I have no idea what a "library" is.
Are you referring to an iOmega? I never heard of an Omega.
Why do you have two of them? That is, in fact, asking for trouble.
"Library" is only used in the context of such terms as DLL (dynamically linked library). It plays no role in the Windows environment. Please use standard terminology, as it facilitates meaningful answers.
Actually, I've never heard of MicroSoft, but I have heard of Microsoft.
