I am trying to create a raid 1 volume from an existing disk but the keep data option is greyed out.
I am using version 188.8.131.526 of the RST console.
Have 2 3TB SATA disks on a Dell Precision T3500 with Windows 7.
The primary disk is an MBR disk with a an 71MB OEM partition, a 750 MB recovery one and 504GB system partiaion (C drive).
The rest of the space is unallocated but as it is an MBR disk it appears in two chunks - the portion bellow 2TB and the portion above (746GB).
Is it to do with the fact the disk are larger than 2TB?. I would like to convert the primary disk to a GPT disk but not sure if it possible to do this with a system disk without loosing data. The way I got to this configuraton was to create a raid 1 volume from an existing 1TB disk onto a new 3TB disk, then break the raid array back into seperate disks and replace the 1TB disk with a 3TB one, so I was able to create a raid 1 volume without loosing data previously. Now I just trying to reestablish the raid 1 array with equally sized disks.
This system may not meet the requirements to be able to work with 3TB drives, which implies having an updated option ROM with at least Intel(R) Rapid Storage Technology version 10.6. Please confirm in the Option ROM of your system when this is booting, by pressing Control I during the system start up. You may also need to try with a 2 TB drive to test.
