I have been given a HDD to fix. Its a western Digital 500gb scorpio blue WD5000BEVT.I plug it into my laptop via a usb cable and external port designed to quickly mount 2.5" drives. I have windows 7 installed. I used testdisk to try and get the drive back to normality but failed,Now the problem i am having is that windows now repeatedly asks me to format this drive and when i attempt to, it fails to do so. My next step was to use a easus partition manager to format it so i tried with that and got the same result. So i have a drive that is RAW and keeps cutting out and rebooting but it shows in disk manager. I also then tried getdataback free software and got some results from the drive reports but it would not scan fully because of too many bad sectors but i managed to get some screen shots of the cylinder size etc. Now i am thinking that the cylinders sizes etc. maybe even the drives MBR needs resetting somehow to stop the drive rebooting constantly. If anybody is not bored with this post by now and is still reading and think they can help then please do. I have also plugged in this HDD on my desktop PC and i get the same result so its nothing to do with cables etc..its this WD drive that now has this cutting out and restarting problem. I am thinking once i can stop the drive cutting out and restarting i can then attempt a clean format and recover some data. Any help/advice would be highly appreciated. Many Thanks.
