[X4U] 17" PB G4 running 10.4.8 Trifecta (Surface Scan errors and Invisible Folders)

[Lee Licata]

Dear list,

I have "won" the trifecta. In the last 2 weeks, my LCD display  
failed, so did my internal hard drive, and my logic board went while  
restarting with the failed hard drive (which was unknown to me.)

Did have a major backup completed 24 hours before the drive failed...

Now, have a new, bigger hard drive, and a "new-to-me" logic board.  
Display maybe a week+ away.

So, after putting a basic system 10.4.8 on the internal hard drive,  
ran techtool pro and the surface scan test showed 31 errors.

Erase and reformatted using Disk Utility and restored the drive.  
Still have the 31 errors.

Any idea how I can get rid of these errors. I believe I want to map  
out the failed segments and I thought that disk utility did that, but  
not 100% sure.

And, during restoration, three normally invisible alias folders are  
visible: etc, tmp, and var.

Used Cocktail to make all invisible files and folders at the root  
level visible, and then invisible. They remained visble.

So, any suggestions to make these  invisible again?

TIA

Lee
