A single question (about how to recover data from the obsolete drive). Although, it's possible that a museum or archaeology team could post a question asking to identify a relic.
Just because there's only one question (currently!) for a tag, does not mean that the tag is useless or unwarranted.
- It's specific (a type of hardware)
- It's unambiguous (not going to be confused with other types of drives or software)
- It adequately categorises it's question.
- If another zip-drive question is asked, the tag will exist for the new asker to use.
Single-use tags aren't always bad. A topic may be small enough that only one or two questions are asked, and that's ok! It's the ambiguous meta-tags we need to watch out for.
I think this tag is fine. Indeed, searching for 'zip drive is:question' yielded some other results that should utilise the same tag
(I can't remember where but someone made the argument for single-use tags better than I can, if I find it I'll link it)
