[comp.sys.mac] Mounting a corruped SCSI disk?

syap@cc.rochester.edu (James Fitzwilliam) (05/10/89)

(I am posting this for a friend -- if you can help, thanks much!)

  The short story:  Mass Micro 45 Meg disk cartridge gets corrupted,
Finder sez "This disk is damaged.  Do you want to initialize it?" and
I eject it.  Disk First Aid fixes it once, but before I get a chance
to replace the system on it, more hangs corrupt it again, and now DFA
won't fix it.
  The question:  What did Disk First Aid repair the first time, and
what does it mean when it says "Cannot verify status of disk"?  I am
not worried about losing files; I have utilities to rescue them
anytime.  What I want is to MOUNT THE DISK again, because the
organization of folders, etc. is not backed up.  Can I replace
something by hand to help DFA along?
  Some details:  The boot blocks are probably corrupted, but the
Desktop file is probably intact, or at least very close.  Exactly
what does the "disk is damaged" dialog indicate?  The problem was
likely caused by several SCSI devices being connected, and that can
be avoided in the future.   If anyone knows more than I do about the
information needed to mount a disk, I would appreciate it deeply.  As
a last resort, I could get along with HFS recovery if there were a
way to salvage the *creation dates* of the files.
Thanks in advance, as always.

(Note: It is my understanding that the problem occurred when a disk
operation caused a hang -- for example, screen freezes during file
drag in Finder.  --ed.)

I would like to stress that he is not interested in advice on how to
recover the files.  We can do that already.  If you need to reply via
Email you can address mail to my account and I'll see that he gets it.

If you find out anything interesting, please post it to the net.  I have already
gone through this situation once, where the files can be recovered but not the
HFS folder structure.

Of course, my account will vaporize at the end of finals week, so I may not find
out if anything useful is discovered...
