I have Sony an external hard drive, was OK for 13 month's. but after that, become useless, it is not recognize by my PC desktop anymore. The light comes on when I connected and there is E-local drive label at drive manger, but does not show any sizes. when I connect USB cable . The drive can be seen in the device manager or through My Computer. I am running 7 . I tried to using different PC, but no result. I changed the USB cable and no result as well. I tried that several more times with the same result. last time I did one different trial, I take off the hard drive USB interface module, and then concoction My desktop PC motherboard hard drive cable direct to the external hard drive, using that mother cable (hard drive cable) but no result as well.
there is a message comes after, E:\ is not accessible.
