I have happily used UFSexplorer for several years. I use it to access mostly Linux and BSD formatted drives from various NAS boxes. It is available for Windows, Apple, BSD and Linux. The partitioning schemes accessible with it include FAT (all versions). NTFS for Windows, HFS+ for Apple, EXT2,3,4, ReiserFS, JFS, and XFS under Linux and both UFS and UFS2 under BSD. No plugins needed, nothing extra to buy except if you require access to RAID. Yes it will rebuild a RAID volume and allow you to recover things. While the RAID portion is an extra 25 Euros, the standard recovery software has come down form 55 Euros to 40 Euros. I paid the higher amount several years ago and feel well served by the value received.
The try before you buy thing here is to let you see what is there but is all look and no recovery. Pay to play but worth the money.
