I took out my one hard drive and put it in an encloser to use it like an external hd. Also i wanted to use it for like pc repair back ups on other pc's. IS it possible to have an antivirus protect it, if i hook it up to a non-protected pc. For Example, Like a non-protected laptop infected with viruses, so i can put someones backup stuff on my hard drive, without infecting my external with viruses. Is this possible? I don't think it is.
