Volume Sets and RAIDs

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 on the Device/Disk 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 hard 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 software volume set or RAID.

To create a Virtual volume set or RAID

Click the Create virtual volume sets or RAIDs button or the Create menu to create a Virtual volume set or RAID

‚	Select an appropriate type from the shortcut menu

Ü	A Volume sets and RAIDs object will appear on the Device/Disk panel

ƒ	Drag the required partitions from the Device/Disk panel to the Parents tab

Note: Partitions should be placed in the same order as they were in the original volume set. If this order is incorrect, you must change it by dragging the parents in the correct order. Moreover, the RAID block size parameter must be set the same as for the original volume set. If the order or "Raid block size" parameter is not correct, data on the parents will not be damaged, but they cannot be recovered.

Note: You may check how correctly you have reconstructed the original volume set or RAID. Scan it, and if an unusually large number of recognized partitions have been found and their offsets differ by block size multiples (for example, 32KB or 64KB), something is wrong in the parameters of the created Virtual volume set or RAID.

Ü	The Virtual volume set or RAIDs object can now be processed like regular drives/volumes

Empty space objects

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 empty space in order to correctly re-construct the hardware volume set or RAID or software volume set or RAID structure. The empty space should be of the same size as the missing partition and placed in the same place.

Note: R-Studio does not write anything real on the disk. Empty spaces are virtual objects that do not affect actual data on the drive.

To add an Empty space object

Select a Volume sets and RAIDs object on the R-Studio's Device/Disk panel

‚	Right-click in the Parents tab in the right pane and select Add Empty Space on the shortcut menu or select Add Empty Space in the Create menu and specify size for the Empty space object

Ü	An Empty space object will appear in the Parents tab

ƒ	Drag this object to its correct position

Ü	This Virtual volume set now can be processed like a normal drive/volume
