have you done an antivirus scan yet? My suggestion is to sort through each attempt and of course the above suggestions. If you have critical data and you can stand the down time I would log those 32 attempts and take it off the network.

That way if the hack is monitored by the hacker and he knows that he's been caught then he might fire your drive. But most of the time these are just spammers making money off your bandwidth...

Good luck to you...
