The error simply means that a previous drive logged a failure.  Once you run a complete diagnostic on the new drive and it passes without errors, that information should over-write what's there and the error will disappear.

If you tested a replacement drive and get a 2000:  error, that's another matter - it means the replacement drive is faulty as well.

Dear EJN63,

thank you very much for your reply, 

I just ran the "check disk" for hard drive errors and the the problem got solved, it seems there were some bad sectors in my hard drive. But now after running "check disk" the problem is solved.

thank you once again, :emotion-1:

Keep backups - any drive that shows bad sectors will fail -- most likely soon.

hey EJN63

I apologize for my late reply. Yes I have stored all the important stuffs on my external hd.

Thank you once again for your reply,
