Bet you've never seen this one before:

Running Win2K and have got a copy of PGP that's a couple of years old and was doing some "spring cleaning" -- so ...

HD0 = 80Gb partitioned to 8Gb (C:/) for OS and remainder (D:/) for data.

HD1 = 200Gb partitioned to 30Gb (E:/) for backup files and 160Gb (F:/) for larger storage, video, audio, large images and stuff

Ran chkdsk and defragmented all drives, then began wiping drive free space using PGP. All went OK for the smaller partitions on HD0, but began a wipe on the 160Gb partition and ... oops, now I can't read the data. Hardware is all recognized (I'm pretty sure there is no hardware problem), but when I run Knoppix TESTDISK I'm having difficulty navigating to the problematic drive.

On bootup the hardware and partitions are recognized as hda and hdb -- how do I navigate to the hdb drive to reconstruct the MBR that was no doubt eaten by PGP in the wipe process? This version of PGP probably does not read the large partition and scrambled or deleted the NTFS MBR.

EDIT: Correction
Knoppix reads the drive as [hdb1] and [hdb2], but when I click on the recognized partitions I am told that the device could not be mounted; that "I could not determine the filesystem type, and none was specified."

I tried right clicking on the device and clicked the "mount" option which tells me, again "I could not mount the device"
