UFS Explorer RAID Recovery is great for responding to data loss challenges and is suitable for both commercial use in computer service centers and for home use. To recover lost data, you usually only need to connect the storage device to the computer and perform a few steps with the software. Support for almost any type of storage, including complex RAID storage allows you to solve most of these incidents.

If data has been lost from the NAS or RAID device, it should be turned off immediately. Then carefully remove the disks and connect them to the computer for data recovery. Data recovery requires simultaneous access to all drives on which the storage volume is created, so you need to connect all drives at once. Please note: if a disk has failed before and has not been used for some time, such a disk (usually!) should not be connected for data recovery.

If the condition of some disk is unsatisfactory or there is a risk of its degradation during operation, the program allows you to quickly and efficiently create an image of such a disk thanks to the presence of a professional-level disk imager tool. This tool allows you to efficiently handle data reading problems and allows you to quickly and accurately transfer data from the original device to the image. If some blocks cannot be read, the program saves a map of such blocks for the possibility of further diagnostics or adaptive data reconstruction.

The program works with disk images or virtual disks as efficiently as with original disks. Therefore, if you have disk images, it is recommended to use them. Due to the wide support of various formats, the program allows you to use images created by other (third-party) software.

If possible, the program automatically constructs data volumes both from individual disks and from RAID disk sets. Some technologies, such as Drobo BeyondRAID or LVM Thin Provisioning, require explicit assembly of volumes with the help of special tools available in the program. Additional tools also allow you to assemble volumes that for some reason are not assembled automatically.

Once the volume becomes available, the program automatically provides access to the files on it, without any scanning or analysis, just like the OS does. If you need to search for lost data or reconstruct the volume structure after damage, the software supports several types of quick and deep analysis (scanning) to search for lost data.

Finally, when the desired data is found and is available, you can view it in the interface, perform the necessary searches or sorts, and then copy the found data to a new storage.

Key features

Efficient data recovery from RAID Efficient data recovery from RAID
UFS Explorer RAID Recovery allows working with RAID of various levels, including standard patterns (RAID 0, RAID 1, RAID 1E, RAID 3, RAID 5, RAID 6, etc.), nested levels (RAID level 10, 50, 60, 50E, etc.) as well as custom RAID configurations via RDL or Runtime VIM. The software also supports specific RAID types, like Drobo BeyondRAID, Synology Hybrid RAID, Btrfs-RAID and RAID-Z which makes it an essential tool for most tasks related to data recovery from complex storage systems.
Support of various file systems Support of various file systems
Besides RAID, the software offers direct access to the intact content and performs data recovery from other common types of storage media, including internal and external hard drives, USB flash drives, memory cards, etc. used in different environments: Windows (FAT/FAT32/exFAT, NTFS and ReFS/ReFS3), macOS (HFS+, APFS), Linux (Ext2/Ext3/Ext4, ReiserFS, XFS, JFS, IBM JFS2) and BSD/Solaris (UFS/UFS2, ZFS).
Perfect for data recovery from NAS Perfect for data recovery from NAS
UFS Explorer RAID Recovery supports popular NAS devices of such vendors as Drobo, Buffalo Technology (TeraStation, LinkStation), Synology, QNAP Systems, etc. and is an optimal solution for this type of storages. The software detects RAID metadata on NAS drives and uses it for automatic reconstruction of the storage. The array can also be assembled manually with the help of an embedded virtual RAID builder instrument.
Work with diverse storage technologies Work with diverse storage technologies
Along with RAID-based storages, this specialized application offers the possibility to handle other storage technologies implemented in modern devices. Among them are Windows Dynamic Disks and Storage Spaces, Apple Software RAID and APFS-based Fusion Drive, Linux mdadm and LVM, virtual disks used by leading virtualization systems, including VMware, Hyper-V, VirtualBox, QEMU and XEN, as well as a variety of disk image formats.
Extensive disk reading and imaging possibilities Extensive disk reading and imaging possibilities
UFS Explorer RAID Recovery allows choosing the method of data access and specifying a timeout for cases when reading fails due to an I/O device error. An advanced disk imager makes it possible to customize the imaged area and provides adjustable parameters such as read timeout, block size, direction, protocol and settings for the omission of defective blocks. The bad blocks encountered during the process of imaging get indicated in a map which can be utilized for other data recovery operations.
Adaptive RAID reconstruction Adaptive RAID reconstruction
The software supports an adaptive reconstruction of redundant disk arrays (RAID 1, RAID 5, RAID 6, etc. ) using bad sector maps generated for the components during the process of their imaging or through recognition of a given pattern and external ones created by other compatible tools. The program determines damaged data blocks on disks on the basis of their maps and can restore them using redundancy (parity information or a copy of data).
Customizable scanning Customizable scanning
The software offers several scanning options, including a quick scan for defined file system types, longer profound search for lost data by known content with the possibility to provide custom IntelliRAW rules, scanning of the space used by the file system or just the “free space” areas. The scanning procedure can be paused for checking the intermediate result while its results can be saved for further references.
Defining damaged sectors Defining damaged sectors
UFS Explorer RAID Recovery produces defects maps during disk imaging and supports ones created by other compatible solutions. The program can utilize such a map for the virtual definition of damaged sectors on the storage or identify bad blocks dynamically by recognizing a specified content pattern. The defective areas can also be masked with a provided text or hexadecimal template.
Helpful additional options Helpful additional options
UFS Explorer RAID Recovery is enhanced with a set of helpful options for increased convenience. The software makes it easier to process the results through visual differentiation between the currently available and restored data, shows the state of each recovered file, offers an advanced search function, allows previewing found files of most common formats, including images, PDF documents and text files, sorting files by name, size or date and filtering them by different criteria.

It allows processing composite volumes, including LVM, MS Storage Spaces, Dynamic Disks, Apple Software RAID and APFS-based Fusion Drive, etc. which significantly expands the list of target devices it can be applied to.

Retrieve files from disks or RAID with bad sectors

The application gives the possibility to recover data from storages that have damaged sectors or other hardware issues with maximum efficiency. Not only it offers highly configurable disk reading and imaging procedures but also generates a map of bad blocks during the imaging process. In addition, virtual bad blocks can be defined dynamically on disk images by recognizing a given pattern or by reading bad sectors maps created by other compatible solutions.

Open or recover data stored in virtual machines: VMware, Hyper-V, VirtualBox, etc.

UFS Explorer RAID Recovery effectively deals with disk images and virtual disks created by major virtualization software, like VMware, Microsoft Hyper-V, VirtualBox, QEMU, XEN, etc. and successfully copes with data recovery from such storages as though they were ordinary physical devices.

Reconstruct damaged file systems: Windows, macOS, Linux

A set of tools integrated in the software allow effectively solving practically any case of logical data loss, including the most severe ones. The program will either simply read file system metadata or conduct its detailed analysis and predict the allocation of files based on the file system specifics, allocation of other files or file content analysis to produce the best possible data recovery result.
