I got a performa 636 for free and I'm thinking of turning it into a jukebox of sorts so I want to upgrade the hard drive.
I know it uses IDE drives, but since I only know about SCSI, can anyone tell me what sort of IDE drive I should be looking for?

for instance, will any of these work?

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2030183490

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2031526013

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2031133286

The reason I'm confused is that in this last ebay page the say the drive will work on a 630, 631, 635, 637 or 638 but they don't mention the 636. Is there a difference?

Yes. Any of those will work. The good thing about the 630 is that any drive with an IDE jack on the back of it will just plug in and work. I use a 6 gig drive from an iMac, and it works like a charm. Even though the 636 is not mentioned in any of those auctions, it will still work. The 63x series all use the same mobo.

Yep, all IDE drives are backwards-compatible, so they'll work in the 63x (which uses ATA-33 OR possibly something slower)!

I *think* it uses EIDE (Enhanced Intellegent Device Electronics) as original IDE was, in defiance of it's name, not very intellegent. EIDE was used right up to the G3/333 Beige. The 63x machines used non UDMA EIDE, where as the EIDE in later Power Macs did UDMA 1 and 2 maybe later 3, at least that's the theory I'm sticking to. Apple didn't swap over to ATA/33 (UDMA 4) until the B&W G3.

actually i think the 6XX series was a sub-standard IDE implementation, which actually stands for Integrated Drive Electronics.

the morons at Apple didn't even put in support for a slave drive.

Yeah, you're right, SVP, there was no ATA-33 until the Blue & Whites. Before them and the beige G3's, it was single-drive IDE only.

Does Mac OS 7 support large drives? Without a processor upgrade, the performa is limited to system 7, so what if I put a huge drive in it?

In that case the morons at Apple don't know what IDE stands for as I got "Intelligent Device Electronics" from the Perfoma 6300 Service manual!

I agree the lack of slave drive is a pain but where do you put it in a 63x? The one that got the majority of people was the Beige G3 and B&W G3 Rev. 1 having faulty slave circuits. They only actually got it right on the Rev. 2 B&W G3.

7.6.x is the only version that supports large drives. If you are keeping small files on the hard disk I recommend you try to find 8.1, which will run on all 68040 and LC040 machines, as it supprts HFS+ for non-boot volumes on 68ks.

Heres the run-down of supported sizes AFAIK them:

7.0 - 2GB
7.1-7.5.5 - 4GB
7.6.x - huge (more than 17.5 GB I know) may be as much as 2 Terrabytes or even 256 TB!!!
