Error type 10 when accessing hard drive with disk utilities

[Mr. Ksoft]

I just got a Quadra 650 board in, which is currently fitted with a 68LC040, and I've got it up and running. I'm trying to install Mac OS on the original drive, a 160MB IBM drive.

Unfortunately, every time I run a program that accesses the disk outside of the file system, like Disk Setup, Apple System Profiler, Mt. Everything, SCSIprobe, etc or a Mac OS installer, the computer crashes with an Error type 10. Apparently this is an error for a missing instruction. The only way I could see that being the actual error is if there is 68040-specific code being run for some reason, and the program sees the Quadra 650 and assumes there is an 68040 in there even though there is currently an LC040 in there. But I would imagine these programs don't use any of that, because why would you need the FPU for disk formatting?

What gives here? Can't install Mac OS until this error stops coming up. And yes, I've tried the basics like zapping the PRAM. This drive worked fine yesterday installed in my Power Macintosh 6100.

I have gotten Type 10 errors on machines that had memory issues. If possible, run something like Techtool Pro to test the memory, or if you have a PC available that takes 72pin SIMMs, pop it in there and run memtest86.

 

[Mr. Ksoft]

I'm not running with any SIMMs installed, just the 8MB onboard. But I'm going to see if I can get TechTool running to test it. Hope it's not the onboard memory or I could be in trouble!

EDIT: I couldn't find a download of TechTool that was either bootable or would let me make a boot disk, but I did find RAMometer. Which promptly crashed with a type 10 error after I clicked to start the test. I think that is in fact the problem-- onboard ram has gone bad. What a shame, nothing I can do now unless there's some way to bypass it.

Or bad capacitors messing with the memory bus.

 

[Mr. Ksoft]

Also a possibility I suppose. Caps look fine at first glance but of course that means nothing. Replacing is outside of my skill at the moment and sending it off for a recap would be outside my budget for now, so I guess this project will just have to be shelved for the time being. Damn, I've been having a horrible time with my Macs and them functioning.

With all honesty, recapping isn't too difficult. I thought that it would be a challenging job at first but as long as you don't rush anything you'll be fine.

It'll definitely be a skill that will save you a lot of money/effort in the long run.
