ESCRIPTION
READ NATIVE MAX ADDRESS EXT
27h
This command is mandatory for devices that implement the 48-bit HPA feature set and 48-bit
Address feature set. The command will return the native max address; the maximum LBA that is
valid when using the SET MAX ADDRESS EXT command.
READ SECTOR(S)
20h
This command will read from 1 to 256 sectors as specified in the Sector Count Register. A sector
count of 0 (zero) requests 256 sectors. The transfer will begin at the sector specified in the Sector
Number Register.
READ VERIFY SECTOR(S)
40h
This command will verify one or more sectors by transferring data from the flash media to the data
buffer and verifying that the ECC is correct. The command is identical to the Read Sector(s) - 20h
command except that DRQ is never set and no data is transferred to the host.
READ VERIFY SECTOR(S) EXT
42h
This command is mandatory for devices that implement the 48-bit Address feature set. The
command is identical to the Read Sector(s) Extended (24) command, except that no data is
transferred from the device to the host. The device will read the data stored in the media and verify
that no errors exist.
RECALIBRATE
10h
The SSD performs only the interface timing and register operations. When this command is
issued, the SSD 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 SSD is initialized.
SECURITY DISABLE PASSWORD
F6h
This command is mandatory for devices that implement the Security Mode feature set. The
command will transfer 512 bytes of predefined data from the host. If the password selected by
Word 0 matches the password that was previously saved by the device, the device shall disable
Lock mode. The command will not change the Master password. The Master password is
reactivated when a User password is set. The command will only complete successfully if the
device is in Unlocked mode.
SECURITY ERASE PREPARE
F3h
This command is mandatory for devices that implement the Security Mode feature set. The
command is issued immediately before the Security Erase Unit (F4h) command to enable device
erasing and unlocking. The command prevents accidental loss of data on the device.
SECURITY ERASE UNIT
F4h
This command is mandatory for devices that implement the Security Mode feature set. The
command will transfer 512 bytes of predefined data from the host. If the password does not match
the password previously saved by the device, the device shall reject the command and abort it.
When a Normal Erase mode is specified, the Security Erase Unit command shall write binary
zeros to all user data areas. If the optional Enhanced Erase mode is specified, the device shall
write predetermined data patterns to all user data areas; the current data is overwritten, including
sectors that are no longer in use due to reallocation.
