R-Studio
Originally developed for use by data recovery experts, R-Studio is a powerful set of tools for recovering files on Windows, Linux and Macintosh systems. (The Mac version is a separate product).
R-Studio works on local and network disks even when partitions have been formatted, damaged or deleted. One of its strengths is RAID recovery: it treats hardware RAIDs like ordinary drives and volumes, and its "unformat" tool recovers data that have been erased from software RAIDs. Other products from the same vendor include the inexpensive R-Undelete, a file undelete solution for Microsoft's FAT (File Allocation Table) and NTFS (New Technology File System) file systems.
R Studio can handle FAT12, FAT16, FAT32, NTFS, NTFS5, and EXT2FS file systems. It can recover data even if FDISK or other disk utilities have been run, if a virus has invaded, if the FAT has been damaged or the Master Boot Record destroyed.
Comment
Whether you simply want to undelete a few files or recover data from a seriously damaged hard disk, perhaps even a RAID array, R-Studio can help. It has a clear, Explorer-style interface, gives full details about every file it recovers, and makes a good job of recovering pictures.
Independent reviewers and users have tested it and praised it very highly, especially when it has rescued them from serious data-loss situations. The developer has published a detailed technical article called "Why R-Studio?" that makes an eloquent case for using it.
