I was looking to upgrade the harddrive in my old G3, and I was wondering if you guys had any suggesitons for a good 120 drive, preferably 7,200 RMP

The program used to bypass the 128 GB limit is not recommended on many B/W G3s by the company (the Rev. A models I believe). The reason is that you must only use the slower of the two IDE connectors on the motherboard for this software to work. It is explained in greater detail on the site of the company that sells the software:


Back to the original hard drive question:

If you buy a 160 gb drive, you will see 128 gb or so. If you buy a 120 gb drive, you will see about 112-113 gb (give or take), so there is a good reason to get a 160 gb, especially because it is cheaper! (ebay is also a great source of new, cheap hard drives).

if you ever upgrade the Mac, you can reuse the 160 later. I have a 160 in an iMac400. I think the formatting limit is something odd like 137GB, of which 128 or so is useable.

Or you could look at an ATA-6 IDE/RAID card (although that's more money) and then you can put whatever size you like in - one of my B&Ws is currently running a 120 and two RAIDed 300s (not very quietly mind)

The Rev A motherboard had some issue with the secondary IDE controller and i believe it's not recommended to run a slave drive of any size off it.

I like Seagate. Anything has to be better than the cruddy, unbelievably noisy IBMs the B&Ws shipped with
