this has worked, when I used the command it echoes:

Disk /dev/sdc doesn't contain a valid partition table



thus /dev/sda is the system drive, and /dev/sdc is the 1tb drive I mentioned.

I'll try to zero the drive later as this is quite time consuming,

Linux zeroing is the only practical way to wipe a drive, as you cannot
wipe data on Windows,

on Windows even if you delete files, empty the recycle bin, delete partitions,
create new partitions with different boundaries, fully reformat these,
most of the files and directories will all be there if you use a good
salvage program such as File Scavenger 4.0!

there is a video on YouTube which shows someone doing a full reformat
of a volume and retrieving all the original files with the above program,
I tried this out myself and the video is correct, I successfully viewed photos
on
the drive salvaged by the program.


I bought some file wiping Windows software which also wipes drives,
but it wipes the sectors using the same strange multipass algorithm
used for files, I wanted to do 32 passes, but even after 8 hours
it hadnt even completed 1 percent!

on trying this what I found is that tab completion of /dev/ and /dev/sd show
the drives
but only if you do this in context eg:

dd if=/dev/[tab]

and

dd if=/dev/sd[tab]

show all the drives, but if you try:

$ /dev/[tab]

or

$ /dev/sd[tab]

it doesnt show the drives


I am used to a computer system where tab completion shows everything
regardless
of context,


anyway, you have successfully answered every question I asked on this topic 
in various emails!
