Well, it's simple with his tool. I more meant to stress that it is
possible
to change sector size of the drive, despite what you've been told.

[here you need to format].

He said that he successfully used 4K sector size for testings.
But, as it was stated in this thread too, Linux does not support
any sector size different from 512 bytes yet.
With my 73 Gig drives I was thinking to have a look around
how much hacking is necessary to get a simplest fs going -
if you'll find something please kindly inform me, I'm interested too.
