The sector won't respond to read or write requests. bad disk Bad sectors can occur on both traditional magnetic hard drives and modern solid-state drives. There are two types of bad sectors -- one resulting from physical damage that can't be repaired, and one resulting from software errors that can be fixed. Types of Bad Sectors There are two types of bad sectors -- often divided into "physical" and "logical" bad sectors or "hard" and "soft" bad sectors. A physical -- bad disk error or hard -- bad sector is a cluster of storage on the hard drive that's physically damaged. The hard drive's head may have touched that part of the hard drive and damaged it, some dust may have settled on that sector and ruined it, a solid-state drive's flash memory cell may have worn out, or the hard drive may have had other defects or wear issues that caused the sector to become physically damaged. This type of sector cannot be repaired. A logical -- or soft -- bad sector is a cluster of storage on the hard drive that appears to not be working properly. The operating system may have tried to read data on the hard drive from this sector and found that the error-correcting code (ECC) didn't match the contents of the sector, which suggests that something is wrong. These may be marked as bad sectors, but can be repaired by overwriting the drive with zeros -- or, in the old days, performing a low-level format. Windows' Disk Check tool can also repair such bad sectors. Causes of Hard Bad Sectors Your hard drive may have shipped from the factory with bad sectors. Modern manufacturing techniques aren't perfect, and there's a margin or error in e

Next time computer was booted, it prompted disk errors, backed up as suggested.Computer going very slowly.Ran chkdsk /f on disk - said there are NO ERRORS and nothing corrected.Computer runs fine for a few mins, then slow again, then more messages saying errors on disk, backup data.Have run spybot and scanned disk with AVG just in case I have some sort of virus but not really getting anywhere.Computer gets slower and slower until it stops working, then I have to boot into safe mode/network and can do things and all seems ok but when I try and reboot into normal mode, it all starts going slow again.Does chkdsk know better than windows o/s about disk problems?Running on a Toshiba laptop using Windows 7.Any help greatly appreciated!HELP!Debs 5 answers Last reply Jul 30, 2012 More about windows disk error chkdsk jajigJul 29, 2012, 2:47 PM Your disk has bad sectors run "chkdsk /r /x" it will scan for the bad sectors and mark them as not usable. fzabkarJul 30, 2012, 4:43 AM Your statement that "it prompted for disk errors" is a little ambiguous. Is it the BIOS or Windows that is complaining about errors? Sometimes the drive develops an excessive number of bad sectors, triggering a BIOS SMART failure. However, because these sectors have been reallocated (ie replaced with spares), Windows/Chkdsk is unaware that a problem exists.Try a comprehensive SMART diagnostic. Look for reallocated, pending, or uncorrectable sectors.
