hai, Thanks for responding to my query, actually it is a raid5 storage device it contains firewire and usb ports, through this interface a user can store data to the raid5 device irrespective of file system. once he copied data to the device it should be immutable(i.e cannot be modify and delete). Can u suggest any approach to achieve this task. bye ppk --- Александр Деревянко <aeder@list.ru> wrote: > prasadam kumar wrote: > > >hai, > > > >I am working Raid5 storage device and i want to > make > >my device WORM(write once and read many) and > >undeleatable.
