the 630 was the very first ide controller in a mac. It has limitations. Perhaps the poster above had a drive that downgraded itself to work at that speed. It is a good idea to try older hard drives in this process.
I don't know about OS 8 but OS 7 does limit me to 2 gb per partition perhaps it's my controller. Seriously though this does affect the macs described in the apple note I linked above. This was new tech at the time, there was limitations of the ide controller.
Personally if I were you clinton, I would add a nubus scsi controller and put a big 18 gig in it. Also charge 300 for your trouble and parts. These are 15 year old machines, he should be praising the lord his computer has lasted this long. If it has lasted this long it will last another 15 years!
