Hello,I have a diskutil volume failed to mount Seagate 2TB USB 3.0 disk that suddenly has stopped working under Mac OS X asr: volume adjustment failed: unknown error: -123 Mavericks. The system won't recognise it. The funny thing is that if I attach the disk to my QNAP NAS, the diskutil force mount disk is seen just fine by the OS. I've read multiple websites with similar experiences; it seems to me as if the Mac OS X isn't as permisive as linux OS... and boy, is that
Mount_hfs: Invalid Argument
annoying I came across this article: http://perrohunter.com/repair-a-mac-os-x-hfs-partition-table/#comment-4644 . I must say that I got my hopes high when I started reading the post, because I felt it described my very same situation. Unfortunatelly, when I got to step #8, Mavericks would complain about the resource being busy, thus getting me stuck in there When the disk is hooked up on my NAS, I can see the data just fine. I asr adjust just want to be able to mount the disk one last time under OS X in order to transfer all the Time Machine backups I have there...

Disk utility shows it in gray color and won't mount offering me to check and repair it. Needlessly to say it won't repair it (neither in Mac OS X nor in Linux). Here's a picture showing Disk Utility Macintosh HD http://superuser.com/questions/667335/restore-whole-os-x-from-damaged-but-yet-somehow-accessible-hfs-partition is listed gray in Disk Utility: http://i.stack.imgur.com/zvBBr.png When I try to mount it as readonly in Mac OS X i get the following error message: $ sudo mount -t hfs -o rdonly /dev/disk1s2 /Volumes/OldDrive/ GetMasterBlock: Error 16 opening /dev/rdisk1s2 mount_hfs: Resource busy But! Linux will mount it as readonly. Which is really good. Even more: Mac OS X booted into single user mode (cmd+S) will allow me to browse the structure and cat files. I don't really want to just copy necessary files form that damaged disk from under linux. I want to restore that disk to my freshly installed one. What will you suggest me to do? Can I mount that disk under OS X somehow? If i can't, how can I get the data from that disk so OS X would recognize it as a backup and restore all my settings and applications into fresh installation? Thank you very much! linux osx mac partitioning data-recovery share|improve this question asked Oct 30 '13 at 11:35 Konstantin Bodnia 12515 Do you know whether it's an issue with the data, or whether it's a hardware problem? For the former, I've had some good experience with DiskWarrior being able to repair broken volumes. –Daniel Beck♦ Oct 30 '13 at 11:50 DiskWarrior sa

One with the OS and the failed to mount other with data. Yesterday, from a USB boot drive, I performed a clean installation of Mountain Lion to the OS drive. I created the USB boot installer from InstallESD.dmg that I received from purchasing the OS from the Mac App Store. Now I can't see or mount my data partition. I'm wondering if there's a problem with the MBR. In Disk Utility it shows up as "disk0s4", but it's greyed out. Any ideas on how I can mount the data partition so I can get my data off it?
