I have successfully created a bootable PE cd that can mount PGP Partitions/Drives. This allows for recovery WITHOUT decrypting. A bad block on an encrypted drive is no different. If NTFS becomes corrupted or, heaven forbid, the master file table takes a dump, normally you WOULD have to decrypt first to fix, but not so with a bootable PE cd that can mount the partition. It is business as usual. There is MOST DEFINITIVELY a performance hit when running PGP, but mainly on the CPU. Disk performance itself is not very noticiable (i.e. somewhere between around a -7% in my own experience), but when there is high I/O, whach your system process take off. The filter driver for PGP runs under this process, and there is no doubt about it.
