Seagate ST400FX0012, ST100FX0002, ST200FX0002, ST400FX0002 manual Drive Configuration

Page 18

When a region of LBA's are erased via cryptographic erase, as part of the erase, the drive shall unmap those LBAs.

If the host attempts to access an unmapped or trimmed LBA, the drive shall return scrambled data. For a given LBA, the data shall be identical from access to access, until that LBA is either updated with actual data from the host or that LBA is cryptographically erased. The drive shall report a value of '0' in the LBPRZ field returned in the READ CAPACITY (16) parameter data.

If the host attempts to access an unmapped LBA on a drive that has been formatted with Protection Informa- tion (PI), the drive shall return scrambled PI data for that LBA. Depending on the value of the RDPROTECT field in the data-access command CDB, this may result in the drive returning a standard PI error to the host.

If the host reduces the addressable capacity of the drive via a MODE SELECT command, the drive shall unmap or trim any LBA within the inaccessible region of the device.

Additionally, an UNMAP command is not permitted on a locked band.
