Hey all, I have spent all day with a colleague wrestling with a 4 and 1/2 year old G5 tower that has been throwing up all sorts of cranky errors. (i.e. firefox crashes, flash crashes, programs wont load, itunes stops working, firewire drives make it insane). As part of the diagnostic flow, I attempted to verify permissions on the core HD. Disk utility only took a couple seconds to determine that there is some unknown error with the HD, and it cant continue. This leads me to believe that we are dealing with a flailing drive, which very well MAY be the root of the problems! Super. Time to make an external clone onto a fresh HD, and see if that helps. Install CCC 3. Open CCC 3, it hiccups on the dock, and then nothing. *roll eyes*. Install super duper. Run super duper. Now super duper refuses to let me make a bootable clone of the core HD!?!? Fine, if that is how you want to play this game. I get two SATA enclosures. Put the suspect drive in one, and then a fresh drive in the other. Plug both into my MBP where i run a CCC bootable clone. Couple hours later, it is complete. Lovely. Plug the new clone into the G5 tower, and it does not see it as a bootable drive. Bollocks. Okay, lets try the CCC clone again. Same result. I am very tired about this, and am desperate for options. Any thoughts much appreciate on this matter.
