It works for me with a DDRS drive on a 2940UW (7880-based) board: # uname -rs FreeBSD 3.2-STABLE # camcontrol inquiry da1 pass1: <IBM DDRS-39130 S97B> Fixed Direct Access SCSI-2 device pass1: Serial Number RE2B9804 pass1: 20.000MB/s transfers (20.000MHz, offset 15), Tagged Queueing Enabled # camcontrol defects da1 -f phys -G Got 4 defects: 189:6:72 189:6:73 189:6:74 189:6:75 The stable build is from earlier this month (August). There shouldn't be any difference in behavior in this regard between a 7880 and 7890. I'd like to see you try the physical defect format with one of your drives on an Adaptec controller. In your PR, you specified block format, which I've only seen work for Quantum disks. (Not saying it doesn't work on others, but I know it usually doesn't work for IBM or Seagate disks.) Physical sector format usually works, though. You also didn't specify the PLIST or GLIST. You should at least try specifying the PLIST. You should also use the -v switch to camcontrol so you'll hopefully get sense information if the command fails. The NCR driver is known to be a little flaky around the edges sometimes, so I'm not surprised it might complain. Unfortunately, complaints from the NCR driver don't help much, because the only people who know how to decipher them are Stefan and Gerard, and they only pop up occasionally. I'll respond to the PR in a minute, so this stuff gets in the database. The bottom line is you'll have to provide more info before the problem can be fixed.
