Hi!

I'm running 10.13.2 and below is not fixed after upgrading to 10.13.3


When I eject USB flash, it disappears correctly in finder, disk util and terminal but after few minutes,
USB appears again like I unplugged it and plugged it again. (about 5~10 mins)

Tried to insert USB to computer directly, different slot or HUB but it works same way.

I did same test on MBP and iMac, I got same result so I guess it is OS feature or problem.

Did I miss something?

Thanks!
 
I just checked on my MBP 10.13.3 and this problem is not there, I suggest you erase this USB flash and test it again, and check for a virus or malware on your system which could cause this problem.

This looks like an image copy being made as a virtual volume.
The same technique is used when installing a *.dmg
I second the other responder as this looks like enemy action.
;JOOP!

I tried that but it doesn't work. (erase to different file system as well)
Maybe I need to try other USB flash.
Thanks for reply.

If it is because of virtual volume, can you say something I can try please?
After remounting (unintended), I still can access to flash so it may not be a virtual I guess?

You should apply DiskUtility to test the nature of the phantom volume.
It should be able to dismount it definitively.
