I would normally reformat but I have a lot of stuff on the hard drive that I dont wont to lose. Im asuming that to fix the hard drive it has to be able to unmount KAINARC.ĭoes anyone have any ideas of how I can fix this problem. I have tried other repair/recover programs but get the same message: 'Could not unmount disk KAINARC' So I have opened diskwarrior (unbelievably long time to start up and scan disks) in the hope of fixing the hard drive, but when i try to repair I get the error message 'unable to unmount KAINARC'. Repairing disk failed with error Could not unmount disk So I try to verify and repair the partition KAINARC but get this message: When i try to verify and repair the partition I get the message:Įrror: The underlying task reported failure on exitġ volume could not be repaired because of an error I go to disk utility and both partitions are visable, KAINARC is mounted but JUNGLEMAC is not. KAINARC now appears on my desktop, but the partition of JUNGLEMAC does not.

I may have shut down the drive improperly to cause this situation. For this example, let’s say it’s /dev/disk2. You should see some disks appear like /dev/disk0, /dev/disk1, /dev/disk2.

Then paste in the command: diskutil list. I have a Western Digital 500gb external hard drive, with 2 partitions, 'KAINARC' and 'JUNGLEMAC', connected to my Intelmac (Tiger 10.4.11 via my firewire, i have connected via usb but the problem is still the same). Launch up Terminal.app(through /Applications/Utilities or through a Spotlight search).
