Assumed: I have seleicted
sd7 at random as a device number. Please watch your kernel messages when inserting the device to discover the actual drive number, and replace accordingly.
Code:
# dd if=/path/to/the/file of=/dev/rsd7c
Q: What the heck is rsd7c?
A:
r = raw device
sd7: drive number
c = the reserved partition letter that means "the entire drive, starting with LBA (sector) number 0"
You may add a blocksize to the dd(1) command, such as
bs=1m.
