I'd be really grateful if someone could help me with this. After the power supply on my G4 Graphite (466) died, I purchased a G4 Quicksilver 933 running 10.4.11. I decided that I would take the hard drive out of the Graphite and put it into the Quciksilver as I have lots of files that I really need on it. However, on opening up the Graphite, I discovered four, yes four hard drives inside it! (My ex looked after the tech side of things). I was a novice when I first opened the computer up (am still a novice) and I didn't pay attention to which of the four drives were actually connected. Anyhow, I don't know which of the four contains the volume with my work on it. Two of the four drives mounted successfully in the Quicksliver, the other two didn't. However, of the two that did mount, the volume with my work on it wasn't on either of them! The other two fail to mount although Disk Utility sees them both and their RAID sets? (I don't know what this is). Anyhow, I can't see the volume with my work on ANY of the four drives, which is extremely annoying. I know about the master/slave thing. To make matters worse, yesterday, the original drive that came with the new Mac (the Quicksilver) seemed to die on me, it now makes chugging noises and the computer fails to boot. As far as I know, of the five drives, this is only one (that works) with an OS on it. And I didn't get the install CD with the Quicksilver (it was cheap - well cheapish). Can anyone help with any of these issues? Is there anything I can do with the Quciksilver drive (Maxtor 60GB) to make the computer boot? (remember I don't have the install discs) If I do get it to boot, how can I find out, which of the four OTHER drives (from the Graphite) contains the volume with my work on it? (I can't ask the ex, we're not on speaking terms ) I really am losing the will to live with this. Thanks in advance!
