You need to start from the Recovery HD and run Repair Disk on your internal HD. See #6 in Using Disk Utility, especially the yellow box.

You're trying to make a Lion Install disc or partition? If so, see Making a Lion Install disc or partition.
If you want a Snow Leopard Install disc, you have to purchase one. Apple has them for $29. You can copy that to an external HD, etc., but not via drag and drop -- you have to use the Restore tab of Disk Utility, or the 3rd-party CarbonCopyCloner or SuperDuper apps.

Sorry, but I'm confused.
Are you trying to Install Snow Leopard on the new partition of your internal HD? If so, do that directly from the Snow Leopard Install disc. See the REINSTALLING OSX section of the pink box in Installing the ''combo'' update and/or Reinstalling OSX.
If you're trying to copy the Snow Leoaprd Install disc, just copy it to the USB stick, with the Restore tab of Disk Utility.

. . .
i cant directly install snow leadpard on my hardrive as it wont let me as im running lion
Sure you can, as long as it's formatted Mac OS Extended (Journaled).
You have to select the new partition as the destination, not the Lion partition.
