What Is a bad sector and how can I repair it?

By Liz Cornwell | February 11, 2010 |

Bad sectors are little clusters of data on your hard disk that cannot be read. More than that, though, they are the potential to cause real damage to your hard drive (catastrophic failure) if they build up over time, stressing your read arm. Bad sectors are fairly common with normal computer use and the imperfections of the world we live in; however, there are several simple steps you can take to prevent HDD bad sectors and to repair any that you do have. Having bad sectors will not speed up computer performance as well. Here is a step-by-step guide.
What is a sector, and how are HDD bad sectors created?

A sector is simply a unit of information stored on your hard disk. Rather than being a soupy mass of fluid information, your hard disk stores things neatly into “sectors”. The standard sector size is 512 bytes.

There are various problems that can cause HDD bad sectors:

  • Improper shutdown of Windows;
  • Defects of the hard disk, including general surface wear, pollution of the air inside the unit, or the head touching the surface of the disk;
  • Other poor quality or aging hardware, including a bad processor fan, dodgy data cables, an overheated hard drive;
  • Malware.

Hard and soft bad sectors

There are two types of bad sectors – hard and soft.

Hard bad sectors are the ones that are physically damaged (that can happen because of a head crash), or in a fixed magnetic state. If your computer is bumped while the hard disk is writing data, is exposed to extreme heat, or simply has a faulty mechanical part that is allowing the head to contact the disk surface, a “hard bad sector” might be created. Hard bad sectors cannot be repaired, but they can be prevented.

Soft bad sectors occur when an error correction code (ECC) found in the sector does not match the content of the sector. A soft bad sector is sometimes explained as the “hard drive formatting wearing out” – they are logical errors, not the physical ones. These are repairable by overwriting everything on the disk with zeros.
How to repair bad sectors

Windows has inbuilt check disk tool, called “Chkdsk”. It is recommended to run this tool from time to time. It will scan the disk for errors, fix logical errors, detect and mark bad sectors, so that Windows will no longer try to use them. This way it can prevent your computer from becoming unstable.

There is a slight disadvantage, though – Check Disk may require a lot of time to perform its task. It depends on many things, like overall PC speed, number of files and folders on the disk, amount of RAM, and disk size. So it’s best to run Check Disk only if you don’t need to use the computer for some time.

Also Windows Chkdsk wants exclusive access to the computer. In most cases it will ask for a reboot and will run right after the reboot, so you won’t have access to your PC. Of course, you can always interrupt the process, but it’s not a good idea.

 

To run Check Disk do this:

  • Find the My Computer icon on your desktop and double-click it;
  • Find the disk you want to check, right-click it and go to Properties;
  • In the Properties dialog box go to Tools;
  • Click Check now;
  • A new dialog box will appear, check both options and click Start;
  • Most likely you will get a message that Check Disk wants exclusive access to the disk and wants to start right after your reboot. Click OK;
  • Restart your computer.

Preventing bad sectors

You can help prevent bad sectors (always better than trying to repair them!) by paying attention to both the hardware and the software on your computer.

Preventing bad sectors caused by hardware

  • Make sure your computer is kept cool and dust free;
  • Make sure you buy good quality hardware from respected brands;
  • Always move your computer carefully;
  • Keep your data cables as short as possible;
  • Always shut down your computer correctly – use an uninterrupted power supply if your house is prone to blackouts.

Preventing bad sectors using software

  • Use a quality disk defragmenter program with automated scheduling to help prevent head crashes (head crashes can create hard bad sectors). Disk defragmentation reduces hard drive wear and tear, thus prolonging its lifetime and preventing bad sectors;
  • Run a quality anti-virus and anti-malware software and keep the programs updated.

    ummm…. how exactly does defragmenting a disk on a schedule prevent hard bad sectors? i could be over looking something, but defragmenting basically moves data to be “congruous” (all in a row) so that its quick and easy to access, it will help decrease seek times etc, but preventing a hardware issue it does not. I guess it could help cut down on disc wear etc, and keep the head from being in use in times where its likely to get bumped, but that should be explained, not left for the user to guess?

    Defragmenting will reduce and/or help prevent “soft bad sectors” , not “hard bad sectors”. Think of it as virtual corruption versus actual physical corruption. Like if you scribble on paper with pencil you can still erase it – (soft). Crumple and tear the paper, and you have to replace it – (hard).
    When the computer is unable to read a part of your disk during Chkdsk, it may mark it as a “bad sector” because it is unreadable or corrupted from a virus, but still repairable.
    Repairing the file area with an anti-virus and putting it back into a healthy, fast working order can free it from a status of being labeled as a “bad sector”.
    If you have been lucky enough to repair bad sectors in this way you can free them up by doing another Chkdsk.
    This time, use Cmd by clicking:
    Start > Type Cmd > Right Click and choose Run as administrator
    Next, type: Chkdsk /b
    and hit Enter
    (note the space between the “Chkdsk” and the “/b”)
    This will perform another scan to check the files to see if they are actually bad (physically damaged) OR if they have been repaired. You can do this after getting rid of viruses and other malware, getting rid of junk files, defragging and getting everything else in working, clean order.
    It takes about the same length of time to do this Chkdsk, so I do mine before bed and check the log in the morning. (Windows 7 Chkdsk log is located at C:\System Volume Information\Chkdsk
    (if “C:” is the name of your disk you scanned).
    But don’t hold your breath. Bad sectors is never a good sign, and more often than not, it is unable to be repaired.

    Excellent article, I have some old PCs that i’ve neglected for a while so i’m gonna perform a Low Level format on them to clear the errors they’ve built up. So far, I’ve downloaded the tools from Seagate, hopefully it will make my old drive last longer… but first I need to make a backup! lol i’ve been using CCleaner to clear the Free Space, but I don’t know if that made any improvement to the drive.

    parag,
    its true man. you need to replace your hard drive. i had that exact same problem. note they will just you double the price to install the thing as well. i just bought the hdd on its own. simply a matter of unscrewing it. taking it out being careful only to handle the sides if you can then take it out and slap the new one in.
    keep your old hard drive. you could look into freezing it later on. you put the hdd in two plastic zip lock lunch bags and stick it in the freezer. after a day or 2 take it out and put it in a computer and if it works then recover what was lost quickly. you can only do this once i think but im not sure.

    My hp pavillion gv6 laptop , i guess , due to an abnormal start , stopped working. I was busy , so didn’t take a note . I left my laptop as such . Now that i tried reinstalling windows 7 using a cd or a bootable pendrive, it allows me to choose language , keyboard layout etc .when i click next , what it displays is ” Set up starting ” with the cursor arrow showing processor busy sign , and then goes on as such .Even if u leave it as such for a whole night , the screen would still show the same thing. Some friend of mine told me that it is a hard disk bad sector error and that the hard disk needs to be changed . What do i do now …..please please please help me out 🙁 ??

    can you explain to me how much of this is physical? what it all means exactly?
    “There are 72 bad sectors on the disk surface. The contents of these sectors were moved to the spare area.
    The drive found 348 bad sectors during its self test.
    There are 348 weak sectors found on the disk surface. They may be remapped any time in the later use of the disk.
    9192 errors occured during data transfer. This may indicate problem of the device or with data/power cables. It is recommended to examine and replace the cables if possible.
    At this point, warranty replacement of the disk is not yet possible, only if the health drops further.
    Problems occurred between the communication of the disk and the host 929 times.
    It is recommended to examine the log of the disk regularly. All new problems found will be logged there.”

    The info in this article is incorrect in several fundamental ways.

    Most importantly, there’s no such thing as a ‘soft’ or ‘logical’ bad sector, sadly. All bad sectors are, by definition of that term, ‘hard’ or hardware-level issues. They can be discovered by reply utilities such as CHKDSK whose “surface scan” option writes to each sector and then reads back to verify integrity. If a problem is detected, the sector is marked ‘bad’ and henceforth avoided by the file system.

    Because of the above, improper shutdowns of the OS will not and cannot cause bad sectors. That’s a misunderstanding on the article author’s part.

    Friends, if your system doesn’t starts nicely and displays errors like ”Error Disk Problem” ”No boot media found”
    thn Replace a new sata cable for Hard disk and if problem persist change the power cable of Hard disk. This would surely do the needful. I had this problem and also Dvd drive failure, Corrupted Windows.
    I’ve cured the above three problems with the mentioned procedure. 🙂

    it is true that defragmenting tools help the computer to be faster because data can be all in row, and of course this methode can halp to protect the hard drive.
    head crash can caused from touching the surface of the Hard disk , and if the head moving all the time to read or write data from different rows because the data which is needed not in the same row, then this can cause more heating and also not really stable moving.., specially in new hard disk the place between the head and surface is very small, and air is important inside to let the head fly over the surface, moving the head all the time to different rows can some times not be stable… in this case head crash can ocure. it is rarely to say that this is the reason of headcrash but it is possible to occure

    Sorry to correct this part of your article, but they can be repaired.

    In fact I’ve been doing this for long thanks to a russian software made by Dmitriy Promochenko called HDD Regenerator.

    This is the only software that can not only repair a heavily damaged hard drive but it will also recover entirely the data, not only repairs the bad sector it will also restore its information.

    I Don’t think so. There are many problem, the blue screen my be cause by your hardware, examble your ram or the harddisk mode.
    You can swap to IDE mode and try to install again.

    I used Auslogic Registry Cleaner and did the undoing demize of taking out COM/ActiveX reg keys when cleaning the hard drive registry. I then went on to defrag and this is when I noticed that there was a “bad health” showing on the defrag. I then, commensed to starting a chkdsk -r and this is when the command got to the 144168 file and froze. I now cannot boot my computer and I tried using the free recovery disk from Acer/Emachines and the disk works up to the point of recovering the hard drive. All of the options are greyed out and unrespondant to choices of going back to a factory restore. My question: will a full restore/recovery disk from the manufacturer fix this problem? Thanks for the input. Cheers to all.

    If you have bad sectors in your hard disk, running a program such as Microsoft CHKDSK or ScanDisk and performing excessive attempts to read the disk can make matters worse. Your best chance of successful recovery of your data is to take your drive to a data recovery specialist and allow them to examine the disk.

People are always claiming to be able to fix bad sectors (and I’d have to agree with the guy who said that “bad” usually means “physical” to almost all PC techs and not some file system or partition error) and there are still plenty of kooks that believe that the “HDD Regenerator” (and others) can fix damaged surfaces. The explanation offered was even more ridiculous, implying some magical, vibrating magnetic fields were used. Fixing the disk with a program is like trying to program a pothole in the street to be filled – it ain’t going to happen.

    I have had power surges cause bad sectors on a drive, too. They usually differ from the most common by not increasing in number over time, the sure sign that the drive is dying and needs to be replaced. If the number does not increase, partitioning around the bad area works well.

    Pablo Zacheo,
    Not going to happen. That junk software only unmarks the clusters so that they look normal to the system. If they are readable, the data is then accessible. That can happen at times, sometimes due to simple factors like temperature.

    But the program does not “fix” anything, the areas are still unable to reliably hold data, and relying on them will lead to heartache. It would be irresponsible to assure a user that a drive that was “repaired” with that program or that the drive was all right to use for sensitive data.

    I have 160 gb hdd with 4 partitions. In partition c when i check for error I found that i have 8 kb bad sectors in the c: drive. All other partition have no error. I have followed the process. Everything is working fine but when i check for effor it is showing that error.

    Is it a matter of regret for the little amount of bad sectors?

    Sir I have given my PC to a repair shop for fully formating the PC and installing a new windows.
    My PC was working before that and when I bring it back from shop the problems occurs about starting up the PC. It is not starting.
    The man of that shop told me that it is about bad sectors in HDD .
    What is the solution for that.
