PGP (.pgd) file opens with passphrase, but contents are no longer there.
Posted on 2007-11-20
I have been using a PGP virtual disk for over a year that has grown to over 25GB in size. This file resides on a 1TB RAID-5 array on a system that is protected by redundant APCs and routed through 3 switches to protect it as much as possible from any anomalies such as lightning / surges / blackouts. I do this because I rarely have time to maintain my own stuff. Onto the point - - All has been well until last night, at which point I opened this file using my passphrase (which was cached because I had opened the file the night before), it mounted to drive M: as usual, but there was only a single Word document on M: - None of my folders or files were to be found. Everything had been there the night before, and nothing was shutdown or restarted, nothing automatically updates on my systems, and I am the only person with physical access. My systems all use independent randomly generated passwords that are roughly 20 characters long, so a "hack" is an extremely doubtful probability.
To check the file as much as I knew how, I copied it to an external drive, and then ran a "Compact Unused Space" action on the copy, which did not change its file size at all, leading me to believe there is something there, but for whatever reason, it no longer shows up, no matter which system I use to open the file.
I have spoken with PGP's Tech Support, to which their only answer was "pull from your backup copy" - which is unfortunately 2 months old due to the fact that the system reliability made me feel comfortable to the point of letting backups go to the back burner. The worst part is, is that performing backups more frequently could be a bad thing - Considering the file was working when I used it last, if it had backed up that night automatically, then my backup would have been replaced by this file that magically emptied itself.
So the question is, Has anybody ever experienced this situation, or otherwise know of a solution to the problem? The folks over at PGP cannot explain this and say they have never had this exact problem before, so they were largely unable to help out.
Thanks in advance for any answers that do help! Matt
