I am wondering if all these other eraser type programs are failing your tests that there must be some sort of backup program running or something.I have tried the most famous erasing software as r-wipe, stellar wipe, and eraser, but in all case Winhex is able to recover some data.
One thing about that approach is that Word leaves temp files (AutoRecovery, shortcuts, what have you) all over the disk. You may have the same file in two places, even after deleting the source. That is potentially where one duplicate came from.binolandia said:eraser version is 5.86.1 installed on Windows XP Professionale SP3
I create 10 new word document with different content and filename and then use your step by step guide fo erase. Take a new snapshot...and i'm still able to recover 2 document (full document readable), 8 was unrecoverable.
Floppy drives exclude the possibility of NTFS compression, yes, I forgot about it. Then there's also the Word/Excel/PowerPoint temporary file in the same folder, it's hidden from view, but I've never checked out what those do. How big are your sample documents?binolandia said:Again here...i think you hate me
test with floppy was unsucessfull:
i'have create 5 .doc and then copy to floppy.
I open the file to make some changes.
I delete all files on floppy
Run Erase Unusued Disk Space (7 pass)
At the end of the process use winhex to recover file by type (doc)
Found 1 doc of 5
If today i have no IT emergency will make test with earlier version of eraser
Yes I understand your idea in principle but just while you are testing with software recovery programs it would speed things up for you to just perform a single pass. A single pass has the same effect on software recovery tools as a multiple pass does.binolandia said:By the way i'm satisfied by multiple pass, is more difficult to recover file !
