• Does anyone have experience with data recovery or directory repair tools such as DiskWarrior or Disk Drill? Got an external drive with 1.5TB of data on which won't mount, so disk Utility can't repair it. Done a scan with the free version of Disk Drill and the data's there, so wondering whether to upgrade so I can recover it - or whether DiskWarrior's partition wizardry is the better approach.
