Hi, I have a WD5000 that has suddenly stopped connecting to my desktop and also laptop. I tried a new USB cord (purchased new from Best Buy) and it is still not working. The yellow light goes on, but I no longer see the drive listed. I tried reinstalling the driver from western digitals website but when I check under devices & printers or device manager, it shows me "unknown device" with a yellow ! mark in a triangle. I tried to troubleshoot it but the error is always the same... "no driver found". I have tried connecting to my Windows Vista desktop, Windows 7 desktop and my Windows 7 laptop and it is not working on any of them. Of course it has not been backed up-- and the only thing I care about right now is recovering the data off of the external hard drive. Can someone help? Thanks!
