Title:
  creates a misaligned partition

Status in “gnome-disk-utility” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: gnome-disk-utility

  I installed a new 750GB disk in the expansion bay of my X201, and then used 
Maverick's disk-utility to create a GUID Partition Table.  
  I then made a new 250GB partition at the start of the disk.  Next time I 
opened disk-utility, I saw a warning: "the partition is misaligned by 3072 
bytes.  This may result in very poor performance.  Repartitioning is suggested."

  I then deleted the partition, created a new one, and found the exact
  same problem occurs.

  1- If disk-utility is smart enough to know this partition layout will cause 
poor performance, it shouldn't create it!
  2- Does this actually cause poor performance on modern hardware/kernels?
