I have just aligned (mostly) two drives on my computer with PAT 3.0. One being a 1Gb HDD the other a SSD. The SSD is my boot drive with 4 partitions C,D,E and F. The 1Gb drive aligned no problem. However the SSD was aligned in partitions C,D and E but not F. I have just tried to align F again and just does not want to do it. Goes through all the boot stuff but no alignment. Is there any reason why the last partition won't align. There are no error messages .
