Help Please..

Hi All,
I am getting an error "File names.dat may be corrupt". So I download 
Analyze.exe from Microsoft website and run it in it showed alalyze 
successful. When i saw in vss the file name is blank if i try to deleted it's 
giving me the same error names.dat may be corrupt can any one help me please. 
However, based on the Analyze report, I got some message like "the file 
'E:\test\data\a\aabeaaaa' unable to read the format or header, appears to be 
corrupt", and the file (test.vbp) still can not be deleted from VSS 
successfully.
 Therefore, would you mind telling me how could I fix this problem?
