On the count from 1-10 : I would give your disk 9.

This number means that 4948 sectors died on you, but the disk firmware has managed to relocate/remap them to spare sectors. This number is very large and shows a disk that I wouldn't trust in the long term.

The reason I don't give it 10 is that the evaluation of the disk's firmware of this parameter was 77, while the failure threshold was 36. This means that the disk has more than 10000 spare sectors. In addition, the "Uncorrectable Error Count" is zero, so you had had no sectors with hard failure.

You may continue to use the disk, just ensure you have backups for the important files. Keep an eye on the two parameters of "Reallocated Sector Count" and "Uncorrectable Error Count". If either one starts climbing up, then the disk's state is degrading.

On the count from 1-10 : I would give your disk a badness level of 9 (where 10 is extremely bad and 0 is perfect health).
