Problem with my HDD and FS's after upgrade and cloning the HDD

[James Brown <jbrownfirst@gmail.com>]

Hi all,
I use the Debian Lenny AMD64 on my laptop Acer TravelMate 3043.
After upgrading from my old HDD 120GB to 500GB and cloning the first to
the last, I have the next problem:
sudo fdisk -l

Disk /dev/sda: 500 GB, 500105249280 bytes

Some people tell me that the "Partition x does not end on cylinder
boundary" is not serious problem and advise me to do not call attention
to that.
But some other people tell my FS's can crash through that and reccomend
me to reinstall my system at all.
What can you advice me with that?
