CHKDSK found one bad cluster and added it to the $BadClus NTFS metafile. This means that Windows will avoid it from now on.
CrystalDiskInfo is showing 1 Pending/Uncorrectable sector. This sector will now remain in the "pending reallocation" state until the next format (because it is now shielded from writing by the OS by $BadClus).
I would keep an eye on SMART, and refrain from entrusting this drive with your important data. Note that the raw values of the Read/Write Error Rates are non-zero, so the drive is starting to become unreliable.
Anyway, 62456 hours is a good run.
