Replacement SCSI DVD rom - discs won't mount

[Mikeyy00]

Hi all,

Recently replaced the busted (SCSI) CDROM in my Performa 6360 with some NOS Pioneer DVD Rom off of fleabay. Drive detects, I can boot OS 9.0.4 installer from it (it installs OS9 from it no problem), but it won't mount inserted discs after.

I can run Apple System Profiler, it "sees" the drive listed under SCSI buses, it even sees the inserted CDROM name, but has a "note: not mounted". Drive setup lists it as a CDROM too.. but I can't get discs to mount.

Any suggestions?

it’s probably just an issue with the Apple CDROM driver. I would try installing FWB CDROM Toolkit, whose drivers support more models

I had to use Intech CD/DVD SpeedTools drivers in my 7500 then, now, in my 6100. Be careful to not use the Apple driver that came with MacOS 7.6 which is « universal » but crashes on boot.
Also, there is a patched Apple cd/dvd driver which should work iirc

Yes, it'll be a driver issue I expect. When you boot from a CD it loads the driver from the CD. If you don't, it uses whatever driver thinks it can cope with the drive, and if none can, you're out of luck.

I always used to use CD Sunrise as a universal one, but I think there's a universal version of the Apple CD-ROM Extension out there as well.

You can also modify Apple’s CD/DVD driver.

SpeedTools did the trick. Thanks!

(patched Apple driver kept bombing on startup even with other CD Extensions disabled. FWB didn't seem to work either).
