Help needed disk formatting in embedded system

tanalam

hi all,
I have to format a disk which is used in an embedded application with an rtos.
I can do it using PC (through USB). But is it possible to have a code incorporated in the file system iteself so that the system(embedded) can do formatting of its hard disk without too much assistance from PC, and take care of marking/segrigating the bad sector....
Plz reply ..its urgent
TIA

Tan...
