Dear Experts,
The problem I am describing is similar to this post from August 2011. However, it's not quite the same, therefore I am openining a new thread here.
I have a 1TB hard drive from Western Digital which has three partitions, all of them encrypted with PGP WDE using an RSA public key. This worked fairly well until, one day, the hard drive would not mount anymore. No screen asking for the password would appear. No error message saying that the disk cannot be mounted would appear, either.
It still is somewhat PGP-encrypted, which the following information indicates:
inmbp:~ in$ sudo hexdump -C -n 128 /dev/disk3

00000000 eb 48 90 50 47 50 47 55 41 52 44 00 00 00 00 00 |.H.PGPGUARD.....|

I tried to solve the issue by upgrading to PGP WDE 10.2.0 [Build 1672] but that didn't solve the issue.
The system behaves strangely: It doesn't mount but it also doesn't complain about an unknown file format. The Disk Utility can see the three partitions. PGP Desktop remains silent and doesn't show the drive unless I say "Encrypt" drive (the "Decrypt" option, which is what I would want, doesn't exist). In this case it lists the drive in the menu but fails with the following error messages (log file):

Does any of the experts have any other idea? Otherwise, I will have to live with the (reasonable) data loss and re-format the drive....
Thank you.
