Help: SCSI disk is always locked, even on floppy boot

Hi all,

Coming here for a last resort, because Google keeps giving me OSX advice;  my System 7 mojo was really strong back in the day but I'm new to retro (as of a week ago) …

Color Classic Mystic with 1GB SCSI disk (also transplanted along with the motherboard), containing 7.5.5 copied into a few renamed system folders by the previous owner.

Worked fine for a few hours.  But now it is always write-protected, even when rebooting with floppy boot disk.

I'm a bit afraid of installing FWB SCSI drivers because of the 2 ProDOS partitions for the IIe card.

But it looks like I can't do that anyway.  Maybe I can format it but we're not that desperate yet.  That can wait for my SCSI2SD.

Things I did successfully before it happened:

 - about 10-20 reboots

 - blessed a different system folder

 - a few goes in 24-bit and 32-bit to play with CS ethernet versus Apple IIe Card

   (I couldn't establish a network connection on classic or OT yet though, saw "ethernet" option in Control Panel but nothing in boot screen parade)

 - moved folders around, cleaned up the desktop into a cleanup folder on the root

 - renamed the HDD volume (already customised, but renamed again)

 - turned off a few Extension Manager items to free up RAM

   … this was the last thing I remember being able to change, now all prefs in everything are complaining they can't save.

One more thing:  Several reboots ago I had no disk detected, I think due to the motherboard having one dodgy gold tooth.

It's been okay since inserting the motherboard twice now;  but I'm very reluctant to keep removing it.

To be clear:   Since my last motherboard reseat, I had a good couple of hours in read/write.

Haven't got anything external SCSI yet.

CK.
