sda / sdb after boot

I want to automatic mount a ntfs partition after start. I work on fstab, everything seems to be ok, but now something strange is happening: sometimes after boot, when I use fdisk, I find all the partitions as sda, sometims they seems to appear as sdb. Of course, if in fstab I have written sda and they are sdb, they will not be aoutomount...
I am using fedora 14
Any idea why is happening this ? I was expecting that allways the partitions to be sda or sdb.

This is because with sata,usb etc the disks doesn't have an exact physical position as with old ata.
What you should do is use either UUID or LABEL instead of /dev/sd*
Find your uuid and label:
# ls /dev/disk/by-label
# ls /dev/disk/by-uuid

In /etc/fstab, example:
UUID=4706-0137 /media/sda1 vfat defaults,umask=007,gid=46 0 0
