It could possibly be hardware failure, but you normally wouldn't see files just disappearing, because that would mean the hardware problem is affecting the file system table, which would most likely render your system unbootable. Saying that, anything is possible, but I think it's more likely to be an NTFS MFT corruption caused by the operating system. This happened to me once - Windows is not bug free. Windows had nuked the MFT and all backup copies of it on the drive and I had to buy expensive recovery software to deep scan the drive for hints of any file it could find (which I luckily succeeded in). It could also be a virus/root kit, but whatever the case, you should definitely wipe the drive after backing up/recovering data before trusting it any further. It would also be best you do a proper scan of the disk using GRCs SpinRite or one of the many Linux distros that have utilities that scan your hd for defects before you trust it to store your data any further. If anything, I recommend you first boot your system into an Ubuntu live cd and check the HD file system to see if the files are still missing before proceeding with anything else.
