Hi,
It is not Haskell specific. You just have to read from the partition
device special file (e.g., something like /dev/sdb2) as you would do
with a normal file. You must have the permission to do so (e.g., be
root). Be careful as you can destroy your system if you write something
incorrect in your partitions.
Repositioning handles:
