I have a Transcend SATA StoreJet 2.5. When I connect it to my Dell laptop, it beeps and the laptop does not detect it. How can I find out the reason and get it working again as before?
open device manager do you see your USB key if yes is there any yellow sign
Try connecting the drive to another laptop/PC if you have access to one.
There are essentially three possibilities:
Not enough power
Driver problem on your laptop
You mention a beep. Is it the drive or the laptop that beeps? Do you get any error messages? If the drive has lights, are they working as usual or is something odd about them?
