7.2.3 Unloadlng a Disc
Before unloading a disc, make sure that the activity indicator is not flashing.
If it is flashing, then the RRD40 is transferring data. Wait intil the indicator
stops flashing.
1. Orient the transparent sleeve for loading. Make sure the arrow is going
into the drive first. Use Figure 7-4 as a guide (the unloading procedure
is the same as the loading procedure).
2. Insert the sleeve into the access door as far as it will go.
3. Remove the caddy. The disc and housing will be back in the sleeve. The
activity indicator will go out.
7.2.4 Disc and Caddy Repairing
The RRD40 media is contained inside a protective caddy. The caddy
consists of three parts: the disc, the clisc housing, and the transparent sleeve
(Figure 7- 5).

the transparent sleeve is damaged or cracked or if the disc needs cleaning,
the caddy can be taken apart.
It is very important that the disc is mounted in the caddy properly. Failure to
mount the disc properly makes the disc inaccessible by the SCSI bus controller.
