For SCSI-gurus

[quenthal]

Hi all!

I have Cyberstorm PPC, and I'm using cybppc.device for all my SCSI-devices.All harddrives are 68-pin, as is my cable.

 I have IDE cd-rom drive, which works nicely on my AOS3.9 CacheCDFS-filesystem.

Few days ago I acquired Toshiba XM-6201B SCSI CD-Rom drive, which is 50-pin device. I decided that I should switch using completely SCSI, and drop out my old IDE drive.

So here was my plan:
Active term - CSPPC(ID7) - HD1(ID0) - HD2(ID1) - HD3(ID2) - 68->50 active converter - CD-ROM (ID4, terminated).

Finddevice finds it at cybppc.device, ID4 and I can use software eject on it.

I have created CD0 using cachecdfs, cybppc.device and ID of 4. Mounting it doesn't create any error messages, but it doesn't show the CD icon on the desktop either even when there is cd inserted in the drive. If I try to use shell to check what is in the inserted cd, requester just pops asking for to insert drive CD0...

Any suggestions?

Try typing "diskchange CD0:" (no quotes) into a shell window. If you still get the "please insert..." requester, then you know your mount command hasn't stuck.

CD0:?? icon flashes for a short period on the workbench, as it should.

You didn't mention exactly how you're mounting the device driver either. Is it done from your SUS using the "mount Devs:DOSDrivers/#? ~(.info)" method, or are you doing it from a commandline?

I'm using that "mount Devs:DOSDrivers/#? ~(.info)" -line on startup-sequence for mounting.

 

If (mount) working correctly, when you type "info CD0:" it should return something like "no disk present", unless there is a disc in the drive.

It returns "no disc in drive" -message, even when there is one inserted.

Termination power is not a problem.

I tried in different way too:
Terminated HD(68pin) - HD(68pin) - HD(68pin) - CSPPC(68pin) -68pin->50pin converter (with big "ACTIVE" sticker on it) - CD-Rom(50pin) - Active terminator (68pin).

No luck with that order either. I tried the CD-Rom in both terminated and un-terminated mode while using above order.

Finddevice still finds the cd-rom drive, and I can use cd-player's or anyh other soft eject for it. Could it be that the drive it self is damaged, since that it rarely makes that "speed-up noise"..? I took the drive out of case, and noticed that it makes that noise, if I move it/tilt it a little bit while running.. ?..
