Recently my WD My Passport has become inaccessible.
I have tried the following:
Changing drive name
Tried it on another laptop(still wasnt able to access it)
But nothing has worked.
When I try to opening diskpart(from cmd) or disk management after connecting the drive its stops responding
The drive connects fines.Its lights also starts blinking and one can feel it moving as well which means the harddrive is itself fine.Windows installs its driver as well but then it doesn't allow me to access it.
If anyone can help me fix the issue it will be great.
I'm truly sorry to hear about the problems you're experiencing with your HDD. Do you have any data on that drive which you haven't backed up and you need to recover? Can you hear any strange sounds/noises coming form the HDD when you connect it?
You did pretty well with the troubleshooting so far. I'd also recommend that you try the drive with a different USB cables (preferably shorter than 12"), to see if anything changes.
If you don't have any data which you need to recover, you could download DLG (Data Lifeguard) and run both tests (Quick and Extended), to see what's the situation with the HDD. Here's how to do it: http://products.wdc.com/support/kb.ashx?id=NdhRFe
Hope that helps. Please let me know how it goes.
