After  my  twentieth problem with   connecting/disconnecting SCSI disk
drives, I am   wondering   about  the proper "protocol"  of   handling
connecting/disconnecting/transporting them.

	[1] I understand that first the host should be synced and halted.
	Question: Does the host also need to be powered down, or is the
	ROM Monitor sufficient.

(then)	[2] Should the hard disk be powered down before it is removed
	from the SCSI chain, or can I unplug it from the SCSI chain with
	power on?

(then)	[3] Is it safer to move the hard disk with power on or with power
	off? A repair man once told me that the air pressure from a running
	disk is a better warranty that the head won't touch the disk.

Oh, I own an Imprimis 94601-15 and a Seagate ST41650 disk.
