Diskmanagement.disenter error 49218​

external drives sporadically refuse to mount.
when trying manually in the diskutil, this is the error I get.

happening on various OS- and CPU-versions with various apfs-disks.
solution: reboot.

discomforting. annoying. especially since os-shutdown takes ages when this happens.
since macos11.
**** like that should be fixed!!!
an os that cannot reliably deal with mass storage is just about dead.

tons of threads about this can be found, no proper solutions though.
like here: https://developer.apple.com/forums/thread/695361
anybody knows what's going on?

Don't use APFS if you don't have to.
It's bad

hey bogdanw, thx for your reply.

you mean generally on ext. hd-drives?

what is apfs meant for, then? just internal ssds?

or do you advise against using apfs altogether?

wasn't apfs sold as the new filesystem for all?
and if so, are they working on fixing it?

the timemachine forces apfs conversion also on hdds, right?

macOS can now only be installed on APFS.
I don’t use TimeMachine, I don’t know what it requires.
I use external drives formated as HFS+ (Journaled HFS Plus) for macOS and as ExFat for macOS, Windows and Android.

Well, one can never tell what Apple means, ha ha, but I don't think its meant only for internal SSDs. I've seen nothing to indicate that.

In recent versions of macOS (I think beginning with Big Sur?), if you tell TM to back up to a "new" disk (one that doesn't have a pre-existing TM backup on it), then yes, TM will re-format the drive as APFS, no matter what format you had used to initialize it. Both SSDs and HDDs will be reformatted to APFS in this case.

If you tell TM to back up to a HFS+ disk that has a pre-existing TM backup on it, then TM will continue to back up to that HFS+ formatted disk. That's what I've read, anyway -- I haven't tried it.

can I ask you what you use for backups then?

Copy-paste. I copy the files/folders to an external drive.

 

[elgato2024]

that's it?? what, in finder?
any reasons why you use no backup software such as carboncopycloner?
