By much beloved PDP 11/23+ running RSX 11/M+ has a 20 Meg Seagate that after
20 years is giving me a few read errors.

Is there a way for me to save this drive (i.e.: sub-level format)?

It's very disturbing to me to watch an old friend suffer so.

Thanks for your time and consideration.

(I'm going to cross-post this to other DEC related newsgroups I hope no one
minds)
