The first thing to try: put the drive in a new enclosure. Might work. If not, throw the drive away and buy a new one. Nothing lost, except some money and the data you didn't copy before it failed totally.

Hi All,
I have a Maxtor basics desktop storage external HD.
I work on Win 7, Packard Bell Easy note Tx 86.
From time to time windows fails to recognize the maxtor storage.
I can see the an "Unkown device" item pops out in the Device manager for few seconds and then disappears.
Of course, I cannnot see the drive on My Computer.
Can you help please?
Thanks!
