you'll be ok.  The worst that'll happen is you'll need to
 find a fancy SCSI utility to reformat your drive while giving you
 a lot of control over *how* it's reformatted. 
 Any suggestions of a name I should be seeking? I presume this means
 that there is not something already open-source or built-into Linux
 (a device driver that could be altered)? This latter aspect might
 need to be explored since if I want to 'dd' the contents for a
 backup then I would need to construct a way to save the extra bytes. 
 
Check out sg_dd, a part of the sg3_utils package.
