dd won't write more data than is provided by the source file, so if your
file is 100k in size then it will write 100k to the disk.
Check out the skip option for dd. You need to loop dd so that write one copy
of the image after another. Here's some pseudo code:
for (i = 0; i < SIZE_OF_DISK/SIZE_OF_FILE; i++) {
dd if=lemonparty.jpg of=\\.\f: skip=i bs=SIZE_OF_IMAGE_FILE
}
Beware of leaving data in slack space!
