AppleCD 150 can't read CDs

Rather than copied data

Oh ok you tried older formate Mac world discs i see. Yes wait for termination block then. I take it you’ve cleaned the lazer?

Well I don’t think that cdrom are HFS formatted. I think the standard is something called JOLIET ins’t it?

What I’d meant was downloading and burning files on my OS X machine and then trying the disc on my SE/30 just didn’t work I presumed its was Hfs wouldn’t read it, anything i tried to burn just didn’t read but like others have said it could be due to many reasons on such an old drive. That said for me pre-recorded discs both data and music did work fine. Mind you i have a newer CD-ROM drive than you. I did try both CD-R and DC-RW neither worked for me. Hopefully the terminator will do the trick for you

Well, I’ll wait until receive the SCSI terminator for further tests. Right now I’ve tried with several music cds, always originals cds, and all have been recognized fine.

Yes, all the ones with which you've had no troubled are "Pressed CDs" If it's a 1x drive, EXPECT to have problems with anything else. If it works with CD-R media it's a bonus and most should be able to do so. If it doesn't it's still working within its intended performance envelope, second gen. CD-R is mostly backward compatible.

Maybe it’s a “special” unit. As “NIGHT STALKER” said it’s seems it’s a problem inherent from the first units in the cdrom era when the technology was in its first steps.

That's be jt or Trash. ;-) It's not a "problem inherent in the drives" at all. It's an unreasonable expectation that all early single speed drives would work with second gen. technology "Burned" CD-R media for which they were not designed. Again, in most cases they will work, in many cases not. To expect early drives to work with CD-RW media, a technology not even released until 1997 is pretty much out of the question.

CD-R media is still available to burn at low speed on a modern optical drive, It would be interesting to test older drives.

PowerCD is the one case where I've had a bit of luck with newer media, but it was designed to read Compact Disk, CD-ROM, VideoCD and PhotoCD media, the latter of which would be CD-R media "Burned" on a very expensive scanner/burner setup in a Photo Lab.

Good evening!!

Finally I’ve received the SCSI Terminator and I’ve found some time to test it out!! 

With the Terminator the unit can read data cd-rom so the Terminator is a mandatory for reading data cd-roms.

Thanks to all!!

Great news! YYour statement extends to the fact that proper termination of both ends of a chain is mandatory for doing anything (reliably) on the SCSI interface.

Glad its worked for you. Those Scsi Terminators are darn useful.
