The drive was in my windows computer so it's NTFS formatted. At first Windows would only list some of the files in it. So I rebooted -- then Windows did not recognize it at all and the disk utility in Windows said I needed to initialize the drive. At that point I realized it's probably failing so I shut my computer down and disconnected the drive just in case. So now that I have a NTFS drive whose only symptom is "doesn't seem to work anymore", what are my steps to try to recover the files? Some of them are backed up to the cloud so that's no problem, but the most important one whose backup has been silently failing (great job, Backblaze 🙄) is a large encrypted Veracrypt volume with personal data on it. Like I said this data isn't absolutely critical, anything important to me I can probably get from another source, but it would be convenient to recover it and move it to a working hard drive.
