I made a mistake today and deleted a file with almost 1 GB (RAR) that I believed to be uploaded to a server. It was not, due to a server error.
After that I downloaded at least 4 or 5 different softwares to at least tell me if the file could be recovered. It was deleted using Shift + Del (today) and nothing was written on that directory ever since. I even restarted the computer (Win XP SP3). This was done on C: on a 750 GB Hard Drive, using Truecrypt and Whole-disk-encryption, and 5-6 GB free (HDD needs to be cleaned and I am currently uploading files for that purpose).
However, I noticed one thing. All of those programs that claim to recover deleted files (some are irrecoverable) never detects recently deleted files. I was able to find small (not so recent) files, and a lot others with different sizes, that were deleted months and even years ago.
But none of those programs were capable of finding recently deleted files. Which means, I will need to write more data on the Hard-Drive and make them irrecoverable as well because for some unknown reason Windows is not informing those programs that data was purged on such areas.
Is there a reason for that? Something I am not aware of?
I thought it was possible to recover (or at least see a status about the deleted file) right after that file was gone. Looks like I was wrong.
Note: A list of some programs tested for this: Magic Uneraser 2.0 / Recuva.
