Hello, I am having problems with a partition that I use as my Time Machine backup. I have searched various previous discussions but can't seem to find a solution.


My HDD is split into 2 partitions and the Time Machine one doesn't mount, the other works fine. When I try to mount it using Disk Utility I get the error message: "The disk X could not be mounted. Try running First Aid on the disk and retry mounting".


Then without doing anything else I get another message "Mac OS X can't repair the disk X. You can still open or copy files on the disk, but you can't save changes to files on the disk. Back up the disk and reformat it as soon as you can." Which disappeared after a few seconds and the partition mounted.


When I try to repair the disk I get the above error message and another: "Disk Utility stopped repairing X. Disk Utility can't repair this disk. Back up as many files as possible, reformat the disk, and restore your backed up files." This appears after it says 'Updating boot support partitions…'.


When mounted, I can open it in Finder, but when I try to copy 'Backups.backupdb' I get a message saying "The operation can't be completed because it isn't supported." This is the same for 'X's Computer' and each backup folder. I can copy files and folders in each backup folder but this would be very tedious and probably Time Machine wouldn't be able to use the resulting files.


I have tried restoring the partition, through Disk Utility, to another HDD, but it just copies across the error. Disk Utility has been rather buggy as well, hanging on various operations involving the partition.


If anyone has any solution as to how I could save all of the data on the drive that would be great.
