[comp.sys.mac] Diskfit floppy problems?

chuq@plaid.Sun.COM (Chuq Von Rospach) (06/13/88)

Anyone seen this? I just spent a few hours upgrading one of my Mac's with a
bunch of new stuff and made major changes to the System Folder. When I went
in to back up the changes with DiskFit (release 1.4.1) it kept hanging while
trying to load in floppies from the backup set.

Reading/writing floppies at the finder level is no problem. Neither is
reading/writing DiskFit backups under unifinder (which is what I finally did
after half a dozen tries, re-installing Diskfit and System, removing inits,
etc, etc, etc). If I run it under Unifinder, it works. Multifinder, no.

The same revisions of software are all working on the other Mac, with no
problem, of course.

And idea what it might be? A floppy drive going flakey? A corrupted file
somewhere? Bad karma?

What kind of hangs?  I've seen DiskFit get into a (seemingly) endless loop
while accessing the disk.  My only solution is to interrupt the backup, 
start it again, and tell DiskFit that the disk is missing when it gets to
it the second time.  This causes it to format a new disk to replace the 
original. When DiskFit asks for a new disk to format,  I just put the original
disk back in and all is OK.  I've run Disk First Aid on the disks it hangs
with and it reports no problems, so it appears DiskFit is to blame.

Anyone else see this or are Chuq and I the only lucky ones. (The only thing
worse than a bug is an intermittent bug...)

I never run it under Multifinder (I am using release 1.3).  It takes
so much longer, because every time I insert a disk, Finder sees it and
wants to create or read in the Desktop file.  This doesn't happen
under 'uni'finder.  My guess is that DiskFit may be filling certain of
your backup disks just borderline full enough that the desktop file
just doesn't quite fit and something is hanging as a result.  Accept
this as an answer if you have a large grain of salt to go with it.

Chuq,

What version of the System Software are you using?  DiskFit 1.41 (not 1.4.1) is
compatible with System Tools 5.0 and 6.0, running under Finder or MultiFinder.
It could be a possibility that the copy of DiskFit that you are using has
become corrupted and should be replaced with a fresh new copy.  Are you running
out of memory?  If so, check the RAM cache and see if that works.  Other
options are to turn the Fast Copying option off, this will free some memory; as
well as disabling the reporting feature.
