i’ve been using it for 4 month i think, and it worked just fine.i have been using it with usb 2.0 ports.
suddenly it stopped working with my usb 2.0 ports!
at first i tried some “first aid” like trying it over all my usb ports (when nothing else is plugged) i also was cheking the bios looking for changes in the USB category. none.
I took the drive to my friend, we plugged it to usb 2.0 port- nothing.
we tryied it over 3.0 port- and it worked! all files are saved.
notes:
1.when ive plugged the disk to both computers to USB 2.0 - no sound of pluggin somthin.
Since the drive works on USB 3 but not on USB 2 I would suspect a problem on the USB 2 port on the drive. I see you tried a lot. Are you using a cable longer that the one supplied and have you tried a new cable>
