At the end though they give File system check exit code is 0'.
I find that in both cases the process is taking a lot of time, especially I think at the steps checking catalog files' ,checking multi-linked files' and checking multi-linked directories. I ran First Aid from Disk Utility and also diskutil repairVolume on all the partitions. I did not rebuild the catalog but after this scan the time machine partition, /dev/disk2s2, mounted and I could mount or unmount all the partitions and eject the disk. It wanted to rebuild HFS+ catalog and ran some kind of scan.

I downloaded and ran the free version of Disk Drill. I could solve the primary problem by following the suggestion of. The problematic partition \dev\disk2s2 contains my time machine backup of three years. But now that the harm has been done, can you please suggest any solution? I hope this is solvable. First Aid in Disk Utility also does not work.Īll this could have been avoided if I had plugged the charger on time. Next I checked whether fsck is running: Apple$ ps aux | grep fsck unmountDisk gives the error Unmount of disk2 failed: at least one volume could not be unmounted. Operation times out if I try to unmount the mounted partitions ( \dev\disk2s3 and \dev\disk2s4). Volume things_kept on /dev/disk2s4 mounted Apple$ diskutil mount readOnly /dev/disk2s2 Apple$ diskutil mountDisk readOnly /dev/disk2 Volume on disk2s2 timed out waiting to mount Results of mountDisk and mount with or without readOnly for the different partitions are. I have tried out all the suggestions given in the post External drive does not mount after plug off without eject but to no avail.

I have tested the HDD with another Mac but the issues remain. The disk is also not ejecting and I have to just disconnect the usb cable every time. The other two partitions are mounting and I can see the files but they cannot be unmounted.
One partition which is used for time machine is not mounting anymore, though it can be seen in diskutil list and Disk Utility. However, the battery on my Mac was low and it turned off midway. It was working fine and I was transferring files from it to another external SSD on my MacBook Air (running macOS Monterey). I have a problem with my external HDD from Seagate.
