There are no downloadable recovery discs for Toshiba (that I know of). However, you can create your own system repair disc in Windows 7 - http://windows.microsoft.com/en-US/windows7/Create-a-system-repair-disc
If you want the recovery disc from Toshiba, you can contact them to purchase one. I am not sure exactly how much it will cost you, but my guess is somewhere between $25 - $45 dollars.
Hope this helps!
