Mounting Installation Damage
1. When dismounting the drive which is mounted on the system
while power is supplied to it.
• The drive to be dismounted must be separated from the
loop. Dismounting the drive which is not separated from
the loop may cause an unexpected error.
• If the drive is not separated from the loop, issue an LPB to
the drive from the initiator in a primitive sequence of the
order set.
• It is recommended to stop the spindle motor prior to this
loop separation operation. The spindle motor can be
stopped by a START/STOP command. It takes about 30
seconds for the spindle motor to stop completely.
• Then, dismount the drive using the drive
mounting/dismounting mechanism, etc. of the system. If
the drive is dismounted while the spindle motor is running,
special care is required to avoid excessive vibration or
shock to the drive. It is recommended to stop the operation
once the SCA connector breaks off contact and wait until
the spindle motor stops (about 30 seconds) before dismount
the drive.
• When storing or transporting the drive, put it in an
antistatic bag. (Shown in Section 5.1).

2. When dismounting the drive which is mounted on the system
while power is not supplied to it.
• Do not move the drive until the drive stops completely
(about 30 seconds if the spindle motor was stopped by a
START/STOP UNIT command, and about 30 seconds after
powering-off when the power was simply turned off).
• Then, dismount the drive using the drive
mounting/dismounting mechanism, etc. of the system.
• When storing or transporting the drive, put it in an
antistatic bag. (Shown in Section 5.1).
Data loss
When the SEND DIAGNOSTIC command terminates with the
CHECK CONDITION status, the INIT must collect the error
information using the REQUEST SENSE command. The RECEIVE
DIAGNOSTIC RESULTS command cannot read out the error
information detected in the self-diagnostics.
