If you are recovering from your Mac’s internal hard drive, then save the application to an external hard drive or USB flash drive, in order to avoid overwriting any data. To do this, download Disk Drill to your MacBook as you normally would from the CleverFiles website, double-click the disk image and then drag the Disk Drill icon to your external drive. If you are not recovering files from your internal hard drive, then you can drag the icon to your Applications folder.
Disk Drill offers outstanding protection features that protect your files and prevent any possible data loss. S.M.A.R.T. Monitoring option always keeps an eye on your hard drive for any signs of malfunctioning. Guaranteed Recovery saves invisible copies of any trashed files so that they can be recovered whenever you need. Recovery Vault keeps all metadata save in order to restore files with their names and locations.
It will go deep into details and structures with the help of Deep Scan even when the situation seems hopeless. Disk Drill scans raw data on your hard drive (NTFS, FAT, or else) and is searching for a binary signature of the file. Once the app can collect the found fragments into a structure and file signature is recognized, files like XLS, DOC, AVI, MP4, JPG, etc. are recovered faster.
