This is complicated to explain but simple in scope. Domain server ruined in Irene flood. On-site person tried to remove domain and set up same profile on a laptop previously joined to the domain. Irreplaceable docuement files in My docuemnts disappeared. I used several Undelete utilities to see if the files could be found. I pulled the drive out and ran it on a desktoip to avoid any more changes. They do not exist anywhere on the hard drive or as deleted files.
I don't expect to get them back, but I'm wondering how that could happen. They are not in a "deleted" state and not existing as real, active files.
I also had the folder backed up on an external drive. I was ordered to delete the particular folder for security purposes. I tried to run some undelete utilities on the external drive and could not find that folder either. Different deep scans would find files with random numbers for file names, but no extensions, so I couldn't tell what they were or who they belonged to. There was no activity on the external hard drive since I deleted the folder in question yet I couldn't find it.
I used Digital Rescue Premium,Advanced Data Recovery, and Recover My Files.
To summarize: Created a new profile that wiped out My Documents, but not pst files in the application data folder of the profile. No evidence of them existing or existing as undeleted files with the folder structure intact. Also I deleted the same folder from an external drive, yet undelete utilities can't find the folder. Why?
