Invalid Sibling Link?

2013-12-12 Thread Glen
Spec's: G4 Sawtooth upgraded with a dual 1.25 GHz processor, 2 GB RAM, 2-100 GB 
HDD's, OS 10.4.11.

This G4 has been rock solid for a number of years following all upgrades. Today 
I found a frozen screen saver and no response to keyboard and mouse commands. 
No hardware or software changes have been made for weeks or months.

Restarted to the usual grey Apple startup screen with the rolling spoke/grear 
wheel and after two minutes the computer turned itself off. Thinking a hard 
drive failure I rebooted to a back-up eternal drive with success. The normal 
boot drive was not mounted and would not mount with Disk Utility.  I ran Disk 
First Aid on the damaged volume and received the message:

Invalid Sibling Link
Volume Check Failed

What does that mean? Is there any way to repair this?

I do have have recent backup so I could erase the wayward volume and restore 
the data. Any ideas to get this guy up and running? Thanks --glen

My HFS-fu is not as strong as it used to be, but this is (I believe) a
problem with the B-tree. This is a job for DiskWarrior; Disk First Aid
won't fix this.

If you need to get up and running right away, then I'd do that. Otherwise,
pick up a copy of DiskWarrior; Alsoft still sells PowerPC compatible versions
all the way back to OS 9.

Thanks for the quick response. I was thinking of DiskWarrior. Since I still 
have a number of PowerPC's it may be a good investment. --glen

Re: G4 iMac display swap?

 Anyone know if I can fit a 17 display with housing to a iMac G4 that has an

 I'd be really careful about that. I'm not sure if the base is weighted
 enough for a 17 (I *know* it isn't for a 20).
 
 I still use a 15 because the 17 and 20 seem to be too much for the arm
 and the strings stretch over time. I see far more sagging displays on the
 bigger ones than on the 15.
 

I don't think the weight with a 17 would be an issue, but what about 
connectivity? Is the hardware the same at the goose neck?
Would the MOBO be the same?

I don't know about the motherboard, but Apple used at least two different
kinds of displays, even within the same specific model. The necks also
differ somewhat, but I don't know to what degree and I've never done this
sort of surgery myself.

Yeah I think I will stick with the 15 a 17 would just be a tinkerers 
project:-)
