is it measured by percent or GB?
for me, i get a SSD with 120gb but i divide them into 2 parts ( 40 GB and 60GB) and the rest is hidden( i don't know how to recover it but it is ok now, so i don't try to save it)
and i for the OS partition (40GB), it is occupied with 15GB only and i save other data on 60GB partition(only 1gb occupied as it is a new netbook) |
