I fell into that possibly fatal 'sg_dd bpt= count=' by mistyping a
command line designed to help me nail down what the KiB/cdb limit is.
Looked to me like cdb's didn't match command line for such command lines
as:
sudo sg_dd of=/dev/sg0 if=/dev/zero bs=2k bpt=$n count=$n
I thought I saw trouble arose somewhere down below something small, like
below 8 MiB = 0x1000 blocks per cdb. (As you know, the t10 claim of cdb
max for ops like x2A Write 10 is xFFFF.)
If noone pops up here to beat me to the conclusion, I will myself try
this again in a few days and post to confirm/ deny this tentative first
impression of mine.
