Important Facts About HardDisk Bad Sector Repairing

Utilities:
1. HD Tune Pro ( ‘Error Scan’ );
2. HDDRegenerator (repair ‘bad’ ) - found in Hiren's.Boot.CD.v9.5;
3. SystemRescueCd-x86-1.1.0 - http://www.sysresccd.org/Download ;

Method 1 : Suitable for System Recovering (an OS does not function at the moment)
1. Run HD Tune Pro - ‘Error Scan’; if ‘bad’ on hdd, they are reds and it shows position of bad; write on a sheet of paper the position of bad;
2. Restart computer;
3. If hdd is RAID or AHCI, enter BIOS ( F2 ) & choose for IDE master non-raid, save bios and exit;
4. Restart computer, F11 (or choose boot device), boot CD /DVD HirenBootCD 9.5;
5. Choose HDDRegenerator;
6. Scan from position - postition from point 1 or less;
7. After Restore, restart computer, F11, boot from CD SystemRescueCd;
8. Resetting bad sectors list ( partition is for ex. /dev/sda1 , for C: partition ):
9. ntfsinfo -i 8 partition => ntfs_size = “Dumping attribute $DATA (0×80)”/“Allocated size” line ;
10. ntfstruncate partition 8 0x80 '$Bad' 0 ;
11. ntfstruncate partition 8 0x80 '$Bad' ntfs_size ( ntfs_size from point 9) ;
12. Command exit ( or reboot ? ) - Restart computer;
13. If hdd was RAID or AHCI, enter BIOS ( F2 ) & choose IDE master how it was before of modification from point 3 ( for ex. AHCI ), after that save bios and restart ;
14. Enter Windows -> Start -> Run -> cmd -> chkdsk c: /r , ‘next start: Y’, restart computer;
15. After chkdsk finish , Windows restart automatically;
16. Enter Windows , view chkdsk results , My Computer - Manage - Event Viewer - Application - Search for Source - Winlogon (last record date) and there it shows what chkdsk was make;

Method 2 : Eliminate identified Bad Sectors of a HDD with Functioning OS installed

Start the "HDD Regenerator" Application

1. Choose the drive to regenerate
2. Enter the "Starting Sector" parameter. Leave this parameter equal to 0 if you want to scan the entire disk. Enter the sector value if you want to scan the disk not from the beginning. For example, you don't want to scan the first 5 GB of your hard drive to save time, because you know that this part of the surface does not contain bad sectors. In this case enter the offset equal to 5000 with 'm' following or 2560000 without 'm' following (number of sectors 5000x512=2560000)
3. Wait while the scanning is completed. If you use the unregistered version, you'll receive onscreen report about the possibility to regenerate your disk by means of the registered full version. If you use the registered version you can find the report about regenerated sectors in the hddreg.log file.

Software Description:

• Hard disk drive is an integral part of every computer. It stores all your information. One of the most prevalent defects of hard drives is bad sectors on the disk surface. Bad sectors are a part of the disk surface which contains not readable, but frequently necessary information. As a result of bad sectors you may have difficulties to read and copy data from your disk, your operating system becomes unstable and finally your computer may unable to boot altogether.

• When a hard drive is damaged with bad sectors, the disk not only becomes unfit for use, but also you risk losing information stored on it. The HDD Regenerator can repair damaged hard disks without affecting or changing existing data. As a result, previously unreadable and inaccessible information is restored.
  

Key Features:

• Ability to detect physical bad sectors on a hard disk drive surface.
• Ability to repair physical bad sectors (magnetic errors) on a hard disk surface.
• The product ignores file system, scans disk at physical level. It can be used with FAT, NTFS or any other file system, and also with unformatted or unpartitioned disks.
• Bootable regenerating diskette allows starting regenerating process under DOS automatically.
• Bootable regenerating CD can be created from the program and used to automatically start regenerating process.
  
  Review:
  HDD Regenerator is a hard disk driver regenerator. It can regenerates bad sectors by magnetic reversal. This technology is hardware independent. HDD Regenerator supports many types of hard drives and repairs damage that even low-level disk formatting cannot repair. Because of the way the repair is made, the existing information on the disk drive will not be affected!
  
  It's very easy to use HDD Regenerator to detect and repair bad sectors as well as regenerate hard disk drivers. HDD Regenerator enables you to create regenerating CD or Floppy to boot your computer. While It maybe out of date to use floppy nowadays and the software is not very valuable with its price
