Below are set forth my drives and host adapter specs, I'm trying to replace my smaller (18gig) SCSI slave with a larger (80gig) IDE but can't get the SCSIs to master an IDE drive, ever. (all SCSI herein are SCSI IIIs with 68 pins, brand name "Ultrastar" by IBM made in Ferb of 2001 Thailand, Utra3 SCSIs). The 80gig IDE is not fast enough for use as my master drive. I've tried what another poster sugested to put the IDE on the secondary IDE cable but it did not work. I may not have the jumpers on the drives correct though as someone at a computer center set them up a while back (on the SCSI IIIs).
If you would be so kind I need some instructons on setting jumpers on these IBM SCSI III drives as the jumper markings are more complicated than on any IDEs I've dealt with before please. And where to set the settings on the host adapter if you please. I need to get it right the first time hopefully because it is a $6,000 computer and I hate taking it apart and rubbing up against the memory sticks, chip etc. Already I had a crash that was only resolved by my "jiggling" the power & 68 pin ribbon cable which bugs me that something this pricy would have such a CHEAP connector system, can you replace and get a better connector system? I work in robotics and If I came up with such an unreliable and damaging rig I'd be fired! Why do SCSIs like this suddenly crash (more than IDEs) and when I "jiggle" the connectors (even with new ones) they come back up? They are grounded and fanned and I do not jar or handle them while running. The computer is an Athlon 64 FX53 in an ASUS SK8V Motherboard with DDR 400 ECC Memory with a "VPower" 400 watt power supply. Thing runs hot so I run it open case with a table fan on it. Fan & computer hooked through CPS system. Could a bigger (or better) power supply be in order? Is this causing the Molex power connectors to fail maybe? I'm still trying to grasp the Int19 aspect as well.
Thanks so much for all the kind attentions, frab.
