I bought a WD Caviar Green 1TB drive for my 533Mhz G4 (digital audio model) but I can't get it up and running - problems with boot sequence. I have an IDE drive in the cradle with it. I've tried two installations: 1. A LaCie eSATA PCI card with the SATA drive internal and the cable looped back inside so I can use the internal power. With the cable connected, the boot just stalls - disconnected, Tiger boots from the IDE drive but nothing happens when I connect the eSATA cable. So, I left it connected, tried a Cuda reset and reboot and all fired up. Disk Utility saw a 1TB drive, I added a 128 gig partition and it seemed OK until I eventually restarted. The boot hangs and I haven't been able to get the drive recognized since. So, 2. I bought an IDE/SATA adapter that just plugs into the drive and takes the IDE ribbon cable connector from the motherboard. No go - the boot hangs as before. I'm perplexed because it's just a bridge, to make the SATA drive look like an IDE drive. I've read some other threads on this site where these adapters have been used with no problems. Also, the LaCie card claims to be compatible with G4's.
