Other than some special vendor utility or BIOS utility, low-level format doesn't make sense for IDE disks. There is no command for "format" and trying to reset the geometry like the old days doesn't even apply to modern disks. If you want to try a low-level format tool (for IDE that is probably just writing 0's or 1's to every sector on the disk and letting the hard disk automatically map bad blocks), I would just dd all zero's to it then try to create a filesystem. If you still get media errors, your disk is foobar or about to be foobar, its cheap and you already stated you don't have any critical data on it so buy a new disk! :D In fact Seagate offers a Windows too to do exactly this called ZeroFill: http://www.seagate.com/ww/v/index.jsp?vgnextoid=65a8783c970ce010VgnVCM100000dd04090aRCRD&locale=en-GB Not trying to be too cheeky here, but I think what you are asking doesn't makes sense...at least to me.... Thanks! -aps
