just wondering how I can unpartition a hard drive under debian.

i recently partitioned it using 

cfdisk /dev/sdb

and would like to revert what I did.

Thanks

If revert means 'undo all my changes, and automatically put things back the way they were before', that's not going to happen. – Mike Renfro Jul 18 '11 at 11:36

Run 

cfdisk /dev/sdb

then use command "d" for the each partition.

    man cfdisk
    COMMANDS
    d      Delete the current partition.  This will convert the current partition into    free space and merge it with any free space immediately surrounding the current partition. A     partition already marked as free space or marked as unusable cannot be deleted.
