Ubuntu – “the partition is misaligned” error in Disk Utility – should I repartition


I have a Dell XPS M1330 laptop that has Vista installed and I just installed Ubuntu 10.4 LTS so I can dual boot.

Everything seems to be working well, but when I opened the Disk Utility to have a look, almost all the partitions on the hard disk are showing the warning WARNING: The partition is misaligned by xxx bytes with xxx being anything from 512 to 2048 to 3072 depending on which partition we are examining.

Example of such a warning (picture by Kendor): Example warning

The warning is suggesting repartitioning, but I am not sure if it would be helpful. So here are my questions: is repartitioning really necessary, what tool should I use to do this, and will repartitioning the Vista partition damage it?
