Last week I updated to 10.2.6 and started having several problems which drove me nuts. I wiped the hard disk clean and reinstalled up to 10.2.4 which I had previously found to be stable.
A few days before wiping the disk clean, I had been getting an error whenever I inserted a CD or DVD into my PowerBooks DVD drive:
"You have inserted a disk containing no volumes that Mac OS X can read. To continue with the disk inserted click ignore"
This happens with audio CDs, movie DVDs, CDRs, CDRWs.
The problem is that I am still getting this error after having wiped the disk clean and reinstalling OS X.
What could be wrong?
