Sandisk cruzer 16gb only shows up in devices and printers on my windows 7 tosh laptop?

Hi , as message suggests i got the above flashdrive and it will not show up as a mass storage device on my laptop, it only shows up in devices and printers. All drivers installed etc. It works on my vista desk top and my work desktop with windows 7, no problem!

So far I tried to fix it through disk management but get a message saying my disk mgmt consol is out of date when I tried to rename it as a drive. I refreshed  and rebooted as they said but still no joy?

Any help would be appreciated,
