Computer Won't Shut Down

Message #1 - Posted 2006/02/26 - Peter Sims

I've somehow managed to corrupt some data on my machine (Mac G4 733MH OS 10.4.5 896 MB). My boot drive is a 160 GB external and the internal is 40 GB. Noting several erratic behaviors (Disk Utility wouldn't open, Help Viewer opened but displayed no pages, etc.), I Installed-and-Archived Tiger 10.4 and Combo 10.4.5 on each drive. All appears to be well, with one exception.

When I issue a Shut Down command from my external boot, that command is executed, but then the machine, on its own, re-starts and takes me to the internal drive. The Startup preference pane on both drives indicate that my external is the chosen startup drive. Yet, a shutdown from my external results in a startup within my internal.

It's not easy (the System protects itself) and it's not a preferred option to delete any file with Startup in its name (You mean you don't want the machine to start?!?!).

Nevertheless, my best guess is that a file related to startup has been corrupted and needs to be trashed.

Anybody got an idea about my next best safe move??

TIA

You may have directory damage. If you have DiskWarrior 3.0.3, run it. If you don't have it, go out and get it. Otherwise, boot from your MacOS X install disk and run Disk Utility, then have it check out your external drive.

Hi:

Tried all that. No joy.

Still looking.
