I have a hard drive that I want to overwrite, not with null bytes, but with a message.
48 69 64 64 65 6e 20 = "Hidden "
Here's my command thus far:
echo "Hidden " > /myfile
dd if=/myfile of=/dev/sdb bs=1M
Note: I have also tried an assorment of parameters such as count and conv to no avail
Now, this is fine. When I run:
dd if=/dev/sdb | hexdump -C | less
I can see the first few bytes written over, however, the rest is unchanged. I'd like to recursively write "Hidden " to the drive.
