Unless Seagate have started sticking inch-round labels with a picture of a fish and "BARRACUDA" over the spindle motors on their Hawk family disks, I suspect that it was, indeed, a Barracuda; my notes say ST15150N (Two PWA's in the old CDC style, spindle motor sticking through one of them, SCSI connector & jumpers on the other at right angles against the back of the chamber) (Yes, I'd expect to be able to tell the difference 8) Thinking about it, it's possible that there was a _really_small_ fan in the case (it's basically the width of a 3.5" drive, twice as high as a 1/2-height drive like the 'cuda, and with about 2" of clearance behind the drive. The back panel's covered with SCSI connectors, power connector, switch & ID selector, hence my assumption that it's convection cooled. If there's a fan, it'd have to be hidden under the drive forward of the power supply... Either way, in comparison to the earlier 'cudas I've met, it was cool and quiet, which was really all I had to say 8) > Rod Grimes rgrimes@gndrsh.aac.dev.com -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] My car has "demand start" -Terry Lambert UNIX: live FreeBSD or die!
