Given how cheap backups are today, you may be today's poster member with today's story.
I have a 500GB Maxtor Drive that failed upon one power outage. When power came back and I tried to boot up, the Boot logo would stay for about a minute and a half, show a black screen then shut down. I tried the windows recovery utility to try and recover the drive but it gave me an 'unspecified error' message even though the 'C:' drive itself was visible. So this effectively prevented me from scanning and repairing any possible bad sectors. I bought a new drive, installed win 7 and attached the spoilt HDD so that I may try to use the usual recovery method but I couldn't boot even to the welcome screen, it just hang at a black screen and the PC shut itself down.
My final option was to get an external USB drive enclosure and connect it to my PC. The previous' C:' drive enumerates and even shows the file list but I cannot open the folders due to a 'cyclic redundancy error' The other 3 partitions just showed up as RAW. The USB enclosure isn't faulty either, I tried it with a different HDD and it worked perfectly.
When I tried using GetDataBack, it showed an I/O error the a 'no file system found' error. I need the data in this HDD and I am out of options, any other suggestions?
