Great - now you can submit a tested patch to the kernel, so that
future kernel versions will work with that hardware automatically.
I'll do that.
Do you know what drive is inside the enclosure? "hdparm -I /dev/sdX"
should work with a recent hdparm (>= 7.0); the "smartctl -d sat -i"
output would be good too.
