 +=== Interpreting the Results === 
 +
 +''**Reallocated_Sector_Count**'': This attribute shows the number of bad sectors that the drive has remapped to its reserve pool. A rising count is a serious warning sign of a failing drive. 
 +
 +''**Current_Pending_Sector_Count**'': A non-zero value here indicates sectors that are unstable and couldn't be read properly, potentially leading to data loss or drive failure. A rising count is a strong indicator that the drive is close to failing.
