How to Recover files on Mac OS X Yosemite

Next to the volume you wish to scan, click the “Recover” (or “Rebuild”) button. Disk Drill will do a complete scan of the volume, proceeding with each of its scanning algorithms one by one.

If Disk Drill finds a lost partition, it will list the recoverable data of this partition in the scanning results, and you just need to choose a destination drive for data recovery Mac Yosemite. Alternatively, if the lost partition can be rebuilt using HFS+ Catalog Rebuild algorithm, the corresponding option will appear in the disk list, and you can go ahead and click the Rebuild button. If the rebuilt file structure looks correct, you can either copy the data by mounting the partition as a virtual disk, or just go on and write the repaired catalog to the source drive.

If you’re looking for files, not partitions, you can review the list of files that Disk Drill recovered during its scan. The files may not have their correct filenames, so you may need to preview each one by clicking the preview (eye) icon. You can narrow your search by sorting the files by size, date and file type. Once you have found your lost data, you can proceed with upgrading to Disk Drill PRO and recovering your files.
