Need serious help: Recover lost file after hard disk restore/crash

Had a power failure during a recovery of an Acronis backup on my C: drive. It seems it happened while Acronis just started loading the backup files? When I restarted the Samsung Laptop local drive C: did not appear in Explorer. Only drive D: and my DVD drive E: appeared (C an D are partitions on the same hard disk). The recovery software was on a hidden partition but when trying to use the Samsung Recovery facility it say Drive C: not found.

After trying out suggestions found on the internet I only managed to screw everything up resulting in also loosing the D: drive containing my Acronis backup. The laptop did not start at all. I at last managed to get it going after installing Windows 7 again and I then sit with only C System Disk, D System reserved and E: DVD drive at that point.

Foolishly I shrinked the system disk C and created a data disk. That disk is now Data Disk F. and not D as original.

The Acronis backup containing all my files and data was on the original Data Disk D:

I desperately need to recover that .tib file to get all my documents, data et back.

I have used various free software to try and find that specific file. But they all search by drive and the missing file must be somewhere on the disk either as lost or wrong drive letter or something.

I know it all was really stupid of me so I now really need expert heavyweight help in trying to locate and recover that specific .tib file somewhere on the hard disk?

Welcome,
This is a hard one, the best software that I am aware of is Recuva
Recuva - Undelete, Unerase, File and Disk Recovery - Free Download
If that does not work, the next best suggestion is to download and use windirstat, it will show you everything that is on your drive.

Thank you for prompt and useful reply. Have tried Recuva with no luck. Will try your other suggestion

If its anywhere to be found, you will be able to see it with windirstat. If the files are very valuable, may I suggest stop using the computer and seek professional help. Did you know, that even after deletion, files can be found, they are not truly erased until overwritten several times.

Browse in using the WIn7 DVD or Repair CD to see if you can Copy & Paste - in Windows Recovery Console
to external or flash.

If this fails try Paragon rescue disk to recover data.

You might not be able to find the C data which could be scrambled beyond recovery, but the .tib might be intact to be copied out externally to be reimaged or mounted using Acronis program.

This is why your backup files should be stored externally. Use the Acronis boot disk.
