The first one locks up the 3w-xxxx driver (into an inf. loop)
when the error register = 0x11; this also resulted sometimes
in kernel lockup, also when doing raidstop...
The second one (0x51 move) is for completely broken
sectors/medium -- this makes SCSI core figure this one out
quickly and do the appropriate action, rather than retry
the command several times + timeout, of course without
success.
For the status byte, we're more generous (actually only interested
in the error bit); if found, good, else the effect is the same.
