Legacy PowerMac Hard Drive Question

[MrCommunistGen]

I have a PowerMac 5400 which I gave to my mother since she's used to running System 7.6 and the 5400 is running 8.1 (which is pretty similar). I recently got her a G3 Upgrade and now I want to upgrade the hard drive. I have several just lying around, but my question is:
How big of a hard drive can a legacy PowerMac address. The 5400 was an education only model so its pretty uncommon, but it was built but it was built in 1996 and was available when the PM 4400, 7200, 8500, and 9500 were available.

Thanks!

137 GB limit?

I think that the limit is about 137 GB. So most folks who really want a huge disk on an older Mac end up buying a 120 GB disk. I think that you can buy a larger disk (for instance, 160 GB), but approximately only the 137 GB will be recognized by your Mac.

I don't have a definite reference for this.... so please don't take my word for the Gospel. This is just my recollection from my previous quest to answer the same question. I was in your shoes recently.
