-
- PROBLEM : A customer has an Adaptec 1542 controller with a CDC 630MB
- drive and CDC 650MB drive, using the Adaptec VADD that was tested and approved
- by Novell. When the drive gets 5MB or less space free, they get an error
- "Warning: Fatal dir error on volume XXX FAT sector 1". They have to reboot the
- file server before anyone can login.
-
- SOLUTION : Some of the large SCSI drives like the CDC drives vary
- in the amount of cylinders and heads that are actually on the drive.
- Therefore, the drive type may not match correctly. When NetWare gets out to
- the end of the drive it cannot access the sectors that, in actuality, are not
- there even though they were defined in the drive setup by the VADD. This
- problem occurs most often when the customer mixes and matches controllers with
- drives. When buying a controller and drive from the same manufacturer these
- incompatibilities are usually fixed.
-
- There are two solutions to try. 1) Get the correct drive type information from
- the drive manufacturer and install it. 2) Backup the drive, re-intialize it,
- and define a smaller NetWare partition. That way, NetWare will not attempt to
- access the drive beyond the maximum limit.
