Cloned my Windows SSD to a larger drive, but the extra space is missing.

I cloned my 500GB Windows SSD to a 2TB SSD, and Windows boots normally from the new drive. But the main partition is still around 500GB, so the remaining space shows as unallocated. Do I need to resize the partition after cloning, or did I miss something during the cloning process?

mike_t_ If Disk Management is showing the rest as Unallocated, then the clone itself probably worked fine. You basically copied the old 500GB partition layout onto the 2TB drive.

Right-click the Windows partition and see if Extend Volume is available. If it is, you can extend it into the unallocated space. No need to clone again.

fixeditonce Yep. A clone doesn't automatically mean "make the partitions bigger."

Think of it as copying the partition map along with the data. If the source had a 500GB C: partition, the target can end up with a 500GB C: partition + ~1.5TB unallocated.

The important part is where that unallocated space sits relative to C:.
