WD Book Studio Ed won't turn on

I may have erased the driver…  How can I download a driver for model 3809A?   Thankk you.

I have checked the power supply out put for voltage…  Appears good…  I have listened for the spinning…  I can hear a noise if I put my ear right up to it…   I have tried another wall plug…    I have swapped out some cables,  USB for Firewire.  No effect…   I have restarted a few times…   All to no avail… 

I have it working…   I followed the FAQ :  “No Longer Shows…”   and worked through the suggestions.    #7, Try another computer…  I hooked it up to my wife’s computer (brave eh?) .   It seemed to download a driver(s) and I was able to access data opn the drive…  When I came back to my computer I don’t exactly remember how but there too it started and I could access data…  Thanks FAQs…
