What is Offline_Uncorrectable (ID 198)?

Explanation:
Offline_Uncorrectable reflects the number of sectors that could not be read and could not be corrected even when the drive performed offline data collection. During offline data collection, the drive checks for bad sectors; if it cannot recover the data with its error correction, those sectors are recorded as offline-uncorrectable. This means the data in those sectors is unrecoverable and they are not eligible for remapping. That’s different from sectors waiting to be remapped (pending) or sectors that have already been remapped (reallocated), and it’s not a simple health score.
