aarrggghhhhh...

i've got a quicksilver dual 800 g4 which i tried to install a secondary hard drive into...

osx 10.2.8 booted and mounted both drives and i set the machine to boot from the new hard drive (with 10.3 on it). next time i switched on it only mounted the new drive and my old one has disappeared. since removing the new drive the machine wont boot and comes up in unix sh.05a# which (i've read) is some sort of single user shell. there's a few people having this message, caused by a number of things, but not many people are having happy endings...??

(i've checked the jumper settings on both drives - changed my old drive to slave and made the new one master...)

can't re-install osx on old drive because it wont mount and therefor i cant see it. it's no doubt possible to start entering unix code and solve the problem but i don't have a clue and don'want to risk making my old drive un-recoverable.

hhmmmm, i don't think the old drive dead, but it looks that way at first...
 
Make sure that the drive set to "master" is connected to the middle ATA ribbon connector, and that the drive set to "slave" is connected to the very end connector on the ribbon cable. Sometimes this can cause hard drives to misbehave if they're not located on the ribbon cable in the proper order.
 
thanks caca,

I'm now able to boot the new disk which already has 10.3 and disk warrior on it, but my old disk is not mounting on the desktop for me to fix. It can come up as a network disk when i try to set the boot disk...

hmmm.

At least I'm working again, I'd like to be able to recover the data from that disk - how can i access it with out it mounting though...??

cheers,

Ok... so, if the new drive is the only drive hooked up, does it mount? Also, the old drive -- if it's the only one hooked up, does it mount?

Do the problems occur specifically when both drives are connected at the same time?
 
no, i have both drives hooked up, the 'old' 40gb at the end of the ribbon (slave) and the 'new' 80gb in the middle (above it, master). now i'm booting off the new and can't seem to mount the old drive or access it in any way...

i havent tried just running the new one yet so i'll give that a go today...

cheers...

removed old hard drive totally now, and just got the new one in drive bay 3, at the end of the ribbon... it's working away great now, booting from that disk no worries... i'm just off to bench test the old drive in a portable hard drive caddy - i should imagine that everything's there... thanks for your help ...!!
