I'm having a problem with my laptop (MSI GX640). I have a Buffalo 500 GB external HD that was working just fine yesterday afternoon but stopped working last night for reasons unknown to me. Some specifics:
1) Other computers can read the external HD just fine
2) I have another external HD, a Freecom this time but also at 500 GB, that my laptop can't read either
3) In both instances, though the hard drives don't show up on the "Computer" screen, connecting either one will cause the "Safely Remove Hardware" icon to appear, and when you click the icon you are able to select the drives even though no letter is assigned to them. The laptop will also try to boot from the HD if it is connected at startup. However, other than those instances, the laptop does not detect my ext. HD in any way.
4) Event Viewer logged Event 24620, BitLocker-Driver
whenever I tried to connect a HDD. I don't know what to make of that though; near as I can tell I've never used BitLocker, and none of my hard drives have any encrypted data.
I suspected that this could be a driver issue but I've tried updating drivers
of devices that I thought would be pertinent (USB controllers, etc.) to no effect. As far as I know my drivers are up-to-date, but I'd love to hear suggestions regarding what drivers to look out for. Otherwise, is there some other way to fix this issue? Thanks, all.
