UFS Explorer

The entry point into the family: deleted files, formatted drives, and RAW partitions on a single disk. Broad file-system coverage, no RAID reconstruction — that's what the tier above adds. It's not a bare-bones tool despite the "entry point" label: a built-in disk imager with multi-pass reading and configurable bad-block handling, bad-sector mapping, virtual-disk support (VMware/Hyper-V/VirtualBox/QEMU and others), and a hexadecimal viewer for storages, partitions and files all come standard.

• File systemsNTFS, APFS, Ext4, Btrfs, ZFS, XFS, FAT, UFS, JFS, ReiserFS
• Also includedDisk imaging with bad-sector maps, virtual-disk support, hex viewer
• RAID supportNone — single-disk only
• LicensePerpetual, sold per OS (Windows/macOS/Linux purchased separately)

Everything in Standard Recovery, plus RAID and NAS reconstruction — including automatic assembly when usable metadata is present and a manual RAID Builder for cases where parameters must be supplied or corrected. Per SysDev's current product documentation, RAID types run from standard levels (0, 1, 1E, 3, 5, 6, 7) through nested/combined ones (10, 50, 51, 60, 61, 50E) to proprietary layouts — Drobo BeyondRAID, Synology SHR, Btrfs-RAID and ZFS RAID-Z (Z1/Z2/Z3). Recognized NAS vendors number over 50, including Synology, QNAP, Drobo, Buffalo, Asustor, TerraMaster, Western Digital, Netgear ReadyNAS, Thecus and Seagate Business NAS. It also covers Linux mdadm/LVM (with thin provisioning) and Btrfs-RAID, Windows Dynamic Disks and Storage Spaces, Apple Software RAID and APFS Fusion Drive, and BitLocker and APFS encryption.

• AddsRAID metadata detection, automatic and manual array assembly, 50+ NAS vendor layouts, BitLocker/APFS encryption
• RAID supportStandard, nested and proprietary RAID (Drobo BeyondRAID, Synology SHR, Btrfs-RAID, ZFS RAID-Z); mdadm, LVM, Storage Spaces, Dynamic Disks, Apple RAID/Fusion Drive

Includes the RAID Recovery feature set and adds distributed recovery when array members are attached to multiple computers on a LAN. This is not "NAS recovery over the network" in the remote-scan sense some consumer tools offer — it's genuine distributed source access for RAID reconstruction: the array's member disks can remain physically attached to different networked machines and still be accessed as components of one virtual reconstruction, avoiding the need to connect every source drive to a single workstation.

The forensic/lab-grade edition: VMFS and other virtual-disk formats, LUKS-encrypted volumes, E01/AFF4 forensic image formats, a built-in hex editor, and SAN support — aimed at a working lab, not a one-off personal recovery.

• PlatformsWindows, macOS, Linux
• AddsVMFS/LUKS, forensic image formats, hex editor, SAN support
