The types of bad sectors include logical bad sectors, physical bad sectors, and the more common read/write delays. If there are sectors to be remapped in S.M.A.R.T., you should pay attention to the health of the hard drive. When we find that we cannot enter the system, and the hard disk cannot be recognized when booting or under PE, we should use a hard disk detection tool to make a scan to see whether this problem is caused by bad sectors. Logical bad sectors on a hard disk can generally be repaired using DiskGenius, but if they are physical bad sectors, then for ordinary users, your only hope is HDD Regenerator, before you send it to a professional for repairs.
