This sounds a little addled ... please give a layout plan of your drive
Code:
fdisk -l /dev/sdx #where x is substituted with your actual drive-letter
.
Generally speaking: You also have to adjust your /etc/fstab to the new layout and also file system type i.e. the mount options in /etc/fstab have to fit. If you already did that, please post your /etc/fstab as well.
