I need to resize the NTFS partitions of my disk from Linux.
I've found two ways to do it :
the first tool works under the shell,it is good,but I read that it is not secure because it does not resize really the partitions,it modifies only the partition table. I don't like too much this way. The second one is to use gparted. Here the problem is that I should make the unattended partitioning of the disk for third party,assuming that they aren't so experienced to do it by themselfes.
For unattended partitioning I mean that I have two choices to do it for someone :
1) use some kind of tool able to record the keys pressed and the mouse buttons clicked
2) use gparted without gui
3) find a tool that does not alters only the partition table,but that makes a real resize of the NTFS partitions,that works without a GUI.
Please suggest something to me. 10x
