I replaced the original ibook (500 mhz) CD-Rom drive with the Toshiba SD-R2512. The drive plays DVD's, reads DVD- R and DVD-RW, boots from CD and over all performs fine. However, you cannot burn from the Finder or iTunes. The Apple profiler lists as "Not Supported" The solution to this is to use the english version of PatchBurn but there is a catch. ( Patchburn 1.1 for Jaguar/OS X 10.2.x - linked in the FAQ's CDROM/CDR section) Under the list of firmware options for Toshiba there are several choices before the names become gibberish (when you see it you'll understand). Select the FIRST unreadable option then restart. Afterwards the Apple Profiler will list the drive as FULLY supported!!
The following test were performed under OS X (10.2.8)
Burning from Finder-Passed
Burning from iTunes-Passed
Booting from CD- Passed (this is not affected by patchburn mods - as no HD drivers/mods are loaded when booting from CD )
Burning from Toast 6.03- Passed ( Not affected by Patchburn mods - Toast does not rely on apple burn support)
Erasing from Toast 6.03- Passed
Apple DVD player- Passed
The bezel that comes with the drive needs to be modified. Actually, you may be able to get around this. It seems that the top and left corner of the bezel makes contact with the ibook. However, if you pull the bezel off ( ever so slightly) on the left side it will close just fine. Otherwise you'll have to push down on the drive to close. The 2 nd option is to TRY and find the "ibook combo bezel". Good luck with that!!!
