Quantum 10K II 5.38 SEEK (6) Command (0Bh)

SCSI Description
Quantum Atlas 10K II Ultra160/m SCSI Hard Disk Drives 5–199
5.38 SEEK (6) Command (0Bh)
The SEEK (6) command uses a 6-byte Command Descriptor Block to request the
drive to send the drive heads to the requested Logical Block Address. The drive
responds by placing the heads at the correct Logical Block Address. When the heads
are at the specified Logical Block Address, they are not guaranteed to stay in that
position since periodic calibrations may send them to a different cylinder.
