I recently followed the instructions here to mount an Apple-formatted HFS external drive on Ubuntu. I transferred the files I needed, then unmounted the drive. Now the drive won't mount in OSX. In Disk Utility, the volume (top level) and partition (bottom level) for the external hard drive show up, but the partition will not mount. First Aid on the top level completes without error, but running First Aid on the partition level fails.
What could be preventing me from mounting the drive after following those instructions?
Any help would be greatly appreciated!
