Every time I was running this it would 'complete' but still show the drive as 'not aligned'. So I tried to run checkdisk then rerun the alignment tool... well that completely hosed my drive and now I can no longer boot from it. I had to reboot with my 'old' drive since it wasn't showing up as a valid boot disk. In Disk Management it now shows as "unallocated space". This is unbelievable. I bought this tool so it would save me the time of doing an fresh Windows install on the SSD... this is after buying Arconis True Image which was supposed to do the drive alignment. So after 2 hours of trying to get this to work I am now stuck with a destroyed Win7 install... I submitted a support request... but nothing back yet. if anyone can offer some advice I am all ears. I really wanted to keep my current install intact.
