Bingo, thank you.
Disk /dev/sdb: 1500.3 GB, 1500301910016 bytes
255 heads, 63 sectors/track, 182401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000dd427

/dev/sdb5 31 182401 1464895026 8e Linux LVM
Now how do I re-align my drive? The first partition is /boot, so I
don't really need to do that one. Are there GUI tools I can use,
preferably on a live CD?
