I've recently upgraded the second hard drive on my Dell and can't get it to format fully.
The computer is a Dell Inspiron 531with an AMD processor running Vista. I've updated drivers for relevant devices so they're current. The original confirmation was 2 x 250gb hard drives giving 500gb. I have retained the original drive with the OS on and changed the second drive for a 2TB Toshiba DT01ACA200 drive. I've initialised the drive and used the 'new simple volume' wizard to set it up. It now shows as being Healthy (primary partition).
When formatting the drive, via Vista's disk management software, it refuses to go beyond 54%. I've also tried a quick format but this doesn't work - it says 'windows was unable to complete the format'. I've also tried using a program called HDD low level format tool but that shows I/O errors after working for so long. I should say this is second drive I've had as I returned the first as faulty when experiencing very similar problems.
Any help very much appreciated!
