Disk Utility Cannot Verify a RAID Volume

Last updated 2012-07-10 - Send Feedback
Related: Apple macOS, RAID

Status: NOT fixed as of Mac OS X 10.7.4.

This kind of inattention to details shows Apple’s cavalier approach to system updates— exercise care when upgrading to a new Mac OS X version. See also how Apple simply removed a drive API without warning, and in a minor release!

RAID volumes created with Disk Utility cannot be verified by Disk Utility.

You cannot make this stuff up. Disk Utility simply does nothing when the Verify or Repair buttons are clicked.

See the command line (Terminal) method to verify a volume.
