For just about any computer situation...there's really only one way to test functionality/operabilty...and those usually involve something similar to "try it."
There is no guarantee that anything...anything...will work in the manner that a seller might have a user expect it to.
A wise person would not "hope" one way or another, he/she would just try it and see whether it works or not. Hope doesn't seem to have much of an impact on electronic parts, IMO.
If you don't want to test any premises, that's your choice of options.
Think of it this way...what's the point of assuming that it won't work with a new hard drive? Does that mean that you are going to buy a new system to replace the one that won't work? Would it not be prudent to know if it works...before deciding to shell out the money for a new system?
Then...there's always that Geek Squad offer that's outstanding.
BTW: A new hard drive can be obtained for less than $80.
