When I plug in any external drive windows straight away says there's a problem with the drive and needs to scan and fix. It scans and doesn't find anything. This message continues to appear periodically as long as the drive is plugged in. Then when I turn off my computer, the next time I start it I get an instant blue screen of death (0xc000000c I think) everytime. Even if the drive is no longer plugged in. Turning off the pc by the power button then turning it back on causes it to boot fine no problem, and windows has no recollection of the blue screen. Even software designed to detect blue screens detects no issues whatsoever.
