G4 Graphite / Hard disks

in Current Mac Hardware edited January 2014
Is it possible that 3 IDE hard disks can be used in this machine and how is it acheived?

    I was always under the impression that it was, but it didn't seem simple to me when I tried. I expect you have to replace the 2 port IDE cable with a 3 port one, and add an extender to the power line. There are 3 mounting locations on the bottom of the case, so that's not a problem. The other option is to put a HD in place of the ZIP drive if you don't have one or aren't using it, but that IDE chain is only 66 MHz, not 100 MHz like the other one.

    I'm no hardware expert, but I thought you could only have two drives on a single IDE cable -- a master and a slave. If you want more, you'll have to get a PCI card with a connector for the additional drives.

    The chassis should easily hold three drives, though, if not four. I currently have three drives in my dual 500 -- two on the built-in IDE and one on an Ultra SCSI 160 PCI card. It's a little bit cramped, but it works just fine.

    And since this is a hardware question, I'm moving this to Current Hardware.

    Technically you should be able to fit 7 drives with the purchase of: 2 ATA Controller Cards, 2 Additional U-shaped drive sleds, and drive kit for above the Optical*. You can find ATA controller card easy enough but the later will need to be hunted down. I've seen a few pictures of people running 7+ drives before but they aren't securely fastened down.

    I only have two currently, both hooked up using a Serial ATA controller card so don't take my suggestions as personal experience but it can be done.

    * IIRC, this deviates an ATA point from the Zip bay which is NOT ideal as it is only ATA-33
