Hmm, a READ_10 command.  And this isn't a normal sense error code,
it's a wdc(4) atapi error code. 0x44 means
(SKEY_HARDWARE_ERROR<<4)|WDCE_ABRT.
That translates to "non-media hardware failure".

It seems the wrong sense interpreter is being used to me.
And that SCSIDEBUG code path is printing out sizeof(void *)
of data rather than the full length.

But I still don't know what's going on.
