95/98: No chance since no raw device support.
Figure out which drive number the drive has (NT Disk Manager).
Let's presume it's 2:
$ mount -f -b //./physicaldrive2 /dev/xyz
$ dd if=/dev/zero of=/dev/xyz
Note that "xyz" is a placeholder. Name the drive as you want,
for example "/dev/hdb" or "/dev/garfield"
If you want to access a single partition as raw device, you only
have to know the drive letter, let's presume G:
$ mount -f -b //./G: /dev/earthquake
Note the "//./" prefix (slash slash dot slash) which is the common
prefix for devices in NT/W2K except for old DOS device names ("COMx",
"CON", "AUX", "PRN").
Hope, that helps,
