I tried doing fsck in single user mode of Mac and also tried in Ubuntu with hfsprog utility, I got the same error – it says ‘Macintosh HD’ couldn’t be repaired. My Mac is not booting too.

(in Ubuntu)
abhinay@abhiomkar:~$ sudo fsck.hfsplus -r /dev/sda2
** /dev/sda2
** Checking HFS Plus volume.
** Checking Extents Overflow file.
** Checking Catalog file.

Invalid sibling link

** Volume check failed.

I believe that, this is because, the Mac partition is not unmounted properly in Ubuntu Linux, my suggestion is – do not mount Mac partition with Write permissions as the hfsplus write is still an experimental.

PS:
I’m still in the process of finding a solution to fix my partition…

Thankyou so much. I had tried everything, to no avail, but this worked a treat for me.

Furiously doing major backup now though, just in case . .

Thankyou!

Still getting “The volume Macintosh HD could not be repaired” when I attempt fsck_hfs -r /dev/disk0s5

When I do the fsck -fy I’m back to getting “Invalid sibling link… Volume check failed”

I think my next step may be DiskWarrior.

I have tried fsck_hfs -r /dev/disk0s2, and got the message,

the volum disk0s2 could not be repaired.

I also try to backup image and got message, input/output error.

Please help.

Thanks.

Dont give up if it doesn’t work the first time.

The error I was getting was the same as the original disk utility error
“invalid sibling link”

Thank you. If only all tech support were so happy.

Best Wishes, and many thanks,

I downloaded a demo version of Data Rescue II software from https://prosoft1.securesites.net/ and it was able to see all my drive’s folders. I bought the software and have recovered all my files! I just copied them onto another drive. It looks like I’ll need to reformat the bad drive but the important thing is I saved my data. It was worth the $99.

I tried all of the advice above and after trying Drive Genius (which also failed) I moved on to Disk Warrior. WOW! The disk was physically damaged and Disk Warrior created a temporary mount that allowed me to drag ALL of my files over to another drive. Unbelievable how effective this tool was.

THANKS!!!!

By the way, the consultant at Drive Savers gave me a quote of $2700 to retrieve my “lost” data. Very friendly guy, but I’m very pleased that someone took the time to post this article. Thank you very much.

I followed the instructions (a bit too literally at first), with no result, but nailed it the second time around when I noticed comments 37 – 41.

Here’s what I did exactly:
- Shut down imac
- Power down lacie
- Flip lacie power switch “on”
- Turn on mac (in normal mode)
- (lacie icon still didn’t mount/was not visible on desktop)
- open disk utility
- get the disk identifier for lacie (disk1s6 for me)
- ejected the lacie drive
- open a terminal window
- type this: fsck_hfs -r /dev/disk1s6
- observed this at the terminal window…

- opened disk utility to confirm lacie still not mounted
- power down lacie
- flip lacie power switch “on”
- watch the icon appear on desktop
- open iphoto and itunes (like regular)
