|So, the external drive is listing in device manager in the Disk Drive section? Is it listed by the name and full model number? |
Did you try the Seatools repair options? Look at the link below.
From your description it sounds like the drive has mechanical problems. Did you drop the drive? Noise can be from two different sources. Bad bearings or crashing heads.
Go to the link below and listen to the possible noises for your model.
Does the drive show in My Computer?
When viewing Disk Management expand the screen to full screen. The external may be the last drive listed.
Do you have a card reader or do you use flash/pen drives?
If you finally do get access to the files I suggest you copy the most important ones back to your internal hard drive as quickly as possible.
