Within 2 weeks, your drive's read error rate has worsened (I don't know enough to quantify how bad) and its "unstable" sectors count has gone up from 105 to 218. Definitely a bad sign. Especially if it wasn't due to something like a physical bump while the drive was trying to read/write, it's more like it's going out on its own. And if it is really going out on its own I'd be worried about rapid degradation.
As previously mentioned by other posters you should run the manufacturer's diagnostics program on the drive, and if the results dictate, use the warranty.
Backup first, get software inventory, license keys, etc. (before running diagnostics).
You should always have that stuff anyway...
