For reference, these are the results of the HDDScan And heres a screenshot from windows: I can't seem to see any data on the HDD anymore since its not being recognized as formatted, so there's no way to make a backup! The drive still shows up in Windows Device Manager, but it shows up in Windows as a RAW drive (primary partition), with 2 other unallocated partitions. It was originally formatted as NTFS. I tried booting from Linux Ubuntu but can't see the the drive either. I have already connected it to different machines and on a HDD dock as well. Still the same. What do the HDDScan results mean? Can you recommend troubleshooting and data recovery software/methods? Would running these utilities cause further harm? For fear of damaging the disk further, I have not run chkdsk or testdisk on it yet. Please excuse the newbie question, Is my drive the notorious 7200.11?
