[comp.sys.mac.programmer] out of memory errors

jtn@potomac.ads.com (John T. Nelson) (12/10/88)

i've run into a problem with my mac II that i am unable to solve.  I
am unable to remove, rename or modify a particular folder on my
desktop.  somehow the file system on this hard disk has become
corrupted.  i'm certain the problem is not the disk drive.

when i do try to perform operations on this folder, the mac claims
that the folder is busy.  worse... i am getting "no more memory"
errors from my jasmine direct tape utility while setting up the dump
parameters.  i cannot rebuild the desktop since doing so also
generates out of memory errors.  i was hoping that rebuilding the
desktop would allow me to remove the wierd folder.

i have 8 meg of memory on my machine by the way, and  140 meg hard
disk.

any suggestions to correcting this problem?

Sometimes the catalog b-tree gets strangely linked and/or has wrong info. This
is common when you are doing some sort of file i/o and the machine crashes. The
other indications are long folder-open times in the finder and i/o errors 
when trying to change thr folder attributes.

As for what you can do, the first thing would be to run Disk First Aid. If
it doesn't detect the error, or can't fix it, do a finder drag of all of the
accessible files on the disk to another volume and re-initialize the disk. The
only way to actually fix a badly linked b-tree other than Disk First Aid that
I know of is FEdit and the HFS chapter... No easy matter!

best of luck.

I would assume you are running under Multi-Finder with a machine
like this.  Under this assumption...

Restart under Finder and try to re-build the desktop.  The Multi-Finder
partition for Finder is large enough for most operations.  One of the 
few operations it is not large enough for is re-building a large
disk.

Good Luck.
