Hi Guyz,

I need to format a hard drive the quickest way possible, without the user knowing what is happening?

For those people who may think tis is dodgy stuff, read on.

I am writing a little program that starts then hides itself when windows starts.
It then wait's say 10 minutes then calls the number that  my computer is plugged into, if the number is engaged then fine, but if the computer has been stolen and plugged into another phone line  it will ring my number, and when it does I want to Format my hard drive remotely.

That's it..

200 point for the smothest answer..
Andy

see Win32 Developer's Reference about DeviceloControl
IOCTL_DISK_SET_DRIVE_LAYOUT     Partitions a disk.
IOCTL_DISK_SET_PARTITION_INFO     Sets the disk partition type.
IOCTL_DISK_VERIFY     Performs logical format of a disk extent.
