I tried the hacks suggested, got HD SC Setup to recognize my drive, but when I clicked the Initialize button HD SC Setup crashed with a "Bus Error." Now, here's an update on the situation, and boy is it weird... I have a Mac IIci with a Storage Dimensions Quantum 105 internal hard disk. After reformatting the disk with the latest driver software from Storage Dimensions, I installed System 7.0 and tried to switch on virtual memory. The system hung on startup, after loading all extensions, but before displaying the desktop. I concluded that the problem must be with the Storage Dimensions formatting software (version 3.0.2). To prove it, I reformatted the drive and immediately installed System 7.0 from a disk set that I had used successfully on another Mac IIci. Sure enough, the system still hung in the exact same way. Just to be extra sure, I pulled the drive out of my IIci at home and brought it in to work. I installed the drive in my IIci at the office. It worked perfectly! The problem is not with the drivers. I can only think of three things to test: 1) I have a third party keyboard and a Summagraphics table on the ADB line on the Mac at home. I'll disconnect the bit pad and try again with an official Apple keyboard. Still, it's hard to imagine that an ADB device could interfere with virtual memory. 2) I will pull the RAM from bank B and try again. If it still fails I'll replace the RAM in bank A with the SIMMs I pulled from bank B. Again, it's hard to believe that this is the problem. If I have bad RAM, it should fail the RAM check on startup. 3) The last, and IMHO most likely, possibility is a bad component on the logic board, like a fried PMMU in the CPU chip. I can't think of a good way to test this, except by elimination. I can bring my official Apple internal hard disk home from work and install it in the IIci at home. If that machine still fails, with 100% six-color components and peripherals, it's a strong indication that the problem is on the logic board (as I will have swapped everything else). Of course, the IIci is off warranty, and a logic board replacement will probably cost more than just loading it with 32MB of real RAM and forgetting about virtual memory. So, net.gurus, any ideas? Can I test the PMMU directly? Is Apple going to offer me a free logic board replacement and a heartfelt apology for my troubles? One last note: technical support at Storage Dimensions has been outstanding. They answer the phone, return calls, and offer useful suggestions. Ken Weiss krweiss@ucdavis.edu
