Missing files when Windows 7 returns from hibernate w/ dual boot

Question

I have a dual-boot setup with Ubuntu (lucid) and Windows 7. I have the Windows file system shared on Ubuntu through Samba.

Occasionally, I am working on Windows and my machine will go into hibernate (i.e. when the battery level is critical). By default, my GRUB settings boot me into Ubuntu. So when I get back to my PC, sometimes I just hop into Ubuntu instead of going back to Windows. However, if I write any files to the Windows file system during that Ubuntu session, the next time I do go back to Windows (which resumes from hibernate), those files are missing.

Obviously, the state of the actual file system and the hibernate snapshot become out of sync, and Windows chooses the hibernate snapshot, overriding any changes I may have made thru Ubuntu. For now, I've disabled the hibernate option in the Windows power settings, but is there any utility I can use to get back some of those missing files?

Solution

Yes. In principle, it should be possible. Try a file recovery software. Recuva should help. http://www.piriform.com/recuva

Thanks. It couldn't find the missing files (might be too late now), but it seems like a great recovery utility.

It was able to find the files I deleted from the new directory I had created in Linux that went missing, but not the files that I didn't delete. Deep scan also didn't find the files.
