My parents had a power outage the other day while the computer was on, and they say the computer flickered a couple of times then shut off. Since then, every time they try to boot it just continually restarts before getting to the desktop. It does the same thing when trying to boot in safe mode or last known configuration. I pulled the HD and put it in an enclosure to run a diagnostic on it and find the drive is not accessible. I can get the HP Recovery drive, but not the main drive. The properties of the main drive say 0 bytes capacity, 0 bytes used. It says file system is RAW.
Is there a way for me to repair this without a reformat/reinstall? If it comes to that, of course we will, but they don't have any of their data backed up (parents! Will they ever learn?), so I'm trying alternative routes.
