It's hard to say. If the disk is borderline it's possible for it to be readable in one drive and not another. I have a couple of working machines with 3.5 inch drives so maybe ask around if a coworker or someone else you know has? I've read diskettes older than that but you never know. GreaseWeasel mentioned in the other comment might help as well.
