It may really only be the cable in your case, but I'd be careful nevertheless. When a hard drive of mine did the same thing once, it seemed to work fine afterwards, too. Out of paranoia, I ran the SMART tool, and it showed some info about failed spin-ups (not surprising), but apart from that, "everything is good, nearest expected TEC in November 2026", so I said "fine then...", backed up the most important stuff just to be sure, and went back to work.
The drive worked nicely until I turned it off the evening, and the next day, it wouldn't even try to spin up or something. Of course that may be entirely unrelated, you'll never know. But it's something that will definitively make me back up all data and replace the drive on the next possible occasion, if any drive ever does something similar again. It also teaches you how utterly useless SMART is.
