He had a 9mm pistol on his hand, I don't think it would be smart :(

Never. That's why I'm so interested. Seems something interesting to
loose some time. Who knows I can create a sd-card-to-scsi bridge? :)
There is
no strange formatting, in the way that we normally think of
"formatting". It is not possible to reach those levels of a SCSI
device, so there are no incompatibilities. The host says "give me
block number 5324985", and sometime later, the target hard drive says
"hey host, here's the data for block number 5324985 that you asked
for". Zero format compatibility issues.
This is **VERY** interesting. I think I'll buy a zip drive tomorrow and
one or two zip disks and begin to read/write things to see how it works.
So bad I'll stay "grounded" for about 2 to 3 months before my new lab
gets ready :(
I'll do something even on kitchen table :D
