- Michael, I would not hold out a whole lot of hope that he will get that system
- working solidly. He has 25 wire cables in the system and he has enough drives to
- make the system unusually sensitive to 25 wire cables. Certainly his ZIP drive
- is a toy. The CDROM may also be a toy. (A toy SCSI device is one using 25 wire
- cables and connectors. In that sense the A3000 itself is a toy because some
- <stuff-for-brains> elected to save a little money and space on the back panel.
- At least IT can be fixed by using a good adapter cable that IMMEDIATELY branches
- out to the 25 twisted pairs of a proper SCSI cable.
-
- This may not be his only problem. He *MIGHT* want to get RDPrep and simply read
- and write the RDBs with it. (In fact if the one nasty possibility is a reality
- he should use RDPrepX in these two passes.)
-
- If he uses RDPrepX he should use
- "rdprepx -dscsi.device -q3 -t -u<unit> -s<unit>.device" to create the mountfile.
- If it issues words about 40.4 FFS not being in his L: directory he should get a
- fresh copy of it wherever he acquired it. THen issue the command:
- "rdprepx -dscsi.device -q3 -t -u<unit> -r<unit>.device" to replace fresh RDBs on
- the disks. This will assure that the RDBs are scrubbed clean. (You can get crud
- in there that you do not want. And such crud might well cause the kind of
- problems he is seeing if someone figured out this virus hook.)
