Hello. I currently work with an old G4 Power Mac (1.25 GHz, 2GB RAM) and have to mount a FW 800 volume (WD MyBook Studio Edition 1TB) to that computer so I can consolidate to it (Avid speak for copying some data). But it doesn't mount, and Disk Utility only shows it greyed out, and there is no option to mount it like in 10.3 and following. Is there anyway that I could mount it otherwise? The strange thing is, there are already two WD MyBooks Studio Edition drives connected and fully mounted. But even if I disconnect all extra drives, the one WD MyBook is still greyed out, even after reboot, which helped sometimes. PS: I also use this drive with a 10.4.11 PowerMac G5 and a 10.5.6 C2D MBP (Unibody). Can newer Mac OS versions leave some kind of mark, so that this older Mac OS won't allow it into its system? Thanks for any help.
