The CD drive on my iBook Clamshell will not close. I try to close it, and it buzzes and ejects without grabbing. The iBook took a minor spill while in a case, but it was maybe a 2 foot fall. I really hope I didnt damage the drive, and it wasn't even that bad of a fall. Anyone had this happen before? ive searched the forums to no avail, and did a google search with similar results. All help appreciated, Thanks.
