Table 53 Format Unit Command (F7h)
The Format Unit command initializes all user data sectors after merging 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 right after this command completion, and are
also used on next power on reset. Both previous information are erased from the device by this
command.
Note that the Format Unit command initializes from LBA 0 to Native MAX LBA. Host MAX LBA set
by Initialize Drive Parameter or Set MAX ADDRESS command is ignored. So the protected area by
Set MAX ADDRESS commands 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 Feature register is NOT 11h, the device returns Abort error to the host.
This command does not request to data transfer.
