Disk Utility is a frontend for fsck, but it may be preferable to run
fsck directly. Try

`fsck_hfs -c 2200m -fyprd /dev/diskxsy`

Repeat until a) fsck_hfs does *not* say "File system was modified",[1]
or b) the problems fsck_hfs finds and fixes/does not fix do not
change. In other words, if fsck_hfs gives up after the first try, try
again.

(This is assuming that the filesystem is the problem and not the
physical disk, of course.)

As Jan and others said, MythTV isn't the cause of the failure, and
external enclosures aren't a good idea. Cheap ones can't pass along
SMART diagnostics. My setup is below; the N40L can't run MacOS, but
I've used a Mac client to a Linux server for 15 years, before and
including MythTV. If you insist on MacOS on the server, you are better
off with either a Mac Pro with room for internal drives, or an
inexpensive NAS; either prebuilt like Synology
(<https://thewirecutter.com/reviews/best-network-attached-storage/>),
or something like FreeNAS. (Microservers are inexpensive on
Craigslist.)

[1] Yes, this includes those times when you run `fsck -fy` in Mac
single-user mode after an unclean shotdown
