Ever since I installed iTunes my internal CD Rom can't read any of the CDs I've burned over the past 3 years! It can't even read new ones I've burned from disk images as HFS format CDs, it's got no problem reading a pressed CD in Mac OS format though. If I put a mixed mode or CD Extra disk in it complains about it, it won't read any burned CDs even if they worked fine before. I've even tried disabling the Adaptec UDF extension, all the iTunes extension and updating to OS 9.1 I've even manually installed the following drivers from the OS 9.1 installer using tomeviewer and it can't sort the problem out : Apple CD/DVD Driver Apple Photo Access Audio CD Access Foreign File Access ISO 9660 File Access UDF Volume Access I did use a patch to get iTunes to work under OS 8.6 before I got OS 9 and later updated to OS 9.1, it's like something's permanently wrecked my CD Rom and no amount of extension tweaking and updating can sort it out, at least as far as my knowledge goes. It's an old model, 300Mhz beige G3 Desktop bought in early '98. The CD Rom has always been kind of clunky but it's fine for audio CDs and pressed data CDs, it's just CDRs it goes nuts with. I can't boot from the external CD Rom either, for defragging my system partition and checking for viruses, I have to boot from a zip disk. I can start up from my internal CD rom with the Mac OS 8.6 updater CD but because my original system CD was wrecked and my current one is a CDR of the Mac OS 9 CD, that's not an option. Anyone got any idea how to solve this ? It's driving me crazy.
