i seem to have a big problem that has left me scratching my head... on my wifes B/W 450 G3 i have installed 10.3.5 on 2 separate internal harddrives. first off, i don't have any 3-rd party junk like shapeshifter or APE installed to mess with the system. i only use Final Draft and Photoshop on this machine. but here's the problem: the preference for everything on these disks starts getting corrupted for no reason, first ownerships change and need changed back to even access files. then eventually i can't access anything on the drives. trying to repair disk permissions using disk utility from either form system or OS X cd results in either "lost connection with disk manager" errors, or disk can't be repaired errors, or just usually a crash (kernal panic dialog). and as last resort, a clean zeroed system re-install always fails halfway through base subsystem 2 (although a new install is possible if i put the drive into my G4 for installation). now the machine boots up fine, but the finder won't start. i have a dock, and can access system preferences panel, but not my harddrives or a finder window. i've tried to delete the finder pref. in single user mode, but it won't let me repair the volume. i'm at a total loss. the harddrives are new and I've run every test TechTool Pro 4 has on the computer hardware and harddrives- all passing fine. so how can i stop the Prefs. from constantly being corrupted to the point of unusbility?? i tried Panther Cache Cleaer, but that's how i eded up locked out of the finder at present i believe. please help someone!!
