I'll have to scan my mail archive for details ... Like: bash# ncrcontrol T:L Vendor Device Rev Speed Max Wide Tags 0:0 DEC RZ28 (C) DEC 442C 10.0 10.0 8 4 In my case TCQ started working after I upgraded the firmware in the drive.

Which one is dependent on the rev of the drive's electronics. Downloading the wrong fw results in a paperweight!!
