I have an external 100 GB usb hard drive, partitioned into 2 eqaul sizes. I recently moved some files from one partition to another disk. the files got moved, but the partition is not showing the freed up space? where has it gone and how can it be reclaimed?
If you Moved the files to another disk, what probably happened is that they were "Deleted" from the original location. But Delete does not really do that. It simply alters the records to re-locate them to the Recycle Bin in case you change your mind later and want them back. So try emptying the Recycle Bin ON THAT DRIVE and see if you get all your space back as expected.
