I would either buy a sled on eBay _or_ -- if you don't move the Mac around (which you really don't do often, do you? -- just have them laying on the inside floor of the PowerMac case. Just place one on top of the other. If you're really worried you can connect them using a wire and a screw, so static discharge is now possible. /I didn't do that.../ I had two disks running inside my Power Mac G4 AGP Graphics, which I also got without a sled, for selveral months without any problems. > I've googled > and oogled many a time and wondered what could I use for SATA and ATA > drives internally in G3 and G4 Macs. :P You have the two options: 1) buying ATA drives limits you to 500 GB per drive, because there are no bigger capacities available for parallel ATA (and probably will never be). 2) Buy a SATA drive of your choice and use an adapter. You can use any ATA-to- SATA adapter that you can find (or was it SATA-to-ATA?) They are the same for PCs and Macs, because they are working at the hardware level. You you connect the SATA drive to the adapter, and the IDE cable along with the power cable to the adapter. Done. Now the SATA drive looks like an ATA drive (at hardware level!) to the computer, as if it actually *were* an ATA drive. For both options, you can use just any available size for ATA drives, but you will have to enable LBA-48 access -- which the controller chip of almost all G4s can do, but which was not enabled by the Open Firmware. Use this script and you should be done: http://4thcode.blogspot.com/2007/12/using-128-gib-or-larger-ata-hard- drives.html *Really* the only setback: you will have to make sure that Mac OS X is inside the first 128 (137) GB. So you will want to have a separate partition for that (e.g. 100 GB to be safe), just in case you ever have to reset your PRAM or if you PRAM battery brakes. I hope that helped, Andreas aka Mac User #330250
