Please post EXACTLY what you typed (preferably using the [code] tag so we can see everything), EXACTLY what you're trying to accomplish, and EXACTLY what error message you received.

busybox gzip -dc /data/local/sr0/*.gz | dd of=/dev/block/sda16 seek=8984375 bs=512 > /sdcard/IAB\ WORK/diskb.dd.rtn

it returns dd: ftruncate: Invalid argument

seek=8984375

Are you sure it's valid?

And why is there a backslash?
