Data corrupted after installing Windows Server 2003

Dear all

I had faced a problem that due to corrupt of my Operating System (Win 2003 Server) on c: drive, I reinstall the OS on C: Drive (in Installation I had select Format and New Installation). After completion of installation, On my all other drives (d:,e:,f:,g: ) all data get corrupted. I can watch all folders and folders within folders in all mentioned drives (other then C: ) but no data is existed. Is there any internal option in win 2003, which hides all files. How can I recover it? Please help me.

Are you sure your hard disk is working fine... maybe the hard disk is faulty
