R-Studio unformat tool
can analyze and unerase data from software RAIDs and volume or stripe sets.
R-Studio detects and processes
hardware RAIDs and volume or stripe sets like regular drives/volumes.
Hardware/software RAIDs
can be searched for files or scanned. Found
files can be recovered the same way as from regular drives/volumes.
R-Studio supports four major algorithms for the placement of segments
among the disks in the array: Left Synchronous, Left Asynchronous,
Right Synchronous and Right Asynchronous.
If, due to data loss, a system does not recognize a software RAID, but
such RAID did exist, and the information on what hard drives were in
the RAID is available, a Virtual volume set or RAID can be created and
processed like a real software RAID. Such Virtual volume set or RAID
may also be used to unerase data from hardware RAIDs and volume or
stripe sets if their controllers do not work properly.
If a partition from a hardware or software RAID and volume or stripe
set is absent, due to hardware failure, for example, empty space may
be added to the Virtual volume set or RAID in order to correctly
re-construct its structure.
R-Studio unformat tool
does not write anything real on disks. Empty
spaces and Virtual volume set or RAID are pure virtual objects that do
not affect actual data on disks.

R-Studio,
R-Undelete and
R-Linux
can create an image file of any object they can recognize. Images are very useful if there is
a risk of total data loss due to hardware malfunction. If bad blocks are
constantly appearing on a hard drive, the only way to save the data is to
immediately create an image of that drive. All data search, scan, unformat, unerase and recovery
can be done from this image.
R-Studio and R-Linux can create image files for an entire hard
drive, logical disk, or its part. R-Undelete cannot create image files
for a hard drive, but can create image for logical disk, or its part.
All images have the same format. This means that an image made by R-Undelete,
for instance, may be opened and processed by R-Studio.
