When the error recovery code sees that particular error, it tries to spin up the disk. That probably isn't happening in this case. One way to test this out is: camcontrol tur -n pass -u 3 -v (you should get the same error as above) camcontrol start -n pass -u 3 -v (the disk should spin up, and shouldn't return an error if things are working properly) camcontrol tur -n pass -u 3 -v (If camcontrol start didn't return an error, this likely won't either. If camcontrol start returned an error, this will probably return the same error as the first tur attempt above.)

Some disks read firmware revisions or model numbers off the disk, I think. That's probably what is going on here -- you aren't getting the full inquiry information because the disk isn't spun up. > I don't think it's just a bum disk, because we accidentally ordered two > new disks (in addition to the one already in the machine) of the same > type - tried them both - same result.

Well, if it isn't starting, and you've got auto-start enabled, and the error recovery code can't start it, I would suspect bad 12V power. You've evidently got 5V power, since the disk can respond to basic commands, but it may be that you don't have 12V, since it can't spin up. > Please CC me on any replies, and also my colleague (mjabali@mintel.com) > - it's Friday and I'm off down the pub - but he's in the States and has > another few hours on this yet :-).
