Which metric indicates unreadable sectors waiting for remap?

• A. Current_Pending_Sector (ID 197)
• B. Reallocated_Sector_Ct (ID 5)
• C. Offline_Uncorrectable (ID 198)
• D. VALUE

Answer: (A)

Unreadable sectors waiting for remap are tracked by the current pending sector count. This SMART attribute reflects sectors that the drive couldn't read on first attempt and are queued for remapping. If a pending sector is read successfully later, it remains; if it fails, the drive remaps it to a spare area and the reallocation count increases. The reallocated sector count shows how many sectors have already been remapped, not those still waiting. The offline-uncorrectable attribute indicates sectors that cannot be corrected at all, a different failure state. VALUE isn’t a valid SMART metric. So the best indicator for unreadable sectors waiting to be remap is the current pending sector count.
