Ok, this kinda makes sense now. After someone (sorry, I forget) posted about
HVFExplorer, I found it on the web somewhere. One other thing I downloaded
was a System 7.0 bootdisk, and I was able to create this disk using
HVFExplorer, and boot the SE/30 with it. It didn't do much, but I cannot
mount the hard drive with it - sounds like what you describe below. I can't
even SEE the hard drive. The HD tools program sees "something" on the SCSI
chain, but that's about it...
I downloaded some of the disks from the Apple ftp site, but these are
.smi.bin files. I was able to turn them into .smi files (using StuffIt for
Windows), but am stuck here. HFVExplorer doesn't seem to deal with .smi
files...
Before MacOS 9.x password protection there was a nasty access control
application called At Ease. It went REALLY low level to keep you from
screwing around with things, if a disk is protected with at ease, the only
way to get at it is booting from another disk and updating the hard disk
drivers. Foolproof is a similar, thrid party application, and
there is also
a program (Disklock perhaps?) which locks the drive WAY down, you
can't even
mount it if you boot from another disk. If the disk is protected with
Foolproof or, more likely, At Ease, you'll need to reinstall the OS if you
don't have the password. If it is protected with an application like
Disklock (i.e. it doesn't show up on the desktop when booting from another
disk) your only recourse is to completely reformat and reinstall the OS.
