Fred's advice is good here - many of these drives are likely to be very important to archivists and preservationists (there are several of us on this list) and not general-purpose "PC" devices. Chuck was an expert in many things relating to magnetic storage, and a rare expert indeed in tape recovery. (I'm not one of those. I sent all my tape inquiries Chuck's way.) I can't imagine how I'd go about this, but we all should probably start thinking about succession planning if we haven't yet. :-) Perhaps recruit people in his contacts list to see if anyone is able to swing by and help sort into categories and subcategories of interest? The entirety of this collection would be "a lot" for any one person (or institution) to deal with, but being able to mete out portions to various experts might help make it more manageable.
Chuck meant a lot to us here. We miss him deeply. My condolences to you and your family.
