How to Recover Lost Data on OS X Mavericks

When Disk Drill recovers your files, we recommend that you save those files to a separate disk. So you will need to have enough room on your Mac’s internal drive, or connect a second external drive to recover the files to.

Connect your hard disk that was damaged during the Mavericks upgrade to your Mac. Connect a second drive to copy the files to, if needed. Then launch the Disk Drill app.

Once you launched Disk Drill, a list of available disks will be shown. Click the name of your corrupted external hard drive to select it. Now select a scanning option. Most probably the lost partition will have a generic name instead of the correct one that was used before the data loss. If the button to the right of the partition name says “Rebuild” it means that the drive is not mounting properly. Click “Rebuild” to rebuild your directory and mount the disk. It will then automatically complete a Quick Scan of the disk. If the button next to the drive name says “Recover” it means that your drive is mounting OK. In that case, you can go straight to scanning. Simply click the drop-down arrow next to “Recover” and choose “Quick Scan”.

Once Disk Drill is done scanning, it will display all the files it has found. Review these files to be sure all of your data is there. If you haven’t made any repair attempts on your drive since your Mavericks upgrade, we anticipate all of your files will be in good shape. However, we do recommend that you preview key files (by clicking the “eye” icon next to the file name) to be sure that they are not corrupt. And if you did make any rescue attempts prior to using Disk Drill, then you should definitely preview your files.
