Well, it took half an hour to install libparted and write some code. No 
documentation about this lib: ldap was well documented instead.

I attach a sample project which calls just three libparted functions; I 
had to consult the include files.
It is not so simple, but hey! You want to fiddle with not-so-easy things...

The big problem is with strings - I don't know why gambas strings don't 
map exactly to char* in C, but there must be good reasons (well I readed 
something about, but can remember well). You can pass gambas string 
straightforward to C char*, but you can't do the inverse.

Anyway, in the attached project you can see two or three useful things: 
how to declare external calls, how to read C strings, and how to cope 
with pointers to structures. I suspect the structure must be freed, but 
I didn't have the lust to read all the .h about parted... :-)

The project simply tries to open /dev/hda, hdb, hdc and hdd. Perhaps you 
have these newer SATA disks... if so, you have to change the source.

Have fun; if I can help I will try - but I don't want to read all that 
libparted documentation (well, *no* docs, only C include files...)
