Windows Upgrading Question

[Taera]

I know an upgrade will wipe my HD clean but I was wondering, will it also wipe my storage HD clean too? I'd hate to lose a TB worth of stuff. Thanks.

Just unplug it while doing to install to avoid the risk, but no it won't force a wipe of another drive. It doesn't force a wipe of the OS drive either, it just moves stuff to windows.old as the folder for programs and the old OS.
