I have a Sonnet Tempo Serial ATA which I have used for a while. Firstly in a G3 B&W:booted os 9 or 10.3, then 10.4 no problem. Also at some point it had two drives on it. Until recently, it was in a G4 AGP with a 180Gb drive and 10.4. Just yesterday I found another identical drive and thought I'd try a RAID1 mirror. First I tried just two separate drives, which seemed fine. So I created a 180Gb mirrored volume and cloned my OS onto it. This will boot fine. However, I seem to be having erratic behaviour when it comes out of deep sleep. Seems to hang sometimes, work others. It sleeps fine with a standard OS volume on the card, but struggles with the mirror. Any suggestions would be welcome. But in answer to the OP, it probably depends on the pci card you have, but it should be possible. --- lriv2264 at aim.com wrote: > I have a G4 that I'm trying to upgrade to OS X > Tiger.
