ZAR is a powerful data recovery solution that can recover all kinds of files from FAT, NTFS, XFS, and ext2/3/4 volumes. Supports native NTFS compression. Working from within Windows XP/Vista/7, ZAR can recover simple volumes or those located on RAID0, RAID10, or RAID5. ZAR also includes free digital image retrieval feature and an automatic scan for partitioning information. Zero Assumption Recovery works in read-only mode, which means that it does not modify the affected drive and thus there is no risk of incurring any additional damage. A small drawback of this approach is that you have to have another data storage (typically another HDD) available with which to transfer your data.
