The HFS+ partition on attached USB drive is not compatible with Lightning Server


The partition of the USB drive you have plugged is in Mac OS X HFS+ format but it is not compatible with Lightning Server. It is very rare to see this error message as Lightning Server is compatible with both journaled and non-journaled HFS+ partition.


  • Re-format the USB drive on a Mac computer.
  • Please consider to use another partition format, such as exFAT or NTFS.
