Last night my 250GB Seagate HD, housed in a FW400 enclosure stopped working. First I thought it was the enclosure as it looked like the power to it had died. So, I removed the drive and installed it in another enclosure. When connected, again via firewire, I get the error "The disc you inserted was not readable by this computer". I went into the disk utility and the drive shows up but with no volumes and even stranger it has a new name. Disk First Aid is not available as the options are greyed out. I have a lot of data on the drive, some of it backed up however about 30gigs is not. So, I tried using DiskWarrior to try and repair the drive, however it does not see the drive. So after much frustration and poking around various forums I used Data Rescue II. It seemed to fix similar issues that others have been having, so I thought I'd give it a shot. I was excited to see the drive being read, even to the point that it had located 12000+ files. However, after the scan was complete the results came back with no files recovered. Please help, what can I do to salvage the data off this drive.
