My laptop has two drives a C(14GB) drive and a D(283GB) drive. The OS is in C drive. Since yesterday the D drive has gone missing. When I go to disk management it shows 283GB space,but no letter is assigned to it. When I try to assign, it says diskmanagement console is out of date. So, I used EASEUS partition recovery. All the files are intact but I have no sufficient space to move the data into as the data shows 160 odd GB and my laptop now has only 14GB. However the 283 GB is unaccounted for. How can I copy all those files into the 283GB partition. Please help. Thank you.
