The raw value of this attribute shows the total number of attempts to transfer data from reallocated sectors to a spare area. parameter indicates a count of remap operations (transferring data from a bad sector to a special reserved disk area – spare area). What is Reallocation event count?ĭescription.
When the hard drive finds a read/write/verification error, it marks that sector as “reallocated” and transfers data to a special reserved area (spare area). What is Reallocated_sector_ct?Īnd definition: Count of reallocated sectors. A Partition is simply an area of physical space on the drive platter surface that MUST be one contiguous block, and it is used as one logical “drive”. It is nearly impossible to arrange to have all the bad sectors in one Partition you never use. You cannot move bad sectors around on a disk. This part of the hard drive operation prevents corruption and data loss. The data is then moved to the spare sectors of the disk. The sectors are reallocated when the hard drive gets errors while writing, reading, or verifying data. The only acceptable number of bad sectors for the OS to find is zero. We recommend you immediately backup your drive and replace it with a new one. A continually increasing count is serious and generally an indication of an imminent hard drive failure. How many reallocated sector count is bad?Ī reallocated sector count above zero is not necessarily bad – what’s more important is how that count grows. The only way to remove a reallocated sector is to purchase a new hard drive. Once a sector has been reallocated, the hard drive will no longer use it and tore data on it. There is no way to fix or lower your reallocated sector count.
How do you fix a reallocated sector count? Essentially, the reallocated sector-also known as bad sector or bad block-is an area on the disk that is no longer safe to store data.
