8600/200, XLR8 Carrier ZIF G3/400 (8X), 640 RAM (interleaved, VM off), OS 9.1, Built-in video and iXMicro ix3D UltimateRez 8MB PCI in slot C1 each driving Apple Studio Displays (the legasy ones), Miles2 SCSI card in slot A1, 2 internal Fujitsu 18 GB LVD drives (Model# MAH3182MP, Revision# 0115) RAID 0, SoftRaid 2.2.2 drivers. I added 2 identical drives (also RAID 0) in a Burly-type case from OWC (sorry). I cannot boot when the external array is turned on. I cannot restart using the ext. array either, although I can choose it in the Startup Disk CP. SCSI IDs on bus 2 (Miles) are 0 and 1 for the internals and 2 and 3 for the externals. The active terminator on the outside of the external case glows steadily and brightly. I can mount the array using SoftRaid, transfer files to it and can use the files. I simply cannot figure this out. Any ideas? TIA. Seth Wissner

Seth,

Can you swap the cables and terminators with others to see if those are implicated? Sure sounds like they might.

Thank you for the timely reply. I suspected the same. I don't have other cables to try so I'll swap the external drives with the internals, when time permits. One other question: Is the terminator which ships with the Miles2 active? Regards. Seth

Before you go through the work of swapping drives, just make sure everything is seated properly, no loose ends. I thought I had a flaky terminator (and yes, the Miles2 kit would have an active LVD/SE I'm sure but never bought one). Took it off, looked for bent pin, dust, cat hair, etc. swapped with another terminator, then back again - and it worked!

I found a place with really hardy cables (internal) that come with heavy plastic wrap. Much like the twisted-flat style only heavier gauge and Ultra320 rated. I was looking because TWO granite style are causing trouble and can't see the drives when I use either. I felt it must be bad controller. So i bought another. Or terminator. Or bent loose or broken pin. You can also buy the Miles2 cable/terminator. In my situation, using my drives in external enclosures has been more reliable: better cooling, power, time to warm up before hand, unlikely to have an accident where opening the Mac case will accidentally cause a cable or cord to come loose.

What I did learn in the last year that every time I take apart, move, exchange drives, swap between internal and external... on and on testing, increases the likelihood of something going array.

Thanks again. I'll repost as things develop. Regards. Seth
