Recover "overwritten" file


Imagine the scenario.

File A is incredibly important so is backed up once a night (or SUPPOSED to be).

New guy comes to company, puts in month old backup disk and copies File A onto it. Except, he doesn't ... he copies the month old file from the backup disk OVER File A...

Ok, they lose a days work, as they can just use the day before backup. Well, if they had been bothered to put in the new disk each night they would have been able to do.... but they didn't, so the month old copy is the earliest.

We have a problem (or rather I don't, but a friend does)

Anyone know of any good version recovery software that can help? Undelete software isn't working so far as the file hasn't been deleted, just a new version overwritten.

Or should I just tell them, they are going to have to rework the month?

Ideas gratefully received!

Try the conventional file recovery softwares, when a file is overwritten, it is not really overwritten on the hard drive.
Your chance of recovering it will be better if you had ample free space when it hits the fan. If the disk was almost full it is virtually impossible to recover the file, even with divine intervention.

Good luck anyways!

Step 1 - Hopefully as soon as the error was discovered the drive was "cloned" with the cloned drive replacing the original, the longer the drive is used the less likely it becomes that anything can be salvaged.

Step 2 - Decide how important the file is, your best bet is professional data recovery, send the original drive to someone like OnTrack or DataSavers, but these solutions are not cheap.

I'm assuming this is not a share on Server2003 with shadow copy enabled (previous versions are easy to recover with shadow copy)

Yes I've already tried that. Though the issue is the conventional software isn't showing older revisions of the file, as far as it's aware, the file is still there (but of course it's the old version) - so there is nothing to undelete....

Nope, shadow copy wasn't on.

Ok, I'll pass the news one. It's a whole month worth of work they have lost, so data recovery might well be worth it. Problem is, they have been using the disk since (this happened yesterday I think)....

Unless someone knows of a great piece of software that might be of use?

PM your email address to me and I will email a program to you that can most likely recover it.

I saw this on The gadget show yesterday

If something is deleted ( even from recycle bin ) its not REALLY deleted.
It can be easily recovered using some recovery tools

Hi, Fulk and Webdude, and anyone else who was offering to send software:
Would this software recover relatively small (around 2mb) files that have been overwritten in the past week? I am in pretty desperate need of something that could do this.

Thanks.

I don't think you have any chance of recovering the file, even if you use professional service.

Deleted files can be retrieved, however, when you overwrite a file, it uses the same address location as the old one instead of creating a new one.

Not sure thou, try consulting a professional service to confirm my theory. I would doubt that file recovery programs will help, they'll just make things worse.

Peace,

Not really. Keep in mind that if a file is deleted, it is also renamed (in windows). It also depend on if deletion went via the recycle bin, which moves it to a different space. However, if he created a file with the same name & size and then deleted it in the same method as the old one.... then I doubt you can recover.

It can be recovered IF something else hasn't already been written over that area of the disk.

As far as the OP's situation, it depends on how the file was overwritten. If the OS allocated new space and wrote the blocks to that space, then the old blocks may still be there. If it updated the blocks in-place, then there's nothing that can be done (except maybe by a couple government intelligence agencies).

i was wondering what programs i could use to try and find it though, instead of just downloading whichever ones pop up at random on a google search. don't know why Webdude had to be secretive about it. i haven't downloaded much if anything to the drive since the overwrite, so i'm thinking there's a chance.
