hi, tried diskmgmt.msc but it's not showing, only shows my C drive (disc 0) and cd-rom. i take it this is not good news? :(

hi, ive got a problem with my samsung s2 1tb which suddenly stopped working. Tried unplugging etc, reinstalling drivers but nothing works. it shows up on my hardware devices with no problems but cant access it to reformat which would normally be my 1st port of call as i've resigned myself to losing any files i've got on there. any help would be greatly appreciated. have also tried chkdsk with command prompt but gives the message "cannot open volume for direct access". thanks in advance
