Long story short: I got a 512GB SSD to replace my 256. Decided to clone my drive using Macrium Reflect but it also cloned the partition size, so now about half the drive's space is being wasted (gray area far right on the screenshot).
How do I fix this? Is extending the volume the only way?
Any and all help appreciated.
P.S. I would much rather take back the disk to factory defaults (no partition) and redo the cloning if that is somehow possible. Right now I'm stuck with a 211GB partition on E:, which is exactly what I do not want. I want E: to be a ~500GB partition. Please help.
