Open Terminal and type in this command in the text window.

The same place is also the 'Terminal' and application you need to enable the advanced features of Disk Utility. This will allow you to do search and rescue operations on hard disks.ĭisk Utility is in the Utilities folder in your Applications folder. If you don't understand the purpose of disk images - or you have lost important data, I recommend using a data recovery service like DriveSavers Making Raw Disk Copies in Disk Utilityĭisk Utility can copy the raw contents of a hard disk into a disk image.

Downloading software, and putting new data on your disk, will have a chance of writing over the things you wish to recover. The more files you save on your Mac after you have lost files by accident, the less likely it is that you can recover the images (or other lost files). Note: This procedure is not recommended if you have lost data on your Mac and you do not have an extra hard disk. To work with entire hard drives you will need enough disk space to hold a complete copy of the disk you are making a copy of, and space enough left to save the images/data you recover. File Juicer can search disk images for data - just like any other kind of file.
