Ehh, check for viruses, torjans and etc. Possible jackass trying to mess
with you... Aside from that, check to see if the cd-rom eject button is
stuck. Otherwize the motors must have just went haywire. Most common
reason for that though I've seen is somebody messing with ya.
ive had a cd rom drive that when 'pushed' to close it
began to 'bounce' back out again and had to be held
shut!! reinstall drivers, try it in a diferent computer,
check ide cables, bios settings - or get new drive!
