Hi Frank. I have a problem and you might have some helpful comments to
offer.
I had a serious hard disk failure. Macintosh laptop, IDE drive. Becaue
I'm no newbie, I was able to recover 99% of my data (though it took me
six days). The drive became useless in the process and I have trashed
it.
One file that I transferred over to the new drive I bought is a PGP
disk. Ostensibly, it looks fine but it will not open.
It's not a password problem. I know the passphrase. The virtual disk
itself is corrupted somehow. PGP version 9.06 reports that it cannot
proceed with the "open" request because "it was encrypted with an
unsupported algorithm" (It was, in fact, created by this same copy of
PGP an not all that long ago, either). Double-clicking does not produce
the expected passphrase dialog box but I can still see the disk in the
PGP Open dialog.
DiskWarrior finds no fault with the partition on the new drive that it
is on. TechTool Pro reports the file is ok. Drive Genius says it's ok.
Copying it over to another partition does not make any difference. Data
Rescue cannot help. Interestingly, FileSalvage does not even see the
file.
I can open the data fork with Resourcerer and HexEdit but, as you would
expect, there is no way to ascertain what needs to be edited in order
to repair the file.
The disk does not contan anything illegal so I would have no problem
sending it to a professional firm if I have to. On the other hand, they
are expensive, and the content doesn't really justify a big outlay.
It's just commercially-sensitive data that I can live without, though
inconveniently.
Ideas?
