Running "hdparm --read-sector 3299402936 /dev/sda" according to https://www.smartmontools.org/wiki/BadBlockHowto shows that the formerly bad sector is readable, so I'm not sure why the "Uncorrectable Sector Count" is still 1. I don't want to force it to be marked as a bad sector unless I'm sure it actually is bad - if the error happens again with the same sector, I can always mark it as bad later.
Before I retired I worked in remote sensing which involves lots of data moving through lots of drives. Over the
years we had many drives fail, and learned that it was best to replace a drive at the first sign of problems. We
also found that failure rates increase rapidly after the warrantee expires, so started replacing drives at the end of their warrantee period.
Unless you have a lot more time than money you should consider replacing the drive. If it is under warranty you should try to run the vendor's diagnostics to get a return authorization (some vendors accept a smartmontools test report). We had some non-critical uses for old drives (e.g., transfering a system image between boxes) where recovering from a disk failure was a small chance of lossing a few hours against the certianty of spending a few hours to arrange the purchase of a new drive.
