Thank you all SO much. I must admit I am slightly overwhelmed by the quantity and slightly varying nature of the advice. But what a great forum! Though I am sorely tempted to just say what the f---, let's just upgrade the firmware on the old drive, it's behaved beautifully since Disk Warrior did its thing, I think installing the new drive first sounds good to me. But can I get a free download of OS9? I don't have it on a disk - so how do I "fit a new drive, and install OS 9" if my old drive is temporarily out of the picture? Also, I am not sure it's true about firmware having to go from OS 9 only, because I remember looking up which upgrade to do and there was one for my specific phase of OS/firmware, which is OS version of 10.2.8, and firmware/Boot Rom is 3.1f1... Hmm. Then there is the question of which drive to get. What do you guys think of this one: Seagate Barracuda 7200.9 Ultra ATA/100 120-GB Hard Drive model #ST3120213A Is my machine even capable of utilizing the 7200rpm speed? Oh, I just had a worry maybe that drive is only formatted for PCs, not macs... Any specific drive model to recommend?
