Strange problem: when I power up my Mac plus, I've got to first turn
on the Peripheral Land 30 hard drive and wait about ten seconds until
I hear a chuga-chuga-chuga sound. At that point I can turn on the Mac
plus itself, and boot normally. If I don't wait, and turn both on at
the same time, the mac will fail to boot off the hard drive (just get
a black grey screen). This is absolutely consistent and always
repeatable. Any ideas? I'm running finder 6.1 and system 6.0.2, and
it's happened with all the other systems I've had on here. Anyone
have any idea why, and what I can do to fix it?
Thanks,
--

A hard drive mechanism needs a few seconds to accelerate to speed, unlock the heads, and do various other "housekeeping" tasks before it puts itself online. If you switch the mac and the drive on at the same time, the mac will look for the hard drive too quickly, and thus it will appear that there is no drive present, and so the mac won't mount the drive. By turning the hard drive on first, you let it come online, and then the mac can mount it. It's very similar to the way the mac won't recognize a LaserWriter until the rollers are hot enough. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-\******/=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Gabe Wiener -- Columbia University \****/ "It doesn't matter how sincere it \**/ is, nor how heart-felt the spirit.

I think it was the "Lonely Hearts" revision that had this problem. The only way to fix it is with a ROM upgrade. Which will cost you. ROMs of this revision would not allow the Plus to boot with a hard disk that had not sufficiently "warmed up" first.

The problem here is not the PL30 drive, but the fact that James hasn't got the latest ROMs in his Mac Plus. These are available through your local Apple dealer and the upgrade should be FREE (mine was). I know this works, as I have the same configuration. Prior to the upgrade, the symptoms on my system were exactly the same. After, it no longer matters which is turned on first. Michael Naber

James: There's nothing wrong. I believe in the manual it warns that you MUST wait 10 seconds after turning on the PL30 drive BEFORE you turn on the computer. I've owned my Peripheral Land PL30Mb for almost 2 years (with my MAC SE) and always followed this instruction, and I've NEVER had a problem. So don't worry, you don't have a problem, you just have to wait 10 seconds. Jim Collymore
