where can i get a orignal  set  of  disks  etc  that  came with  my device  ,  

if  ever i need  do  a  complete reinstall im  currently  stuck.

so  do  any  one no  what i need to get.   eg  cd , usb ,  manuals  drivers disk etc

this  is   for  if   my   device   has to  be   formatted  or  upgraded etc

thanks
