I'm still new to working with Macs. Currently, I have a single processor Mac G4 with a 60 gig hard drive (Hitachi Brand). The OSX I have installed is 10.2.6 I just bought a 200gig hard drive (Western Digital Brand) and tried to install it as an additional drive, and now, when I boot up the system, I get the apple loading symbol and (what looks like) a "no smoking" sign (without the cigarette - he he he) I have set the jumper leads to both Master/Slave option, and Cable also. I have noticed hearing a "click" sound on starup also. In frustration, I removed the 200 gig hard drive and tried to boot up again with the existing 60 gig drive and I still get the same error. What have I done wrong? I'm scared that I may have lost everything on my 60gig drive or worse still, my whole computer is useless. Any help would be greatly appreciated. Thank-you...

check jumpers again for 60 gig only,and boot with cd, check cables and other wires that may be lose, try using 200 gig by itself, and boot with cd, and check for errors...:)

Rebless the system folder on the 60GB disk using ur system cd

Make sure that the 60gig is set to exactly the same setting as before re: the jumpers, and is on exactly the same spot on the cable. OSX has a very specific way of searching for a bootable partition..the disk, rdisk, and partition must be exact (if it's like other unixes). if it now doesn't boot use your OSX cd to boot and select the startup folder on the 60 gig. After you have succesfully booted you can try the 200 gig again..setting it only to slave or cable select.. The click can possibly mean a bad drive (it can happen even to new ones..the shop should be able to check it out in 5 minutes). I've had a couple of Fujitsu drives that gave that click and then wouldn't mount or let the system boot.. I also don't recall if the G4 needed an ATA 133 card for accessing anything over 128 gigs..but i think the earliest motherboards (the ones like the earlier G3 rev.2 ones) might...

Thanks for your help and suggestions guys! I just solved the problem. One of the pins within the 40 pins at the back of the hard drives was bent, so with a little delicate work with my tweezers, I straightned the pin and reinserted the hard drive to my Mac. And... you guessed it, my Mac drive was back. Woo Hoo, all is not lost. However, I do feel a wee bit stupid. Thanks heaps!!!
