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.

Hi,

I'd like to be able to read and write from/to partitions directly. I've had trouble with the documentation (honestly i can't find anything, and any mention of partitions leads to mathematical partitioning of lists or whatever).

I obviously would need to be able to write or read from a specific position in the partition. Mind you that would be good too for files (that is, being able to read/write from a specific position in it) since i plan on making disk images.

Thanks in advance!
