To repair using fsck Restart in Single User mode (Command+S on boot) OR boot with the Install disc.At the command line, type: So log the successive runs and if the error reported is changing in successive runs, it is likely that REPAIR is fixing some problems in each run and it could be possible that using REPAIR repeatedly could solve your problem. The thing which can tell if it works is if you are getting a different output of the Repair in successive runs. Very important: If you are repairing, then REPEAT the Repair process more than once, to make sure it fixed everything.
#Volume could not be unmounted using live mode mac os x#
(You can't repair your startup volume while your computer is started from it.) The repair can be done by fsck or Disk Utility, however, the later is recommended by Apple if you're using Mac OS X 10.4 or later. This feature is called 'Live Verification.' If Disk Utility discovers any issues that require a repair, you will need to start up from your Mac OS X Install DVD and use Disk Utility on that disc to make repairs. You can repair only from another disk (not the startup disk) so get the (correct) Mac OS X Install DVD to boot or press Command+S (single-user mode) while booting.ĭisk Utility can verify your computer's startup disk (volume) without starting up from another volume. Using Disk Utility to verify or repair disks What I did do was load Data Rescue from CD and used the clone function to clone the broken HD to a FireWire external - for some reason it could see the drive and execute the clone. Not being able to mount the drive, I could not copy my files before trying the fix by any traditional means. Ĭlone the disk first if you don't have the backup of data (I use Data Rescue).

This could be good to get a manual backup by cp. Note: The disk usually gets mounted in read-only. Then try doing a manual backup using commandline tools like cp or ditto. If you don't have a current backup, you can try booting in Single-User mode by holding Command+S on startup.

Repair might let loose the volume/filesystem info all together and then there will be no other choice than to recover the data by some data rescue s/w like Data Rescue! Verification: Use Disk Utility and see the SMART status of your HD, although this isn't always reliable.īefore making any repair of the disk, make sure that you have the latest backups. Verification: Use Disk Utility and run "verify" to check it. This guide is purely based on my personal experience and is bound to contain errors. I don't claim to be an expert on this subject matter, just an (over)enthusiast Mac user. If your system is having some I/O error then it is sure that there is an HD failure issue.
