How to deal with bad sectors in hard disk

If the bad sectors are initiated due to decrease of magnetization, the impairment is irreversible. However, if the difficulty is due to inconsistencies in parity checking bits, it can be amended by utilizing befitting programs that can rewrite and restore these bits. It comes under the hard disk recovery.

There are two built-in programs that you can use to repair bad sectors. One is the CHKDSK and a more advanced version of it called 'Scandisk’. You can rectify bad sectors by running the computer disk scan program on any Windows operating system like Windows XP, Windows Vista and Windows 7: 

• Open 'My Computer' and right click on drive volume which is suspected to have bad sectors. 
• Click on the properties option and select the 'Tools' tab in the window that opens. 
• Click on 'Check Now' under the 'Error Checking' section. 
• Then comes two check boxes in another window with ‘Automatically fix file system errors' and 'Scan for and attempt recovery of bad sectors'. 
• Select both the options and click on 'Start'. This is done when all the programs running in the operating system are stopped. 

Hard disk error message

Have you ever got the message saying ‘cyclic redundancy error found’, if yes then this error message comes due bad sectors that are present in the hard drive of the computer. It mainly comes when we overused and used old hard drive. Till now I think lots of questions comes to your mind, what are these bad sectors, what are their causes, how to fix them and so on. 

A bad sector on hard drive is a bodily damaged part which can no longer be accessed by the operating system. When this awful part occurs to be a region where you have retained facts and figures, you get the 'cyclic redundancy error' as the functioning scheme cannot get facts and figures from that district. To check for integrity of written data, parity checking bits are written while storing data on a hard drive. The facts and figures may not be read due to inconsistencies of parity checking bits that are verified while composing and reading facts and figures from a hard disk. 

The major cause for bad sectors is a decrease of magnetism of the hard disk surface in certain localities with time. Bad sectors may furthermore be caused by rapid physical shocks to the hard drive, rapid power shutdown and interruption of reading and composing procedures on the computer disk. A failing read-write head of a hard disk is another origin of bad sectors getting conceived. So hard disk repair is the only option left.

To solve "BOOTMGR is missing"

Restart your computer. Now check your optical drives, USB ports and floppy drives for media. Seldom BOOTMGR error occurs if your computer setup is trying to boot from a non-bootable disc. If you find this is the cause for your problem then you have to change the boot order in BIOS so the hard drive is selected as the first boot device. Sometime BOOTMGR error could be caused due to loose or unplugged power and data cables. So try to reset all internal data and power cables in proper way. Sometime due to corrupt hard drive sectors computer shows BOOTMGR error. For fixing it you can do Startup repair of windows operating system including Windows vista, Windows 7, Window 8. This type of installation will replace any missing or corrupt files, including BOOTMGR. If you face any problem while installing Windows operating system like Window 7, Window 8 etc. If the partition boot sector becomes corrupted or not configured correctly in some way, then Windows won’t be able to start properly and cause an error like BOOTMGR is missing in the boot process. The solution to a damaged partition boot sector is to overwrite it with a new, properly configured partition boot sector using the Bootrec command. Damage of boot Configuration Data can also be the cause of BOOTMGR error. For eliminating this you have to rebuild the Boot Configuration Data (BCD).You has to use Bootrec command to build the BCD. Check the hard drive and other drive settings in the BIOS and make sure they are correct. The BIOS configuration tells the computer how to use a drive so incorrect settings can cause problems, including BOOTMGR errors. There's usually an Auto setting in BIOS for hard disk and optical drive configurations which is usually a safe bet if you're not sure what to do. An outdated BIOS version can sometimes cause the "BOOTMGR is missing" error. For eliminating this problem you should update your motherboard’s BIOS regularly. Install upgraded Window which will fix all the missing files causing the BOOTMGR error. This type of installation will completely remove Windows from your PC and install it again from scratch. This action will certainly resolve any BOOTMGR error but before doing this it is always advised to make a backup all your data as this installation can remove all your data so by doing backup it can be restored. If you have followed the above steps and still you have the problem then you’re most likely facing a hardware issue. So in my opinion you have to replace your hard drive and then install a new copy of Windows.

BOOTMGR is missing

Sometimes when you restart your computer then your computer shows you the message “BOOTMGR is missing”. And also gives you the option to press Ctrl+Alt+Delete to restart the computer setup. This file is responsible for loading your windows operating system and if it missing then your computer won’t be able to load windows. There are number of reasons possible for this error message.

The most common reason for the BOOTMGR missing error is corrupted system files. Sometimes it can be caused due to operating system upgrade issues and corrupted hard drive sectors. Outdated BIOS (basic input output system) is also may be responsible for this error message. If your computer hard drive is not properly setup in CMOS then it will give you the same message. If the computer is booting from a non-bootable source then this error message comes. Damaged or loose hardware interface cable may also cause this error message. 

NTLDR is missing ?

Sometimes you can see the message on your windows XP computer setup. These messages are about NTLDR file that is responsible for loading your operating system, it is missing.

1. "NTLDR is missing Press any key to restart"
2. "NTLDR is missing Press Ctrl Alt Del to restart"
3. "Boot: Couldn't find NTLDR Please insert another disk"

Now, here comes the solution for the NTLDR error, which is given in easy steps as below;

• Remove all the external memory from your computer because sometimes it is responsible for this error message.
• Windows repair- You can repair your windows by inserting your windows installation XP CD. Insert it and rather than installing a window go for the windows repair.
• Downloading and running updates:  Sometimes this problem occurs due to your windows has been outdated. So you have to update your windows.

Computer not responding-2

Hardware issue:

Sometimes hardware is also the root cause of the computer setup freezing or not responding. For example recently if you connected some hardware on your computer than simply remove it temporarily to check whether, that particular hardware is responsible for the computer locks up. 

Serious issue with Windows:

Even after going thorough all this steps, even then if your computer is locking up. It means your computer has seriously encountered the problems of some important files of operating system being getting corrupted. So here you can install your operating system CD on you disc drive and run the repair option, and all the corrupted files would be restored. Nut I would recommend you all to create the back up of all your files before you do repairing of your computer. 

Hardware failure:

Even after doing the repair and re-installation of your operating system, still if you face these problems, than it may be caused of your hardware issues like your CPU, Mother board, RAM(random access memory) and power supply. If you have extra available parts or have a friend or co-worker with a similar configuration that is willing to allow you to test their hardware in your computer, try swapping these parts to determine if they are at fault. Otherwise, you will need to have the computer serviced.
