Back in August I had to reinstall Windows 10. I made an uneducated decision to shrink my 128 GB SSD to 28GB and move the unallocated 100GB to my HDD. I thought I did anyway. the more I think about it now, I don't even think that's possible. Bottom line is I'm constantly getting messages that there's not enough space on the drive & that unallocated 100GB is nowhere to be found. Can this be reversed at this point or did I just screw the pooch on this one? for the record, the HDD is 500GB & it looks like it's all there, but not the missing 100GB that I thought I could magically move from SSD to HDD.
