FIXED! - Could not mount “External Drive”. (com.apple.DiskManagement.disenter error -119930873.)

Just wanted to give a fix to a problem I didn't find n answer to here, maybe someone had it..


  1. Woke up, wanted to start work then I saw that all my external drives where offline.
  2. Went to Disk Utility, tried to mount them. This error appeared. (Could not mount “External_SSD”. (com.apple.DiskManagement.disenter error -119930873.))
  3. Freaked out - didn't push my latest work to git last night.
  4. Thought about programs that could interfere with disks, I have 2: NTFS for Mac and ESET antivirus.
  5. Remembered I played with the antivirus security settings. (Late last night).
  6. Unticked "Removable media blocking".
  7. Win.


Hope it helps someone.
