13.7 Format Unit (F7h: vendor specific)
Table 70: Format Unit command (F7h)
The Format Unit command initializes all user data sectors after merging the reassigned sector location into the
defect information of the device and clearing the reassign information. Both new reassign information and new
defect information are available immediately after the completion of this command. They are also used on the next
power on reset or hard reset. This command erases both previous information data from the device.
Note that the Format Unit command initializes from LBA 0 to Native MAX LBA. Host MAX LBA is set by Initial-
ize Drive Parameter or Set MAX ADDRESS command is ignored. The protected area by Set MAX ADDRESS
command is also initialized.
The Security Erase Prepare command should be completed immediately prior to the Format Unit command. If the
device receives a Format Unit command without a prior Security Erase Prepare command, the device aborts the
Format Unit command.
If the Feature register is NOT 11h, the device returns an Abort error to the host.
This command does not request a data transfer.
