6.4.1 RZ56 Disk Drive Removal
The following section describes the removal and replacement procedures
for the RZ56 and its electronics module. If you have already replaced
the drive’s electronics module and a problem still exists, then you must
replace the whole drive instead of replacing just the electronics module.
