Well, just a quick update - I rejumped it ( trying all the settings ), and I then noted that the drive wasn't spinning up. I removed the top cover (invalidating the warranty! lol ) and noticed that the drive didn't spin up at all. I naturally turned it off, spun the platters around (by the axle, taking care not to touch the platter surface). I powered it back on, and it spun up!
You've experienced, and temporarily overcome, "stiction" (stickiness + friction). There are several causes, but the most common turns out to be a bad disk coating in some production runs of certain manufacturers. There's a nanoscopically thin protective coating on some of these, and unfortunately it can turn to a tacky glue. Old Quantum drives from about the 40MB generation to the 100MB generation or so were particularly prone to this, and so were the 20MB Sony drives that shipped with many SEs. I've opened up lots of those to do post-mortems, and the head is actually stuck to the drive surface on many of them. If you ever get them to spin up, don't power them back down. Back up your data as soon as possible, because that drive is not long for this world.
Other sources include balky bearings (including bearing lube that turns gummy after some years of use). Since the head isn't involved there, there's less risk of disk surface damage, but you should still replace the drive sooner than later.
