opening up disk management, I'm am able to right click on my main partition (c), and have the options of shrinking/extending volume, properties, change letters/path. when I right click on partition (d) the only option that arises is "help". I've also gone to the command line> diskpart>select disk 0> list volume>select volume> extend. this didn t work for recovery (d), but worked fine for (c). this happened all the while I had 48 Gb of unnalocated space.
