There aren't half as many data recovery programs around for Mac as there are for Windows. Maybe that's because they are more stable in general but there are times when even Macs go wrong and you lose your data.
Disk Doctors Mac Data Recovery software recovers lost and deleted data from HFS+ and HFSX file systems on Mac OS X. Disk Doctors Mac Data Recovery is easy to use and supports both Intel and PowerPC based Macs. It works not only on your internal hard drive but also on any other external drives you've got attached to your machine. This includes Camera/Flash cards, Firewire drives, and USB drives although you are limited to certain brands namely LaCie, iOmega, Seagate, Maxtor and G-drive.
Installation requires your Mac user password as Disk Doctor needs access to libraries and files that may contain damaged data. It's very easy to use because on startup, you're presented with a list of connected devices which you want to scan. You can scan within certain folders or directories or choose to scan the entire drive. The developers claim that the difference between Disk Doctors Mac Data Recovery and similar products is that this app uses a non-destructive read only data recovery mechanism to recover lost data unlike other software that claims to repair your drive after data loss incident. You can preview files before you recover them to see whether its both possible and worth waiting for the recovery process to take place.
Disk Doctors Mac Data Recovery is an elegant and straightforward data recovery tool that could rescue your data if the worst happens.
