On Windows NT operating systems, CHKDSK can also check the disk surface for bad sectors and mark them (in MS-DOS 6.x and Windows 9x, this is a task done by Microsoft ScanDisk). The Windows Server version of CHKDSK is RAID-aware and can fully recover data in bad sectors of a disk in a RAID-1 or RAID-5 array if other disks in the set are intact. [11]
Because Windows has an approximately 70% market share of desktop systems worldwide, that defect spread quickly. In a statement, CrowdStrike said the problem was immediately isolated “and a fix ...
A bad sector in computing is a disk sector on a disk storage unit that is unreadable. Upon taking damage, all information stored on that sector is lost. When a bad sector is found and marked, the operating system like Windows or Linux will skip it in the future. Bad sectors are a threat to information security in the sense of data remanence.
The software can also be used to generate and sometimes repair bad sectors. Recent versions include support for DCO restore and freeze operations, HPA security (password) operations and simulated bad sectors. [2] ATATool is no longer available for personal download and can only be used for "professional users" like for security researchers. [3]

When using sector slipping for bad sectors, disk access time is not largely affected. The drive will skip over a bad sector using the time it would have used to read it. Spare sectors are located on the disk to aid in having sectors to “slip” other sectors down to, allowing for the preservation of sequential ordering of the data.
TestDisk is a free and open-source data recovery utility that helps users recover lost partitions or repair corrupted filesystems. [1] TestDisk can collect detailed information about a corrupted drive, which can then be sent to a technician for further analysis.
On the Windows platform, many programs designed to monitor and report S.M.A.R.T. information will function only under an administrator account. BIOS and Windows (Windows Vista and later) may detect S.M.A.R.T. status of hard disk drives and solid state drives, and give a prompt if the S.M.A.R.T. status is bad. [25]
