A2zDataRecovery

Unitrends has been offering private cloud-based disaster recovery, in addition to disk-based all-in-one on-premise data protection appliances. Colocube has an infrastructure for delivering 24x7x365 services. Together, the companies will now offer 24/7 cloud-based disaster recovery solutions to small and medium enterprises.

Diskinternal's Efs Recovery is reported to be a tool that can recover information from encrypted volumes located on corrupted, formatted or inaccessible partitions under Windows 7. The tool can also recover information from damaged and repartitioned hard drives.

Hard drives are mostly electromechanical equipment (though solid state drives are now coming to the market) and cannot but fail sooner or later. The issue then will be whether you had prepared for the crash by regularly backing up all important data to a secondary location.

There are a number of data recovery tools for the Mac. The important thing is to select the tool that is right for the specs of your machine and also the the specific data you want to retrieve.

As has been mentioned on other posts, "deleted" files are not actually deleted from the disk. Instead, Windows mark the Master File Table (MFT) entry for that file as deleted. MFT entries are like Table of Contents of a book; they point to the storage locations of the content of the disk.
