iMac G3 Hard Drive

Will any standard IDE hard drive work in a iMac 3G?  Are there certain brands that I should avoid? I want to replace the 40GB HD in mine.

 
I believe you have a 120 or 128GB hard limit (because of the drive controller), but that aside most drives should work I think. 

 
The controller supports drives of any size. The original iMac only supported booting the OS from within the first 8 gigs of a disk. Later slot loading iMac G3s can boot from anything within the first 128 gigs.

In order to use larger drives, you need Intech's SpeedTools ATA Hi-Capacity Driver. With it, the OS can be at the start of the disk and a partition which spans the rest of the disk can be mounted once the OS has booted.

I have a 2TB drive in my tray loading original iMac G3. I used XPostFacto to boot the OS from within the first 8 gigs while the boot OS is actually in the first 128 gigs. Once the Intech driver loads, /Users is mounted with the rest of the 2TB.

Drives larger than 2TB work (the controller sees them just fine), but getting XPostFacto to boot from one didn't work. 2TB is enough for me.

 
I found a 120GB drive which should work just fine.  I was going to make two 60GB partitions and put OS 9 and X on them so I can easily dual boot with the Option key.

2TB drive?  What the heck are you using all that space for?  I don't have 2TB of storage on my modern PC!
