SOS-Samsung hxmu0320a/d42 portable hard disk failure

[MsWaiting]

My brother's portable hard disk (Samsung hxmu0320a/d42) is failed to open when click it. It says "the driver is corrupted and not accessible".
There are heaps very important information and assignments which he needs for uni, and two years hard working in there. He is devastated.
Would someone out there could help??? or give some helpful tips to recover data, crying for help...please!!!!
Millions thanks.
