I have a problem with my parents Dell Vostro running Windows 7. The CD drive has disappeared from Computer. It also doesn't who in disk management.
In Device Manager there's an exclamation mark against the ATAPI iHAS124 B ATA device entry. I've tried uninstalling that entry and running a detect again. It reappears but with the exclamation mark still.
The CD works if you boot off of it.
I've also tried a USB CD drive with the same effect.
Any ideas as to what the problem might be?
