I recently

restored (using the Acer restore tool) my laptop which has two 250Gb drives, since the restore I have only a C: (see attachment) for some reason I have a disk 0 with just 3.3Gb

that I assume is my former D: and disk 1 is working fine. The system is working fine, both drives are ok in both the BIOS and Device Manager.
I need the storage space of the second drive to recover all my graphic data so appreciate any help.
Thanks
