If you ever had issues trying to get a 3rd Party CD drive to work in your Mac - this will be some required reading.
Thanks to Anthony Saxton, the author of ClipDragon, it's now posible to have a single modified driver work with both Apple CD drives, and any other SCSI CD ROM drive.
The screeshots below are for the Apple CD/DVD Driver 1.0.1. with additional descriptions for:
-----
Open a copy of the CD Driver in ResEdit and find the DRVR resources.
Open them with a double-click.
-----
Open ID# 32 with a double-click.
If you get an error about the resource size, open it using the menu item "Open using Hex Editor"
-----
The screenshot above for the Apple CD/DVD Driver 1.0.1 is representative of the changes to be made in all the drivers.
Find the original value at the appropriate row and offset, and change it to the new value.
Below is a table for first change in the various AppleCD drivers.
-----
The graphic above, and the table below show the second change to be made to the driver.
When you're finished, replace the original driver with the new one and restart your computer. Your Apple supplied CD ROM driver will now mount most SCSI CD ROM Drives!
Unfortunately, the edit doesn't work with every combination of CD drive and computer, but 90% should.
