I helped a customer today who’s MacBook Pro was no longer able to startup into Mac OS X. He decided to try the free trial of Data Rescue 3 to see if he could recover the data from his Macintosh HD since he did not have a backup. He was not sure what scan to choose in Data Rescue 3 so he contacted support for assistance. I suggested that he try a Quick Scan first, this will scan the existing file directory and typically takes a few minutes. The Quick Scan should be tried first if you have a start up drive that fails to boot to the operating system or an external drive that fails to mount.
When the scan finished, he went to the Scan Results which showed his Macintosh HD volume with the original folder structure and original file names. He was excited to see all his files, waiting to be recovered, so he purchased a license code and entered that into his free trial, which unlocks the software to allow for the recovery. He was then able to recover all of his files to an external drive and was very relieved to have all of his files in tact. Many times when you have a non-mounting drive the volume is corrupted and the directory structure is lost along with file names. It is still a good idea to try the Quick Scan in Data Rescue 3 first to see if the file directory is detected and if these files can be recovered and opened. If the Quick Scan doesn’t work, we would then suggest trying the Deep Scan and recovering the raw data.
