- A little while ago, there was a discussion here about how to handle
- user files in [SYSLOST]. I've got a somewhat more delicate problem;
- critical system files in [SYSLOST]:
-
- > $ dir/file/own
- >
- > Directory SAIT$DISK:[SYSLOST]
- >
- > 000000.DIR;1 (4,4,2) [SYSTEM]
- > BACKUP.SYS;1 (8,8,2) [SYSTEM]
- > BADBLK.SYS;1 (3,3,2) [SYSTEM]
- > BADLOG.SYS;1 (9,9,2) [SYSTEM]
- > BITMAP.SYS;1 (2,2,2) [SYSTEM]
- > CONTIN.SYS;1 (7,7,2) [SYSTEM]
- > CORIMG.SYS;1 (5,5,2) [SYSTEM]
- > INDEXF.SYS;1 (1,1,2) [SYSTEM]
- > VOLSET.SYS;1 (6,6,2) [SYSTEM]

- Oooo! Wonderfully strange!
-
- (Note that they are on the second member of a volume set). This
- problem came about as a result of an RA81 going sick, leading to:
-
- > Error reading directory [000000]
- > Forced error flagged in last sector read
-
- Makes sense, I guess.... It would be interesting (just in a very general
- way) to know the full sequence of actions that led to this.
-
- The same files (with the same file-ID) appear in [000000] for that
- disk. This situation has continued through an image backup and
- restore.
-
- BACKUP has no reason NOT restore these entries - they are perfectly legitimate
- entries, after all!
-
- Is it safe to SET FILE/REMOVE the entries in [SYSLOST], or
- should I leave well alone?
-
- If I were you, I'd make sure I had a current backup of the disk, the do the
- SET FILE/REMOVE and an immediate ANALYZE/DISK/REPAIR. (It's possible that
- the directory backlinks in the files point to [SYSLOST], not [000000]. The
- ANALYZE/DISK/REPAIR should fix that once you've removed the extra entries.)
-
- Off hand, I can't think of any likely problems from leaving the disk as it
- is, but since these files are basic system files and define the structure of
- the disk, it's probably a good idea to try to get them into their normal
- configuration.
