Recommended data recovery programs (DiskTuna Approved):
UFS Explorer
Very well rounded tool supporting many filesystems and advanced storage technologies such as RAID and numerous encryption techniques. Moderately difficult to use. This is your best bet when trying to recover data from NAS devices.
[Mac/Win/Lin]{FAT|NTFS|ReFS|HFS+|APFS|EXT|BTRFS|UFS|XFS|ZFS|+More +RAID}
R-Studio
Well rounded tool with a good mix of filesystem, RAID, and encryption support. Supports professional data recovery hardware from DeepSpar.
[Mac/Win/Lin]{FAT|NTFS|ReFS|HFS+|APFS|EXT|UFS|XFS|+RAID}
DMDE
Another favorite for some pros. This is my work horse logical data recovery tool. Be warned that this tool can write to patient drive, but it will never do so using the default configuration.
[Mac/Win/Lin/DOS]{FAT|NTFS|ReFS|HFS+|APFS|EXT|BTRFS|+RAID}
Note EXT = Ext2/3/4, FAT = FAT12/16/32/exFAT
