Disk Warrior and Disk Utility (Repair Disk and its cousin fsck) can repair a directory of a healthy hard drive. Prosoft Data Rescue with an external Firewire hard drive of greater size can recover information from a dying hard drive as long as the directory is in good shape. As such, not having a backup would leave you in a catch-22 situation if both the directory and the hard drive are in bad shape, leaving you only with a data recovery firm (see my aforementioned backup your data link for more info on data recovery). A dying hard drive and a damaged directory can have identical symptoms. Given those exceptions visit these sections to find the type of repair you need to perform:Ĥ. You can't repair permissions while booted from CD, except in Mac OS X 10.4 or later. You must boot off a CD, or connect the drive via target disk mode that you wish to repair the directory of.ģ.

Issues which require software based repair frequently appear to have the same symptoms as a dying hard drive.Ģ. You MUST backup your data prior to repairing anything. Important exception notes many people forget:ġ.
