Problem with new Samsung HM121hc disc

[DB]

Hi All,

Sorry to bother you all again....

I just bought a 120GB Samsung HM121HC disc, and cannot get it to 
'work'.  I tried puting it in an external box , plug it in, can feel 
motor is spinning.  But nothing comes up.  Qparted & Gparted do not see 
an external device.  the KDE Info says a Mass Storage Device is atached 
to a usb port.  lsusb shows me the name of the maker of the housing.....

Anyone any ideas how to check that what I have is compatible with my 
system before I ship it back? (purcahsed in the UK whilst visiting, now 
back in Austria.....)

As ever, all suggestions greatfully received!
