X-Mailer: VM 6.72 under 20.4 "Emerald" XEmacs Lucid Sender: owner-freebsd-scsi@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org I recently bought a Tekram 390U2W controller and switched my IBM DDRS-39130 (68 pin) drive from SE to LVD, and also attached an IBM DRVS18D (SCA with a Corpsys LVD rated 80-68 converter), but instead of seeing 80 MB/s transfers, the output from dmesg and camcontrol say 6.6 MB/s. What's up with this? I'm using the supplied 68 pin cable and LVD/SE terminator supplied with the 390U2W controller. Even if I only have the DDRS-39130 connected, I still see it claim 6.6MB/s. I'm running 4.0-stable from early June, probably around June 10-12. Here's some of the messages from dmesg: Copyright (c) 1992-2000 The FreeBSD Project.
