I have been having the EXACT same problem on my system: Mac 512ke, Sys 5.5, 
Finder 4.2, with a home-grown 40Meg SCSI drive.  The _exact_ same symptoms
have happened to me more time than I can count since I've had the drive 
up and running (about 3 months).  Unfortunately, Lawrence, the only solution
I've found is to reformat the drive.  I learned after the second time, and
bought DiskFit ( a great backup utility) and now I RELIGIOUSLY backup 
everything after each session (usually only about 3-5 minutes to backup).

What I have found is that after you boot from a floppy, say NO to "Do
you want to initialize".  Then I run Disk 1st Aid, although not in
"scavenge" mode, and it finds a problem and repairs it.  Then I when
I quit Disk 1st Aid, the SCSI drive shows up.  At this point, it works 
fine (i.e. for an immediate backup), but the system still won't boot off
of it - have to reformat to get that back.  Sorry.

On occasion, if I wait long enough (although 7 minutes sounded long enough),
the drive will actually boot, but as soon as I hit the reset or power-off,
I know I'll have to reformat.

Hope this helps, although I too would love to hear a good explanation
for what is happening and what to fix.
