R‑Studio detects and processes valid hardware volume sets and RAIDs like regular drives/volumes.
R‑Studio can analyze and recover data from software volume sets and RAIDs . If a software volume set or RAID is present in your system, R‑Studio detects it, and a Volume sets and RAIDs object appears in the Drives panel. This object can be searched for files, scanned, and files found on it can be recovered the same way as from normal drives/volumes.
If, due to hardware failure, a hardware volume set or RAID cannot be accessed, or due to data loss your system does not recognize a software volume set or RAID , and you know what drives were in it, you may create a Virtual volume set or RAID and process it like a real software volume set or RAID or hardware volume set or RAID .
You may find more information on RAID types in our article What is Hardware RAID .
You may turn numerical indexes for objects to distinguish them better while creating virtual RAIDs.

Managing your own RAID layouts
To save your own RAID layout in the presets
|1||Click the More... button on Parents tab and select Save on the shortcut menu.|
|2||Specify the name for the configuration on the Preset name dialog box.|
|>||The new RAID configuration will be saved in the presets|
The configurations are stored in the user's RAID layout file . The path and name for this file is specified on the R‑Studio Settings dialog box. If no file is specified, R‑Studio will ask you to enter the name.
Loading your RAID configuration
If there're objects in the Parents tab, the preset will be applied to them. If the Parents tab is empty, R‑Studio will search the drives listed in the Drives tab for the parents in the user's RAID layout file . If the search fails, R‑Studio will show the Reference Parents not found message.
To load your RAID configuration
|1||Click the More... button on Parents tab and select the preset you want to load|
|>||The new RAID configuration will be loaded|
To edit your own RAID configuration
|1||Click the More... button on Parents tab and select Edit... on the shortcut menu|
|2||Select the required configuration on the Edit Block RAID Layout Presets dialog box.|
|3||Edit the parameters of the configuration and save it|
|>||The new configuration parameters will be saved.|
Turning Drivess On-Line and Off-Line on-the-fly
You may turn the objects in the virtual RAID or volume set on-line and off-line by selecting/clearing the checkbox on the Parents tab. It may be useful, for example, if you need to see which drive is non-actual in a RAID 5.
Actually, when you turn an object off-line, R‑Studio substitutes it with a Missing Drive or Empty Space object.
Missing Drives and Empty Space
If one partition from a hardware volume set or RAID or software volume set or RAID is absent, due to hardware failure, for example, you need to add a virtual missing drive or empty space in order to correctly re-construct the hardware volume set or RAID or software volume set or RAID structure. The missing drive/empty space should be placed in the same place as the missing partition.
Note: R‑Studio does not write anything real on the drive. Missing drives/empty space are virtual objects that do not affect actual data on the drive.
To add a Missing drive/Empty space object
|1||Select a Volume sets and RAIDs object in the R‑Studio's Drives panel|
|2||Right-click in the Parents tab in the right pane and select Add Missing Drive or Add Empty Space on the shortcut menu or select Add Missing Drive or Add Empty Space o n the Create menu. Which object type is necessary, R‑Studio decides automatically.|
For the Empty space object, Specify its size on the Add Empty Space dialog box.
|>||A Missing Drive or Empty Space object will appear in the Parents tab|
