I have an iMac 17", G5, 2GHz with OS X 10.4.10 installed (all software updated).
Recently my drive suddenly started to reject all types of disks. CD/DVD, written or blank, makes no difference. Once a disk is inserted it takes about 10-15 seconds and the disk comes back out. I'm not 100% sure if the disk even starts rotating...(difficut to make that out.
I have searched forums and other Internet sources but did not find any suggestions that may help me locating the source of the trouble which is either hardware or software.
I have also tried to clean the lens using a lens cleaner disk, but, surprise, suprise, these were also rejected so forget that option.
My point/question is this:
How can I indentify the reason for this behaviour?
Hardware (ie replace the drive) or software (reinstall OS X using an external drive ) which I don't have yet)? I do not know how I can determine the cause of this. Can anybody help? I do not fancy buying a new drive and then discover the problem persists because it is a software problem. Any way of troubleshooting this in OS X?
