BUG on parted.

[Eduardo N. Hering]

Hi list!

I tried parted to increase the size of the ext2 partition on the
SD card, created by RamdiskRescue. I seems that there is a
bug in parted.. Any ideas on how to fix it?

Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) help move
  move NUMBER START END                    move partition NUMBER

        NUMBER is the partition number used by Linux.  On MS-DOS disk 
labels, the primary partitions number from 1 to 4, logical
        partitions from 5 onwards.
        START and END are disk locations, such as 4GB or 10%.  
Negative values count from the end of the disk.  For example, -1s
        specifies exactly the last sector.
