|If there is no data on the drive that is irreplacable, don't even bother with trying to fix it. She should buy another drive.|
The external enclesure may be damaged as well.
Apparently this is a 2.5" hard drive. They're not anywhere near as tough as a 3.5" drive, everything inside them is considerably smaller than in a 3.5" drive, and it's a lot more likely something inside it is damaged physically, perhaps even the disk(s) (platter(s) inside the drive.
"BTW, dint even think of omening the case to get at the disks inside. That will guarantee to make the drive unless"
unless should have been useless?
It's not that it's impossible - it's that most people are not careful enough to do it the right way and don't have the proper tools..
You can remove and transfer the disk(s) (platter(s)) inside the drive to another drive the disk(s) is/are physically compatible with, but it's not a job for an amatuer unless you're an extremely careful person.
You would probably require oddball tool tips to remove the oddball fasteners, and you would have to be able to hold the disk(s) without damaging it/them so it/they can't move when you're trying to break loose or final tighten the fasteners that hold down the disk(s).
You would need a drive that both the disk(s) (platter(s)) are physically compatible with, and that has a logic board that will work with the data as it is on them.
Your best chances of the disk(s) (platter(s)) working in another drive is if you install them in a new or used working drive that has exactly the same model number.
