Thx
gregrocker for your reply.
For now, I've installed PCLinuxOS on a partition I made some time ago believing the owner was wanting to update to Win7. So I've yet to actually touch the Vista partition hoping I'm not corrupting it further.
Though I've mentioned that I can see the folder structure and that they are empty - I've since discovered that the folder structure appears to be related to an original install as there are program folders I know I installed - missing and what's worse - user folders I know as the users are also MIA.
So right now I'm not sure what's happened and the 11 year old using this system is not forthcoming. Needless to say, his folks are distraught about possible losing all their personal records including some once only family photos.
I ran testdisk on the partition and it reported that there are no deleted files. That can not be good.
I've put an entry in GRUB for the RECOVERY partition on this HP Pavilion system and am able to access all the recovery tools from that now, ( Changing the partition table some time ago I forgot to update the system enviroment variablies to tell F11 where it was.
Another unhealthy sign is when I copied the whole partition onto a external HDD. I only got 1.14GiB of data.
I can only assume that the kid attempted to hide something ( we've since learned that he took mum's EFT-POS card and brought some Game online - he's just staying quiet about it ) and in doing so caused something to load into ram which was then able to delete everything. If this is not possible then maybe not understanding how to read HPFS - NTFS file structure is my problem - hence I'm holding off the 'Back to factory settings' full re-install.
In the meanwhile I'm coaching them in Linux (KDE) so that they can at least access their email. ( Thank the powers to be that I insisted they remain with IMAP and not POP.)
For now, I'll review your suggestions and otherwise continue to become conversant with the Vista File Structure to be sure I've left no stone unturned.
Any more words of wisdom? Anyone?
