Yes, with emphasis on "something like" ;) /dev/null would return an
immediate EOF:

0+0 records in
0+0 records out
0 bytes (0 B) copied, 1.1466e-05 seconds, 0.0 kB/s

If you really must do this, use 'if=/dev/zero' instead.

But, as others have implied, you don't need to zero out the disk, you
just need to either change the partition boundaries or just reformat.

Using the partitioner's "expert" mode, you would select the partition
you want to overwrite and tell the installer to reformat it.

Cheers,

Just a habit I've acquired over the years - I like to have the hdd blanked
with zeros to ensure there are no ghost/residual files left on any of the
sectors before installing anything.

That's *completely* and *utterly* nonsensical. mkfs wipes over the
existing file structures.

I was just looking at the stats for this thread: 38 total replies (not
counting the spinoff/individual replies), of which three were directly
helpful responses (thank you Aioanei, Theirry and Bob) which led me to more
specific Googling, which led to my ultimate solution.

Have we lost our way a bit on this list?

There *is* an OT list, now.
