com.apple.DiskManagement.disenter error 0 on external drive

Arguably, "figured it out myself" is not a very helpful answer to a situation like this, as people looking for answers reach a dead end.

Anyways, if your disk happens to be ExFAT, and you remember improperly removing the disk the last time you used it, chances are, fsck is holding it hostage (metaphorically, of course). fsck is trying to repair the disk, but it will stall forever, so you want to launch Disk Utility, and the Terminal. Try to mount the disk, and switch to Terminal and write sudo pkill -f fsck. The disk will mount in read-only mode, and from there, you can repair it with First Aid in Disk Utility. This won't work for non-ExFat drives, as macOS manages them differently.

This solved my problem thanks. Just a note to future users, the repair took a really long time for my 5TB drive. Be patient.

This happened for me on a Big Sur MacOS, clicking the 'First Aid' option in Disk Utility kept giving me this same error. What ended up working for me was restarting my laptop, then continuously trying 'First Aid' until one time it suddenly didn't give me the error, and after waiting about 20minutes the drive mounted properly. I don't think I did anything differently other than trying over and over again.

Thanks jkrosado!

Thanks @jkrosado

Just to note to @jkrosado instructions: it worked with Mac OS Extended drive format too.

@jkrosado tysm!! it worked for me and saved me from panicking due to all my homework and software I need for my classes in that hard drive

This still isn't working for me. I don't understand what this "and the Terminal" means. When I try to mount my drive, the error that is the title of the forum comes up and it appears I am at a dead end. I tried to repair the drive, and it seemed to do something (with a bunch of green check marks) saying it was fixed, but it still won't open or be recognized by my finder or desktop. If anyone is able to walk me through this, I would be very appreciative.

I also got this working on my HFS+ drive. Worked exactly the same as an ExFAT not sure what the technical background on this is but for those wondering.

Thanks @jkrosado Your answer was helpful. Drive should be ExFAT and it worked after killing process and first aid.

Thanks!

My external ssd (Apple 251GB, APFS formatted) doesn't show up on the desktop. It is visible in Disk Utility but I can't repair, erase or split it. Does anyone have advise for this issue?
