Shapeshifter and hdd partisions.

[Ilwrath]

I have destroyed my Mac partitions before
because I accidentally moved a bunch
of data over the "limit" without IDEFIX
active...now I am a bit more careful and better
know what I am doing. Sadly Shapeshifter only
works with FFS, so there's not much to stop
something horrible from happening if you
don't have your configurations right.

Hmm?  Am I missing something?
Are we talking about making a dedicated Mac-only (HFS) HD partition, or making an Amiga partition that is used as the root file system directory for Shapeshifter?

I set aside a partition on my system for Shapeshifter used the emulator to format it HFS, and had no problems, whatsoever.  Ran stable and quite fast, compared to directory or hardfile access.  I crashed the Mac out in many nasty ways, and the worst that happened was that one time the MacOS became unbootable, and I had to boot the emulator from my MacOS CD and reinstall.  I never had damage cross out of the partition.  In fact, I don't even have the partition mounted on the Amiga side.

Now, this was on a MUCH smaller hard drive. 150MB Mac partition on a 1.5GB total....  So I never tried it on a drive bigger than the default filesystems could handle.

I disabled IDEFIX and then copied
a bunch of files around above the limit...so
the Mac partitions (using FFS on the amiga side,
also above 4gb) were unfortunately damaged.

Ahh... I see what you're saying, now...  Yeah, that would be a pretty serious problem, eh?

Now as a separate issue, I've had the Mac crash
badly and corrupt the Shapeshifter program
directory on the Amiga side...strange but true!

Actually, thinking about this, I bet I know what happened here.  If the Mac crashes badly on shutdown, an errored PROM file can be written.  I've actually seen this file end up cross-linked with another file in the Shapeshifter directory.  If not quickly fixed, the directory could become corrupt.  If the partition the ShapeShifter directory lives in is PFS, though, this shouldn't happen?  Hmm...
