Performa 275 Won't Boot From HDD With AppleSC CD Drive Plugged In?

Recommended Posts

Hey all, I'm having a problem with my Performa 275 - it refuses to boot from the internal HDD (1gb drive taken from an external LaCie caddy) when my AppleSC CD drive (not Plus) is plugged into it and turned on. I can boot from floppy just fine, but it won't recognise the HDD or CD drive...

 

Does this have something to do with SCSI device ID numbers? The AppleCD SC has another Centronics SCSI port on the back, do I need a terminator for that port? I must admit I know close to nothing about SCSI, the only other Mac I've fooled around with was a Pioneer MPC-LX100 which uses IDE.

 

Any and all help is greatly appreciated!

 

Thanks,

- Chief

If I'm not mistaken all the Apple external CD-ROM drives need to be terminated.  It certainly wouldn't hurt to change the SCSI ID on the CD-ROM drive though, just to see if that allows you to boot.

Okay, finally got an update on this. I bought a terminator and now the Mac boots with the AppleSC drive plugged in and turned on. I installed the FWB CD-ROM ToolKit extension and ran the program, and the drive is indeed recognised. However it still won't load discs. Every time I put a disc in the drive, it waits for a few seconds with the orange light on before spitting it back out again and the Mac does nothing...

Are you trying to read pressed discs (aka regular retail discs) or burned discs?  Many of the older drives have issues with reading burned media, but if yours is having trouble reading both burned and pressed there could be something wrong with the drive itself.

Not sure if it is the same problem, but I had that with my AppleCD SC Plus. The disc is ejected after a few read attempts.

The problem comes from leaky capacitors. I found these information very useful :

But I don't know is the board is the same with the Plus.

The drive is a Sony CDU541 (the board is the same as the Apple CD150 drive).

 

The board before and after capacitors replacement (thank you bibilit ;-)

It works very well now :-)
