About this tag
Hard drive health on WindowsForum.com centers on reading SMART data rather than guessing from a drive's age. The tagged discussion walks through Reallocated Sectors Count (attribute 05) and the related C5 and C6 values in CrystalDiskInfo, explaining that spare sectors are swapped in when areas can no longer store data reliably.
