why my drives disallow me to set the ARRE to 1? i tried multiple times.
even if i edit that, when i look the value after save&exit it's 0 again.
this is what i have now:
pluto# scsi -f /dev/rsd1.ctl -m 1

those werent listed, relevant?
actually i looked other pages (without knowing actually what i was
doing except that i assumed it being "safe")

should i edit that wce value to 1? (well, i did try, and it returns 0 just
like the other value i twiddled with)
(for the record on my quantum drive those all were "right" as default)

does that look sane? as it seems obvious, i only use scsi devices.
