I have installed a new hard, which was detected in BIOS at boot. It showed up in "my computer" & windows had gave it a drive letter & the drive works fine. But now if i connect my USB Card Reader windows does not recognize it as a card reader, it does not show as a device in "my computer" . In Computer Management the card reader is listed as a Disk Drive with 276 Gb of storage !.Device Manager shows the Card Reader as Generic Volume with exclamation marks. I have disconnected the new HDD & re-booted but it still does not see the Card Reader. Any ideas as to what as happened?.
