Today I helped a customer that was using Data Rescue 3 to recover data from an external hard drive that he could not access. He had ran a Deep Scan on the drive and had recovered some of the files but when he went to open the files he would get permissions errors. This can happen when the original drive was experiencing file ownership or permissions problems.
I guided him to the Data Rescue 3 Recovery Preferences in the Scan Engine tab where he could edit the Change ownership and Permissions promotion settings to “For all items”. By changing these settings it will make sure that he has ownership and permissions for all of the files that he is recovering. After he attempted the recovery again he was able to open his files successfully and was very happy to have his files back.
