I have three internal drives in my machine.
I lost a drive recently (mechanical failure) which was the original hard drive that came with the machine and was also my start-up disk. When it went, I'd at first thought that both it and the other drive on the bus had died because neither would show up in any disk utility but once I had removed the defective drive the other drive showed up fine.
However after just buying a new 120Gb drive to replace the original drive I discovered that again with both drives plugged in, neither will show up yet they both work fine if they are the only drive connected to that bus.
both are set to slave (as at the moment the startup disk (master) is another drive which is on the slower IDE bus with the CD-RW. I'm not sure how much difference correct jumper settings make with the mac anyway because none of them have ever seemed to matter before.
Can anyone think of any simple reason this might be happening? or is it just a screwed up bus?
thanks in advance!
