[parted-devel] resizing FAT partitions does not work at all

[Curtis Gedak]

Hi Jim,

The script t3000-resize-fat.sh generates the same results for when I use 
parted-1.9.0.

After some testing, it appears that parted does not like to resize FAT32 
file systems if they are smaller than 256MB.

By making the below posted changes to the script I was able to create a 
FAT32 file system of about 256 MB in size (aligned to a cylinder), and 
then successfully grow it by about 8MB (one cylinder).

Hope this helps :-)
