Help, can't get my color classic to boot internal HDD

[bschurman]

I recently acquired 2 color classics on CL and while I can boot them from an external CD drive, format the HD with drive setup 1.7.3 and install the OS, 7.1, 7.5, 7.5.3 or 7.6.1, I can not get them to then boot the internal HD after the install is over. I replaced the PRAM battery, made sure to set the startup disk in the control panel before rebooting and still no boot. I have tried the command/option/shift/delete/SCSI id at boot to no avail as well as holding down d. I know the HDs are not apple but they were booting up fine before I decided to wipe them and reinstall. Any help is great appreciated.

One HD is:

IBM: WDS-3200 216MB

http://stason.org/TULARC/pc/hard-drives-hdd/ibm/WDS-3200-216MB-3-5-SSL-SCSI2-FAST.html

and the other is:

IBM: DCAS-32160

http://stason.org/TULARC/pc/hard-drives-hdd/ibm/DCAS-32160-ULTRA-2ES-2160MB-3-5-SL-SCSI3-W-UL.html

Thanks,

Could be the old SCSI Voodoo again. Are the drives properly terminated?

 

[bschurman]

I'm pretty sure they are. I terminated the internal HD and removed the external chain. Do you know if the internal drive needs to be terminated on the CC?

 

[dorkbert]

Last device on the end of the bus should also supply termination power. Internal device and the last device (as in the way they are physically connected to the bus, not to be confused with SCSI ID; ID of internal drive typically are set to zero) on the external bus should be terminated.

See if you can boot from floppy and run disk utils to see if the drives show up. I am inclined to think it's a driver problem; Apple as a company has serious mental issues when it comes to third party hardware, particularly during the 68k days.

and the next thing which is overlooked 95% of the time, is make sure the system folder is blessed on the drive.

If these don't work, you might also have a faulty Bourns network filter or the SCSI controller chip is bad. Hard to say until you try all the other steps first.

I think I've heard of that network filter problem before, is this the one where prying the network ship off the board solves the problem?

 

[phreakout]

Technically, yes, but it does disable the external SCSI port if you leave the network filter out of the circuit. You can replace it with one from Digikey or you can replace with one from off of another model's dead board. I think Apple used the same model Bourns Network Filter as on the SE, SE/30, Classic I & II and some Mac II series machines, but don't quote me on that. Double check the numbers stamped on the part, along with the shape, number of pins and continuity of each filter to be sure. Use this as a guide for how the circuit is broken down.

It is essentially the same principle operation as with the Bourns filter linked between the internal and external floppy drive ports on these Macs.

Thanks for all the help. As always, much appreciated.

I finally found the solution here: http://new.lowendmac.com/sable/07/mac-drive-setup-patch.html

I was using drive setup 1.5 but not the patched version. Now I can format any of my drives and they are all seen boot and work like a champ.

It's always great when you track down the solution to an old problem.
