If you need advanced file recover, Mac Data Recovery Guru 2.0 is an app you’ll want to check out. It requires Mac OS X 10.6 or higher, costs US$99 and is available at http://macosxfilerecovery.com (a limited version can be downloaded for free).
Mac Data Recovery Guru lets you “resurrect” deleted files. It can find files lost to faulty drives, even those suffering from the “click of death.” The interface lets you browse deleted files, and recover them by file type. Simply click on the lost file and it will show a preview of the contents. Click recover to save it. The only thing that can stop Data Recovery Guru 2.0 is when: a) a file has been overwritten or b) secure delete has been used.
Mac Data Recovery Guru will work on drives with failing motors or the click of death. The software simultaneously provides a surface scan and a bad sector count (if appropriate). Media including flash drives, hard drives, CDs, DVDs, SSD drives and all types of memory cards is supported. If Disk Utility can see the drive, the files can probably be recovered.
The software works with all Macintosh disks (HFS filesystems, HFS+, HFSX filesystems), Windows disks (NTFS, FAT filesystems), Linux disks (Ext2, Ext3, Ext4 filesystems), Unix disks (XFS, UFS filesystems). Data Recovery Guru 2.0 will get data fragments of any kind of data and provide it in a variety of formats (such as any raw text embedded anywhere on a system, or jpegs embedded in PSDs, etc).
Data Recovery Guru works seamlessly and has a short learning curve. Like the best Mac software, it’s intuitive and simple.
