How to fix external hard drive

Does the drive show in My Computer ?

Have you checked in device manager for error ?

u can't read means, the contents inside the HDD or even the HDD don't appear in the computer.

is warranty still remaining?

also check the usb cable.

Hello... does an ICON appear in my computer when plugged in?

I previously did not see that you tried reading it with different computer.

Then it is the drive, or that cheap little circuit card inside the enclosure.
I am betting it is the circuit card. Enclosure are cheap. Buy another one and insert the drive.

Ive had this happen to me once when I pulled the driver files out from the base of the drive, the computer then did not know how to handle the device that converted the SATA port to USB and it would not boot.

I had to take the drive out and plug it into my computer, Windows then repaired it with a Scan Disk and it was able to be read. I moved the driver files back to the base of the drive and it worked just fine when I put it back together.

right click my computer and select manage and check to see if the disk shows up in the disk manager, if it does it may need repartitioning if it doesn't show then it might be dead, also check to see if it spins up by listening to the disc while being plugged in, if the drive is not getting enough power from the usb port it will not spin up or make a clicking noise, and you may need a double usb connector cable.

I Try many ways , check on manage all they didn't show . the icon on compt , also I hear clicking but not thing show up .

If you have PC, cable it as secondary/slave drive, internally. Set jumpers for secondary/slave to see if you can access it.

Otherwise, like I said before, buy another enclosure and put it in.
