Hope James will reply to this.
A friend gave me a 2tb hard drive to see if i could recover his data as he said the computer did not recognise it anymore. I have a similar problem with my own 550gb which i manage to sort out.
I first ran get data back the FAT version. This scanned for days then informed it the drive did not contain any FAT file format and must use NTFS version. On running the NTFS version getdataback informed me that drive did not contain any NTFS file format and must use FAT version.
So this is odd i now look on Western digital website ( wdbabv0010bbk-00) and unfortunately drive is out of warranty but that isnt the interesting thing. According to WD drive was only made in 350gb, 500gb and 1tb but system recognises it as 2tb.
I have then run a scan disk and stop it because after checking 15gb of the system the sectors were all bad.
I am intending to follow your recommendation from your forum but just wanted to know if it will even be worth it at this point
