Table 28, are used.
Note: In TrueIDE Mode, these registers cannot be used.
Table 28: Configuration Registers
Configuration Register
Description
Configuration Option Register
This register is used to configure and observe the status of the CF
Card, and to issue soft resets to it. Also, the Index bits of this register
are used to select the PC Card mapping mode that the CF Card uses:
1) PC Card Memory, 2) PC Card Contiguous I/O, 3).PC Card Primary
I/O, and 4) PC Card Secondary I/O
Configuration and Status Register
This register is used for observing the CF Card state.
Pin Replacement Register
This register is used for providing the signal state of -IREQ when the
CF Card is configured in the PC Card I/O Mode.
Socket and Copy Register.
This read/write register is used to identify the CF Card from other
devices. This register should be set by the host before this
Configuration Option register is set.

Datasheet
61000-07000-106, May 2011 55
6.2 Task File Registers
Table 29: CF Card Task File Registers
Task File Register
Description
Data Register
The Data Register is a 16-bit read/write register used for transferring data
between the CF Card and the host. This register can be accessed in word
mode and byte mode.
Error Register
The Error Register is a read-only register that is used for analyzing an error.
This register is valid when the BSY bit in the Status register and Alternate
Status register are set to ―0‖ (Ready). Diagnostic Codes are returned in the
Error Register after an EXECUTE DRIVE DIAGNOSTIC command (code 90h).
Extended Error Codes returned in the Error Register after a REQUEST SENSE
command (code 03h).
Sector Count Register
This register contains the numbers of sectors of data requested to be
transferred on a read or write operation between the host and the CF Card. If
the value in the register is 0, a count of 256 sectors is indicated.
Sector Number Register
When the LBA bit in the Drive/Head register is 0, this register contains the
starting sector number for any media access. When the LBA bit is set to 1, this
register contains bits 7:0 of the LBA for any media access.
Cylinder Low Register
In CHS mode (LBA=0), this register contains the low-order bits of the starting
cylinder address. In LBA mode, it contains bits 15:8 of the LBA.
Cylinder High Register
In CHS mode (LBA=0), this register contains the high-order bits of the starting
cylinder address. In LBA mode, it contains bits 23:16 of the LBA.
Drive/Head Register
This register selects the CF Card address translation (CHS or LBA) and
provides head address (CHS) or high-order address bits 27:24 for LBA.
Status Register
This read-only register indicates status of a command execution. When the
BSY bit is ―0‖, the other bits are valid; when the BSY bit is ―1‖, the other bits
are not valid. When the register is read, the interrupt pin is cleared.
Alternate Status Register
This register is the same as the Status register, except that is not negated
when the register is read.
Device Control Register
This write-only register is used for controlling the interrupt request and issuing
an ATA soft reset to the CF Card.
Drive Address Register
This read-only register is used for confirming the CF Card’s status. This
register is provided for compatibility with the AT disk drive interface and it is
not recommended that this register be mapped into the host’s I/O space
because of potential conflicts on bit 7.
Command Register
This write-only register is used for writing the command that executes the CF
Card’s operation. The command code is written in the command register after
its parameters are written in the Task File during the CF Card ready state.

7.0 Supported ATA Commands
The ATA commands used by the CF Card are listed in Table 30. Refer to CompactFlash standards for
details.
Table 30: CF Card Supported ATA Commands
Command Set
Code
Description
CHECK POWER MODE
E5h or 98h
This command checks the power mode.
EXECUTE DRIVE
DIAGNOSTIC
90h
Command performs internal diagnostic tests implemented by
the CF Card. Diagnostic Code is returned in Error Register.
ERASE SECTOR(S)
C0h
Cmd is used to pre-erase/condition data sectors in advance.
FORMAT TRACK
50h
This command writes the desired head and cylinder of the
selected drive with a vender unique data pattern (typically 00h
or FFh). Card accepts a sector buffer of data from the host to
follow the command with the same protocol as the WRITE
SECTOR(S) Command although the information in the buffer
is not used.
IDENTIFY DRIVE
ECh
This command lets the host receive parameter information
from the CF Card in the same protocol as READ SECTOR(S)
command.
IDLE
E3h or 97h
Command causes the CF Card to set BSY, enter the Idle
mode, clear BSY, and generate an interrupt. If the sector
count is non-zero, automatic power down mode is enabled. If
the sector count is zero, the automatic power down mode is
disabled.
IDLE IMMEDIATE
E1h or 95h
This command causes the CF Card to set BSY, enter the Idle
mode, clear BSY, and generate an interrupt.
INITIALIZE DRIVE
PARAMETERS
91h
This command enables the host to set the number of sectors
per track and the number of heads per cylinder.
NOP
00h
No Operation.
READ BUFFER
E4h
Command enables host to read contents of card’s sector
buffer.
READ DMA
C8h
If UDMA is enabled, this command is the sector read
command used for UDMA transfer. If UDMA is not enabled,
this command is the sector read command used for MWDMA
transfer.
READ MULTIPLE
C4h
This command performs similarly to the READ SECTOR(S)
command. Interrupts are not generated on each sector, but on
the transfer of a block which contains the number of sectors
defined by a SET MULTIPLE command.
READ LONG SECTOR
22h or 23h
Command performs similarly to the READ SECTOR(S)
command except that it returns 516 bytes of data instead of
512 bytes.
READ SECTOR(S)
20h (w/ retry)
21h (w/o
retry)
Command reads from 1 to 256 sectors as specified in Sector
Count register. A sector count of 0 requests 256 sectors.
Transfer begins at sector specified in Sector Number register.
SLCFxxxM2TU(I)(-x) CompactFlash Card
Datasheet
61000-07000-106, May 2011 57
Command Set
Code
Description
READ VERIFY
SECTOR(S)
40h (w/ retry)
41h (w/o
retry
This command verifies one or more sectors on the CF Card
by transferring data from the flash media to the data buffer in
the CF Card and verifying that the ECC is correct. This
command is identical to the READ SECTOR(S) command,
except that DRQ is never set and no data is transferred to the
host.
RECALIBRATE
1Xh
The CF Card performs only the interface timing and register
operations. When this command is issued, the CF Card sets
BSY and waits for an appropriate length of time, after which it
clears BSY and issues an interrupt. When this command ends
normally, the CF Card is initialized.
REQUEST SENSE
(EXTENDED ERROR)
03h
Command requests extended error code after command ends
with error. Extended error code is returned in Error Register.
SEEK
7Xh
This command is effectively a NOP command to the CF Card
although it does perform a range check.
SET FEATURES
EFh
Command is used by the host to establish or select features.
SET MULTIPLE MODE
C6h
Command enables card to perform multiple read and write
operations and establishes block count for these commands.
SET SLEEP MODE
E6h or 99h
This is the only command that allows the host to set the CF
Card into Sleep mode. When the CF Card is set to sleep
mode, the CF Card clears the BSY line and issues an
interrupt. The CF Card enters sleep mode and the only
method to make the CF Card active again (back to normal
operation) is by performing a hardware reset or a software
reset.
STAND BY
E2h or 96h
This command sets the CF Card in Standby mode. If the
Sector Count Register is a value other than 0H, an Auto
Power Down is enabled and when the CF Card returns to the
Idle mode, the timer starts a countdown. Time is set in Sector
Count Register.
STAND BY IMMEDIATE
E0h or 94h
This command causes the CF Card to set BSY, enter the
Standby mode, clear BSY and return the interrupt
immediately.
WEAR LEVEL /
SECURITY FREEZE
LOCK
F5h
When Security Command Set is not supported: The command
code is effectively a NOP command and only implemented for
backward compatibility. The Sector Count Register is always
returned with a 00h indicating Wear Level is not needed.
When Security Command Set is supported and Security is
enabled or disabled: The command code invokes the
SECURITY FREEZE LOCK command.
WRITE BUFFER
E8h
This command enables the host to overwrite the contents of
the CF Card’s sector buffer with any data pattern desired.
WRITE DMA
CAh
If UDMA is enabled, this command is the sector write
command used for UDMA transfer. If UDMA is not enabled,
this command is the sector write command used for MWDMA
transfer.

Code
Description
WRITE LONG SECTOR
32h or 33h
This command is provided for compatibility purposes and is
similar to the WRITE SECTOR(S) command except that it
writes 516 bytes instead of 512 bytes.
WRITE MULTIPLE

8.0 Security Mode Feature Set
Note: Part Numbers with -S support the Security Mode feature set.
The Security Mode feature set allows the host to set and use a security password system to prevent
unauthorized CF Card access.
After the initial setting of the User Password, the card enters Lock mode on the next power-up or
hardware reset. When card is in Lock mode the card rejects access commands until a SECURITY
UNLOCK command is invoked.
To prevent accidental or malicious password activation or setting, it is recommended that the host issue a
SECURITY FREEZE LOCK command on initialization. This command places the card in Frozen mode
which disables the following commands until a power off or hardware reset:
Security Set Password
Security Unlock
Security Disable Password
Security Erase Unit
If SECURITY FREEZE LOCK is issued when card is already in Frozen mode, the command executes and
card remains in Frozen mode.
When the passwords are set, the Security Level parameter may be set to High or Maximum. If the User
Password is forgotten, the Master Password can be used to unlock the card only if the Security Level has
been set to High. If the Security Level was set at Maximum and the User Password is forgotten, data on
the card is lost and only a SECURITY ERASE UNIT command can be invoke (along with the Master
Password) to recover use of the card.
During a power up session, the card keeps security count of failed User and Master Password SECRUITY
UNLOCK commands. After 5 failed attempts, the Expire bit 4 of Word 128 in IDENTIFY DRIVE
information is set and SECURITY UNLOCK and SECURITY ERASE UNIT commands are aborted until
power down or hardware reset.
8.1 Security Mode Feature Set Support and Identify Command
When Security Mode feature set is implemented, the IDENTIFY DRIVE Command returns the following
information for Word 128:
Word 128 bit 0 shall be set to ―1‖ to configure the card for Security feature set support.
Word 128 bit 5 shall be cleared to ―0‖ to indicate that Enhanced Security Erase feature set is not supported.
Word 128 bit 1 shall be cleared to ―0‖ at first use turning off (disabling) security in until a SECURITY SET
PASSWORD command is issued by host.
Word 128 bit 2 shall be cleared to ―0‖ at first use to indicate card is not locked until a SECURITY SET
PASSWORD command is issued by host.
Word 128 bit 3 shall be cleared to ―0‖ at power up or hardware reset to indicate card is not frozen. If a SECURITY
FREEZE LOCK is issued when card is already frozen, Word 128 bit 4 shall be set to―1‖ even at power up or
hardware reset to indicate CF card is frozen.
Word 128 bit 4 shall be cleared to ―0‖ at power up or hardware reset to indicate security count is not expired.
Word 128 bit 8 shall be cleared to ―0‖ at first use to indicate a high security level until changed by a SECURITY
SET PASSWORD command.

8.2 Security Commands
Security commands are invoked by writing the command code to the Command Register. Refer to Table
33 for a description of the supported Security Commands.
Table 31: Supported Security Commands
Command
Code
Description
SECURITY DISABLE
PASSWORD
F6
This command requests transfer of single sector of data from host which
contains Control Word 0 (to select Master or User Password compare),
and Password 1-16 (32 Bytes). If password matches password previously
saved by the card, the card disables lock mode. Command does not
change Master password which may be reactivated later by setting a
User password.
SECURITY ERASE
PREPARE
F3
This command shall be issued immediately before SECURITY ERASE
UNIT command to enable device erasing and unlocking. Command
prevents accidental erase of card.
SECURITY ERASE UNIT
F4
This command requests transfer of single sector of data with control and
password. If password is matched, command executes. The SECURITY
ERASE PREPARE command shall be completed immediately prior to this
command.
SECURITY FREEZE LOCK
F5
This command sets the card to Frozen mode in which the following
commands are disabled: 1) Security Set Password, 2) Security Unlock, 3)
Security Disable Password, and 4) Security Erase Unit. Frozen mode is
disabled by power off or hardware reset. If Security Freeze Lock is issued
when card is in Frozen mode, command executes and card remains in
Frozen mode.
SECURITY SET PASSWORD
F1
This command requests transfer of single sector of data with Control and
Passwords. Depending on the content of the Control Word, the User or
Master Password, and the High or Maximum Security Level is set.
SECURITY UNLOCK
F2
This command requests transfer of single sector of data from host. If
identifier bit is set to Master and the device is in high security level, then
the password supplied shall be compared with the stored Master
password. If card is in maximum security level, then the unlock command
shall be rejected. If the identifier bit is set to user, then card compares the
supplied password with the stored User password. If the password
compare fails then card returns command aborted to host and
decrements the unlock counter. Counter is initially set to five and is
decremented for each password mismatch when Security Unlock is
issued and card is locked. Once this counter reaches zero, SECURITY
UNLOCK and SECURITY ERASE UNIT commands are command
aborted until after a power-on reset or a hardware reset is received.
SECURITY UNLOCK commands issued when the device is unlocked
have no effect on the unlock counter.

9.0 Host Protected Area Feature Set
Note: Part Numbers with -S support the Host Protected Area feature set.
The Host Protected Area (HPA) feature set allows data storage outside the normal OS file system when
the card is initially configured.
For example, during initialization the BIOS can obtain full access to the card by issuing a SET MAX
ADDRESS to the card’s native address. The BIOS can read hidden configuration data, and then when
exiting initialization, the BIOS issue another SET MAX ADDRESS command to lower the maximum
address and hide the configuration data from the OS.
The SET MAX ADDRESS command also allows the maximum address to be volatile (card returns to the
last set maximum address after power or hardware reset cycle) or non-volatile, (card retains the set
maximum address after a power or reset cycle).
When the BIOS receives control prior to power down, the BIOS can READ NATIVE MAX ADDRESS, then
issue a volatile SET MAX ADDRESS to the native maximum address. The BIOS can write configuration
data to the HPA. On power down, the maximum address returns to the last non-volatile setting.
9.1 HPA Feature Set Support and Identify Command
When HPA feature set is implemented, the IDENTIFY DRIVE Command returns the following information
for Words 82, 83, 85, and 86:
Word 82 bit 10 shall be set to ―1‖ to configure the card for Host Protected Area feature set support.
Word 85 bit 10 shall be set to ―1‖ to at power on to indicate that Host Protected Area feature set is enabled.
Words 83 and 86 bit 8 shall be cleared to ―0‖ to indicate that SET MAX SECURITY EXT is not supported.
9.2 HPA Commands
HPA command set is invoked by writing the command code to the Command Register. Refer to Table 33
for a description of the supported Security Commands.
Table 32: HPA Commands
Command
Code
Description
READ NATIVE MAX
ADDRESS
F8
This command returns the native maximum address. The native
maximum address is the highest address accepted by the device in the
factory default condition. The native maximum address is the maximum
address that is valid when using the SET MAX ADDRESS command.
SET MAX ADDRESS
F9
After successful command completion, all read and write access attempts
to addresses greater than specified by the successful SET MAX
ADDRESS command shall be rejected with an IDNF error. After a
successful SET MAX ADDRESS command using a new maximum LBA
the content of IDENTIFY DEVICE words (61:60) shall be equal to the new
Maximum LBA + 1. More than one non-volatile SET MAX ADDRESS
command after a power-on or hardware reset will report an IDNF error.

10.0 SMART Feature Set
Note: The following part numbers support the SMART feature set:
Part Numbers without -S (capacities > 2GB)
Part Numbers with -S (all capacities)
Self-Monitoring, Analysis, and Reporting Technology (the SMART feature set) is used to protect the user
from unscheduled downtime. By monitoring and storing critical performance and calibration parameters,
SMART feature set devices attempt to predict the likelihood of near-term degradation or fault condition.
Informing the host system of a negative reliability condition allows the host system to warn the user of the
impending risk of a data loss and advise the user of appropriate action.
10.1 SMART Support and Identify Command
When SMART feature set is implemented, the IDENTIFY DRIVE Command returns the following
information for Words 82, 84, and 85:
Word 82 bit 0 shall be set to ―1‖ to configure the card for SMART feature set support.
Word 84 bit 1 shall be set to ―1‖ to indicate that SMART self test is supported.
Word 84 bit 0 shall be cleared to ―0‖ to indicate that SMART error logging is not supported.
Word 85 bit 0 shall be set to ―1‖ turning on (enabling) the SMART features at plug in until a SMART DISABLE
OPERATIONS command is issued by host.
Word 87 bit 1 shall be set to ―1‖ turning on (enabling) the SMART self test at plug in.
10.2 SMART Commands
