Samuel, please,

What's the difference between run this two commands?:

dd if=/dev/zero of=debian-hurd-03102010-qemu.img.tar seek=2146959359 bs=1 
count=1

dd if=/dev/zero of=debian-hurd-03102010-qemu.img seek=2146959359 bs=1 count=1

Do both "the same thing", or not?.

Thanks, in advance.

Best Regards.

Jose.
