[G4] Help needed on G4 after power surge

[Anne Keller-Smith]

Tom,

I'm hardly an expert, but my first step here would be to check for 
directory damage. Get your Disk First Aid and see if it repairs 
anything. Power surges really wreak havoc with directory info. I think 
Diskwarrior can also fix the directory.

The other thing - and I really know too much about this - a power surge 
connector protects against spikes but not outages. What you really need 
is a UPS with a generator to keep the computer running when the power 
goes out. APC is the most well-known of UPS makers but I think Belkin 
makes them too.

The reason the directory gets munged is because it is writing info on 
locations of things when the power goes out, and that info gets lost. 
So essentially your system components are still there, it's just that 
your Mac has forgotten where they are.
