That is VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY bad. The 460 does not come with a recovery disk, just a recovery partition, and you just lost yourself that by reformating, that may not be a big deal to you until you realize that sony uses custom software to control the shortcut keys (you cant even use the volume shortcut keys without it), and as far as i know, have not looked to much into there website, but i don't think it is online.
your are going to have to buy new disks (1DVD + 1CD) unless the software is somewhere on there website,goodluck and sorry.
