Have a serious problem involving Norton DiskLock and SpeedDisk

Operating system: --Other--
Hi there.
I have a Twentieth Anniversary Mac running System 8.1. Today I
developed the following problem involving Norton SpeedDisk and Norton
DiskLock:
1. I ran Norton Speed Disk version 3.5 (?). I usually deinstall/
deactivate Norton DiskLock version 4.0.3 (?) when I do that, but
forgot to do it this time. (Can't tell you exacetly which versions I
have as I can not access my hard-drive anymore).
2. Restarting the computer it now crashes while trying to load the
first init (Norton DiskLock). The crash shows no window/ error
message, but the cursor freezes and the screen stays gray or, when
starting from external/ internal CD drive shows the desktop
background, menue bar and CD icon.
I have also tried the following in the meantime:
3. Restart from the internal CD drive. Computer starts with a grey,
slightly flickering screen. After a few moments the cursor freezes
but after a few minutes, computer starts looking for new start-up
drive and accepts internal CD. System crash "invalid instruction...
turn off extensions and restart..." Doing that CD starts (desktop,
menue bar appears, CD icon appears) until its time to load and show
the internal hard drive. At that point system crash as above (point
2).
4. Restart from external CD drive (SCSI connection). Computer starts
with a grey, slightly flickering screen. After a few moments the
cursor freezes but after a few minutes, computer starts looking for
new start-up drive and accepts external CD. The rest is as point 3 &
2.
5. Restart from floppy drive: System crash on trying to load the
Norton DiskLock init and using: Norton SpeedDisk, Norton DiskDoctor,
Apple DiskTools for PPC (not 8.2 version). The only floppy that does
not crash/ freeze the cursor is a modified version of the Norton
DiskLock Emergency Unlock Disk. This original version (4.0.3?)
however was ment for a computer running system 7.5. So, I had to copy
the Emergency Unlock Disk from the original disk and combine it with
a Mac OS 8.1 minimal system to get a floppy that my computer accepts.
Here, the computer starts-up than shows a grey screen and an empty
white window that is flickering quiet a bit. I can still move the
cursor, but nothing else happens.
I am sure, that I have updated with whatever free updates were
available for Norton Utilities and Norton DiskLock as I installed Mac
OS 8.0 and later Mac OS 8.1. But I have no "original" updated
Emergency disks for any of the above.
I am a also a bit surprised, that the computer will not let me start
from any external device. I have never had that before.
Thanks
Best regards

As you mentioned, it is not a good idea to run a disk repair/maintenance
utility on a drive that is protected by Disklock. It sounds like the
driver for the disk is corrupted and crashes the machine when it tries
to load into memory.
I'd suggest the following:
Boot the machine from the Apple OS 8.1 cd, while holding down "command,
option, shift and delete." This tells the computer to ignore the
internal drive and not even attempt to load the driver. If this
succeeds, you won't see the drive on the desktop.
Then, put in your emergency unlock disk, and run the program. It should
be able to see the drive (normally at SCSI id 0) and will search the
drive for the Disklock database. It should bring up a prompt, and allow
you to enter your Super User name and password, thus unprotecting the
drive.
If you succeed in this, you will want to launch the Drive Setup program
(unless the drive is formatted with 3rd party software, in which case
you'd need to use that) on the 8.1 cd, and use it to update the driver,
then restart the machine. At that point, the drive should be mounting.
If it still is not, boot from your Norton Utilities cd, and run the
Norton Disk Doctor. It should be able to see and repair the drive.
Try these things; if you are not successful, write back and tell me how
far you got and what happened. We'll take it from there.
