I have a STRONG suspicion that by "raw device" you refer to the
defective device which is enumerated as /dev/sdc . *ALL*
documentation and tutorials I found make a *MAJOR POINT* of *NOT*
mounting the defective device. "Permissions" therefor are a murky
issue. Point of fact, the specific physical defective object
predates me having more than casual interest in *nix.
There's a reason I asked for "hand holding" and specifically
asked for tolerance.
In a "user to user" support enviroment ther is an expectation of
querent doing his due diligence. I tried. I failed. M'aidez s'il
vous plait.

Whatever that needs to be mounted.
There *IS* a reason I explicitly stated that I needed an atypical
amount of hand holding!

I've gone to lenghts to defeat Debian's attempts to out-M$ Wm Gates.
I predate the 8085 when it was acceptable manufacturing practice
to cut/jumper etchs to "reprogram" 7400 series devices.
Tolerant help please.
