Hi,
I had a look around but couldn't find advice which matches my case.
I have an Intel IMac a few years old, which recently started to freeze frequently. I checked the logs and found suspicious disk errors. Indeed running disk utility reveals problems ("invalid sibling link"). I have run disk utility from the CD but it seems unable to repair this problem:
What should I do next? It seems I have the following options:
1. run fsck. However the Apple documentation suggests that this is only useful if you cannot run the disk utility.
2. run another tool. There seem to be a number of them around. Which one is any good? I may spend money but the tool is unable to fix my disk.
3. reformat the hard disk. I seem to able to copy my files but this certainly takes up some time reinstalling everything.
4. replace the hard disk. Obviously this also would entail 3. I guess I'd only do this if it turns out that there is actually a hardware problem with the disk.
Any advice is appreciated.
