Ok, so last night I tried hooking up a laptop hd to my pc with an adapter and the adapter didn't work. After I removed it, I restarted the computer and for some reason my F: drive (cd-rom) won't run. When I put in a cd, I can hear the cd spinning (the computer is a brand new HP, 2 months) but it says "f: drive failed because an I/O error." I went into the device manager and there is an exclamation next to the cd-rom; it says "Device cannot start"...I tried to uninstall it and reinstall and i tried updating the driver but no luck...I'm clueless. Any help would be greatly appreciated. thanks.
