Crashed HFS+ disk recovery?
Allen Ethridge
Can anyone recommend a tool for either fixing a crashed disk or
recovering the files on the disk that works on HFS+?
(Yes, the critical files were backed up, but a lot of not-so-easy
to replace files weren't.)

The only tool I've heard of is Disk First Aid, by Apple. Soon: techtool,
Not so soon: Norton

I have no problem repairing an HFS+ internal HD with Disk First Aid,
starting up from a second internal HD (HFS) under OS 8.1. I received no
message about open files on the HFS+ volume.

Disk First Aid can't repair your startup disk. It can fix HFS+
problems if you boot from another disk (8.1 CD or something). It won't
fix all problems though (at least I don't think it will...DFA was never
that good). I had a few icon problems that it was able to fix with no
problems. I hope Norton comes out soon...

I assume you're starting up from the SyQuest drive as well as running Disk
1st Aid off it.
If the hard disk is screwed up, it may be falsely reporting open files and
refusing to unmount. Disk First Aid needs to unmount the disk to work on
it, so since it's unable to do that by itself, you should try unmounting
it manually by dragging the hard disk to the trash can. The disk icon will
disappear from the desktop, but Disk First Aid should still be able to
find it and hopefully fix it.

As I wrote in my earlier message, Disk First Aid kept reporting that,
since files were open on my Mac's internal hard disk, it could only
verify, not repair, the disk (DFA found nothing to repair, however). It
made no difference whether I started up from (and ran DFA from) a
SyQuest disk or from the OS 8.1 CD-ROM. It didn't matter, either,
whether virtual memory was on or off on the startup disk or on the
internal hard disk. Apple Support tried to help, but couldn't. Now I am
happy to report that rebuilding the desktop on the internal hard disk
seems to have fixed the problem. I had rebuilt the desktop already
several times since installing OS 8.1, so it never occurred to me to do
it again. But, after I installed OS 8.1 (from the CD-ROM) on a second
SyQuest disk and restarted from the internal hard disk, the desktop was
rebuilt (without my permission) on both disks, and the problem was gone.
So, I suppose there is a moral to this story: When all else fails,
rebuild the desktop. Thanks to everyone who offered help.

by booting from the other volume with extensions off.

Well I'm in the same situation. I now have to rebuild my desktop once
a day in order to keep the thing from crashing. That's right every
day. Over the course of a day it slowly starts to die. icons
disappear, folders gone etc. Also system files are no longer
locatable. I then restart rebuild the desktop on all my HFS+
volumes/partitions then I'm functional.
All DFA ever does is say yep there's a problme but I can't do anything
about it.
Thankfully I had the forsight to partion the crap out of my drives.
With a mix of HFS and HFS+ volumes.
I'm desperately waiting on TechTool.
Note I did expect that HFS+ and 8.1 to have disk problems. It's just
way to new not too. I do expect that this version of HFS+ to be modified.
Thus I will have to trash my volumes and reformat etc.
Oh Well.

This is not a typical HFS+ problem. Assuming your hard disk formatting
software is up to date, things should run just fine. However, SCSI chain
conflicts, system extension conflicts, these can add up to trouble. I
updated my desktop Mac and PowerBook to HFS+ weeks ago, and have yet to
see any reports of directory problems.

In lieu of Techtool, you can use Nortons Utilities' Fast Find to
completely obliterate desktop files. Search for "Desktop". FF should
reveal several invisible files. Select the ones named "DesktopDB",
"Desktop DF", and "Desktop". Choose File-->Move-->to trash.
Note: since these are invisible files, the trash will not appear full.
Since they are in use, you will not be able to delete them immediately.
Restart your mac--it will rebuild the desktop files.
Once booting has completed, throw something into the trash--and ampty
folder will do--and then empty it.
