Here's what's been happening: I talked to Al Whipple of ALSoft -- he's one of the coauthors of DiskExpress. He said that when the hard disk was initialized, any damage that may have been done by DiskExpress was wiped out. He proposed that there might be some problem with the disk drive hardware; since one worked, and three didn't, perhaps the one was using different hardware. No go. All four hard drives use Seagate ST225N mechanisms. Finally, just for grins, I dug out my original Hard Disk 20SC Installation disk, which had version 1.0 of the disk drivers, and initialized my hard disk with that program. Voila! It Worked!! So as a test, I used HD SC Setup version 1.4 to update the drivers. BOOM! The Mac II trahsed the hard drive. So I reinitialize with 1.0 again, andit works! So for now, I'm using the old old drivers with muy hard disk. They may not be the best ones, but at least they work. If one of the Apple employees who follows this newsgroup (not that I *didn't* say "Apple Reps" :-)) could kindly ask some questions, and perhaps try to reproduce the problem, I' d appreciate it very much. I suspect that there's a problem with the drivers version 1.3 and 1.4 when used with the Apple HD 20SC externl hard drive. Here's the configuration again: Macintosh II 1MB memory 1 internal floppy disk *no* internal hard disk. Apple video card, Monochrome monitor (als Apple) System v4.1 When the disk was initialized with HD SC Setup version 1.3 or 1.4, the Mac II would destroy the directory with no provocation whatsoever -- just boot with the hard disk, then reboot, and the hard disk's director has been destroyed. If I reinitialize with version 1.0, then the disk works perfectly. Note that the disk works fine with a Mac Plus with *any* of the above drivers. And that's an Apple Hard Disk 20SC, using the Seagate ST-225N mechanism. --Rich R-Squared Development Systems 134 Horseshoe Drive Williamsburg, Virginia 23185 (804) 229-2152 [After 6pm eastern time only] Arpanet: rs4u@andrew.cmu.edu Uucp: {your fave gateway}!seismo!andrew.cmu.edu!rs4u Disclaimer?
