UFS Explorer Professional Recovery is a full-featured software application created exclusively for data recovery specialists. The application successfully combines low-level data analysis and data management functions with high-level data recovery tools. UFS Explorer Professional Recovery is the only software of the UFS Explorer group which allows altering original information on the storage.

An advanced multi-tool interface makes the software appropriate for even complicated data recovery tasks. UFS Explorer Professional Recovery enables thorough data analysis and full-scaled data recovery. Embedded RAID-Builder mechanism allows building standard RAID configurations of any level. Moreover, 'RAID definition language' used by the software lets you build any custom RAID configuration. If necessary, low-level tools of UFS Explorer Professional Recovery allow making permanent changes to the information initially contained on the storage. The software can be installed in several operating systems – Microsoft Windows, Apple Mac OS and Linux.

Aiming at user-friendliness software tools are grouped into several separate blocks each applicable to certain operations. Disk management system automatically defines storages and opens disk images, both standard and custom RAID configurations as well as virtual disks of virtual machines. The system lets you open a disk partition or a storage device specifying the name or the mount point (disk letter, mount path etc.). UFS Explorer Professional Recovery includes embedded Hex-Viewer tool which allows viewing data on a disk or separate disk partition and altering including overwrite data on the storage. File manager allows the user to preview existing file system and recover data from it. Other functions of the file manager include: files search and preview, data analysis, identification and positioning by file content and file descriptors. The file system recovery manager allows finding files, previewing found files and recovering them to a local disk. For added convenience UFS Explorer Professional Recovery manages simultaneous performance of multitasking operations.

Created for professionals the product requires at least basic user experience. The software contains a set of safe read-only data analysis tools allowing users to solve most practical data loss cases and a write-enabled hexadecimal editor to correct even severe cases of file system damages.

As a comprehensive multi-functional application UFS Explorer Professional Recovery is a perfect solution for detailed data analysis and professional recovery of lost and deleted data.

Key features

Immediate data access for consistent file systems

The software allows users to access data on all the supported file systems, including file systems on disk images, virtual disks, RAID storages etc. without the need of prior scanning.

Support of disk images and virtual disks

The software allows opening disk images and virtual disks produced by virtual machines of the leading virtualization software retailers (including VMware Player, VMware Workstation, VMware ESX Server, VMware Fusion, Microsoft Virtual PC, Microsoft Hyper-V, Parallels Desktop etc.). The software operates virtual disks and disk image files exactly as if they were physical disks and allows users to access or recover lost data from disk images and virtual disks.

Recovery of complex RAID storages

The software release for professional data recovery supports virtual reconstruction of a RAID system after failure of controller or RAID metadata. The software manages virtual RAID building and reading its files and folders as if it were physical RAID storage. This professional application easily handles both simple RAID configurations (such as stripe set - RAID level 0, Span, Mirror - RAID level 1) and complex RAID such as RAID 5 and RAID 6. RAID-on-RAID feature allows building RAID configurations of increased complexity such as RAID 50, RAID 60 etc. Support of Runtime Software Virtual Image Files together with RAID Definition Language enable setting up custom RAID configuration with different data distribution algorithms. Asynchronous data access technology and adaptive RAID reconstruction make recovery fast and efficient.

Full-disk encryption support

The software is able to decrypt disk volumes for data recovery and on data access purposes (if encryption key is known). Decryption module is compatible with Linux device mapper encryption module (dm-crypt) and can be used with encrypted storages (including NAS storages).

Disk-on-disk recovery

The software opens disk image files or virtual disks from a file system opened in UFS Explorer. The application allows users to easily build RAID storing stores VMware ESX virtual machines (VMFS file system), open virtual disk directly from VMFS and recover data directly from virtual machine without the need to extract virtual disk first. Disk-on-Disk software feature activates a variety of low-level data access tools such as access to virtual disks locked by Hyper-V server, access to CD/DVD image files stored on a file system of 'parallel' operating system etc.

Comprehensive files recovery

A set of tools integrated in the software provides solutions for the most common data loss cases. Depending on certain situation the software either simply reads or conducts detailed analysis of file system metadata to finds lost files. Even if the metadata is permanently lost, the software can predict the file allocation basing on the file system specifics, other files allocations and file content analysis to produce the best possible data recovery result.

Recovery after file system format

UFS Explorer Professional Recovery allows users to analyze the storage for previous file system formats and even choose among different possible file system configurations for recovery. If the file system of the storage before formatting is unknown, the software can analyze the storage and find all the possible file system variants. The software finds all detectable file system variations and allows users to choose all or any of them for recovery.

Data consistency analysis and error correction

UFS Explorer Professional Recovery is the only version of UFS Explorer group which includes tools for low-level data consistency analysis. The software allows identifying location of file/folder descriptor, its contents, map of file/folder fragments and navigating among them. If file contents are faulty, UFS Explorer allows navigating through file fragments, finding the faulty one and correcting it. Write-enabled hexadecimal editor enables correcting minor and moderate file system damages (fix directory entries, move superblocks, fix inodes and so on) in order to return file system back to the consistent state.

Software testing and certifications
