It is commonly known, that every disk storage has its own properties, such as type, size, model, retailer etc. This information resides inside the disk and is usually programmed by the disk retailer with a slight possibility of any modifications.
If a disk becomes part of RAID system, it receives a corresponding label from the RAID controller, whether the one of NAS or of the motherboard, of being in. This label contains information about number of disks in group, RAID configuration, stripe size etc. If a user decides to utilize the disk from a RAID system, this label can still remain there even after the disk is taken out the system and formatted. Despite being used in RAID, the disk may be ejected and successfully used for other purposes – as a basic hard drive in a computer, in another data storage medium, as a removable storage etc.
In case when data recovery is required and the disk is opened in Recovery Explorer, the program scans its properties to define the type of device. In case with the disks that are or used to be part of RAID, R-Explorer would read their labels and suggest assembling the disks into one solid system. At the same time, the program performs this assembly in an automatic mode as a response to the user’s permission.
If you are sure about the disk ready for a recovery scan only used to be part of RAID before and is not part of RAID anymore, refuse the automatic RAID assembly offered in the program message, you can also ignore the warnings before the scan start. Otherwise, if the disk is taken out of RAID, you should make sure that all other disks – the components of this RAID – are also attached, and assemble RAID. You can do it manually or allow the program to perform it automatically.
