I had a computer at home that became so infested with ad/spyware that it would boot to the desktop and then just shutdown. I ran chkdsk on it and it found many errors with file pointers, etc. When it was finished its scan it said it did not have enough disk space to repair. After rebooting I got the missing NTLDR message. I put the drive in a working computer as a slave and it appears empty. There are hidden folders 'System Volume Information' and 'found.000' & 'found.001' which contain thousands of *.chk files. It looks like all the data is there it is just scrambled. Any idea how to unscramble???
