I have two drives taken out of an external enclosure, which I mounted internally. If they are plugged into any internal Adaptec controller I get .5MB/sec of write speed (read is typically 6MB/sec). If I hook it up to an external adapter (same actively terminated LVD/SE cable) everything works fine. Specifics: Intel L440GX+ motherboard with 2 onboard 7896/7 adapters. Using those adapters, I get .5MB/sec. After adding a 2940UW PCI card and plugging the drives into the internal adapter on that I still get .5MB/sec. However, if I move the same cable to the external adapter everything works. This has been reproduced on a completly different computer (w/ Adaptec 7890/1 & 7880). Any [useful?] insight would be outstanding. --Chris To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
