Recover Deleted Files on Mac with Data Recovery Software for Mac OS X

The first thing you should remember about removing the item on Mac is that dragging it over Trash deletes the file temporarily. In spite of the fact you don't find the entry for this file on the disk directory anymore, you still can restore it.

Note however, that the space that was once taken by the item is now labeled as "vacant" by the system. So, if you save new data to the drive, the recovery process will be somewhat more tricky.

So, tip #1 if you have deleted a file accidentally and would like to recover it: don't write anything new to the disk where the item in question was located. Ideally don't access this disk at all.

The second way you might have deleted a file is using 'Erase a drive' option of Apple's Disk Utility. Not the worst case if you haven't changed the default setting, which performs 'Quick Erase'. That operation rewrites the new empty disk directory over an old one. As a result the contents of the old directory stays intact and can be 'brought to life' unless it was written over.

Another option offered by Apple's Disk Utility is 'Secure Erase'. To tell the truth, it's the last thing one should use if there is a slightest chance that the data might be needed later on. There is no third-party tool which would be able to recover the data once this operation was applied.
