Booting problem due to hard disk failure?
by vernonlouw - 5/4/12 3:06 PM
iMac 24', OS 10.6.2 Snow Leopard, was shut down during booting process, after which it would not boot beyond the apple logo and rotating disc.
I know very little about the technical aspects of computers, but tried to follow instructions from online forums.
Not able to boot in safe mode.
Not able to reset PRAM.
No change after SMC reset.
Loaded start-up disk, used disc utilities, verified disc, and attempted repair disk, with following message appearing:
Invalid sibling link
Rebuilding catalog-B tree.
The volume Macintosh HD could not be repaired.
Volume repair complete
Updatig boot support partitions for the volume as required.
Error: Disk utility can't repair this disk...disk, and restore your backed-up files.
Then a pop-up window appeared:
Disk Utility stopped repairing "Macintosh HD"
Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
My question is:
1. Is there another way to solve this problem?
2. Fortunately I do have most of my files backed up, but there is some important recent stuff that has not been backed up yet.
3. How do I back up files from this point on? I can't seem to access anything on my computer except Disk Utility.
Your advice will be greatly appreciated.
