You sound as if hard drive corruption if communicable like a virus, etc. It is not.
To get a better understanding "corruption", you might look at:
Causes of Data Corruption - http://ezinearticles.com/?Causes-of-Data-C...n&id=817785
File Corruption & Its Consequences - http://www.smartcomputing.com/editorial/ar...3.asp&guid=
Hard drive problem situations are varied (bad sectors, file corruption, file system corruption). File corruption and bad sectors are very common, while file system corruption occurs less frequently.
So my question is: Exactly which of the three examples above...do you really think applies to your case? Did you get an error message? If so, please post it exactly as it appeared onscreen.
