Analysis of Hard Disk Bad Sector - Part 2/5

Why bad sectors, start with one or two sectors..?
Bad sectors beginning (first bad) is for the first time, sectors on a hard disk can not be used. First bad, occurs in one or two sector. Why first bad takes place on one or two sectors. 
Example;
Hard drive have three partitions (C/D/E). Ex; bad on drive D (bad sector position on = LBA 300,000,000). On LBA 300,000,000, there is a file movie (file name; naruto.mp4). User don't know, if movie naruto.mp4 corrupt because bad sector, but every time he play movie, in position ....... minutes, movie can't play. To play naruto.mp4, used application windows media player (on drive C). In this case, windows media player on drive C, I call Position A. Naruto.mp4, I call Position B. In this case, there are several possibilities can happen;

Possible No.1
Position B, is first bad. Bad on file naruto.mp4, not expand on drive C (WMP). So, hard drive, only have one bad sector (on drive D).

Possible No.2
Position B, is first bad. Bad on file naruto.mp4, expand on drive D (naruto.mp4). So, on file naruto.mp4 (on drive D), found two bad sectors.

Possible No.3
Position B, is first bad. Because, to play video used WMP, on drive C found new bad. Now, hard drive have two bad. One on drive C, and one on drive D.

Possible No.4

Drive D, is place to save movie files. To play movie, used WMP. On drive D, no bad found, but bad found on drive C. Characteristics for this case is, Windows failure to load, and show blue screen when computer start. So, on drive C, found bad (may be, one or two bad). In many case, I have meet, when hard disk check, found one/two bad. So, Windows fail to start because, bad sectors on drive C. 

1. Bad Sectors Beginning (first bad)
Bad sectors beginning is for the first time, sectors on a hard disk cannot be used. Bad sectors beginning, occurs in one or two sector. Bad sectors beginning, can happen, on drive C, D, E, and system reserved (windows 7, 8). When a bad sector in drive C, D, E, and system reserved, have different characteristics.



Region 1 = space occupied by operating system Windows XP, Vista, 7, 8. When drive C only contains the operating system, space required for XP = 2.7GB, Vista = 8.2GB, Seven = 7.5GB, 8 = 7.4GB. (Yellow)
Region 2 = space used for program files and my documents. After installing Windows, next process is to install applications. 25 GB is assumption of space used for program files and my documents. (Turquoise)
Region 3 = system reserved on Win 7, 8. (Bright Green)
Region 4 = free space (White) 
Region 5 = drive D, E, F (Plum)

Analysis of Bad Sectors Beginning
1. Bad sectors beginning in Region 2
See video below
When the computer is turned on, appears blue screen of death STOP: c0000218 (Win XP). The registry can not load the hive (file): \SystemRoot\System32\Config\SOFTWARE or its log or alternate. Registry file failure. This problem occurs due to many factors, one of which is a bad sector. To verify, use the "Bootable CD HDD Regenerator". When done check disk, bad sectors are found in, sector 63508318 = 32.516 GB (Drive C, Region 2), and sector 88229908 = 45.173 GB (Drive D, Region 5).

BSOD stop c0000218 on Win XP
BSOD stop 0x00000074 on Win 7

Bad sector No.1 (sector 63508318 = 32.516 GB)

Because there are bad sectors on drive C (Region 2), there will be a corrupt file registry software. It can be seen in the error message \SystemRoot\System32\Config\SOFTWARE. So, cause of STOP: c0000218 {Registry File Failure}, is a bad sector No.1
Bad sector No.2 (sector 88229908 = 45.173 GB)
Bad sectors on drive D, not resulting in damage to the system. Bad sectors on drive D result, a corrupt file on drive D.
Bad sector beginning, can occur in drive C, D, E, F. When bad sectors beginning is happen, we must immediately repair .
Solution for this problem, can read here Repair Hard Drive Bad Sector 2 or Repair Hard Drive Bad Sector 3

2. Bad sectors beginning in Region 5



OS = Win7, Bad on drive E, every times turn on show chekdisk

If bad sectors beginning in drive D, E, F, operating systems is function normally, as if there was no damage in the hard disk. Sometimes, we are not aware of bad sectors on drive D, E, F.
The characteristics of bad sectors on drive D, E, F (Region 5)
1. There is a corrupt file on drive D, E, F.
Assumptions; drive D, E, F are used to store data (docx, xlsx, pdf, mp3, video, picture, etc), and we found the corrupt file, it should be done checking your hard disk. To check for bad sectors, it can be done with the software HD Tune.
2. Found folder found.00 and sub directory
There are two type folder Found.000
  • FOUND.000, FOUND.001, FOUND.002, etc. Folder name is written with a capital letter. This folder mean; check disk can fix the problem on the disk, or no bad sectors (see picture)
  • found.000 with sub directory. Folder name is written with lowercase. This folder mean; check disk can not fix the problem on the disk, or found bad sectors on disk (see picture)

FOUND.000 folder (no bad sectors found)
After active super hidden and show FOUND.000 folder (see picture)
no bad sectors
found.000 folder (bad sectors found)
After active super hidden and show found.000 folder and sub directory, mean "found bad sectors on hard disk" (see picture)
folder found.000 and sub directory (found bad sectors on disk)

So, each turn on the computer, Windows always checks disk, it is likely there are bad sectors in the drive D, E, F. To be sure, check the hard disk with the software HD Tune.

3. Bad sectors beginning in Region 3
Bad sectors beginning in Region 3 are bad sectors beginning in the System Reserved (Windows 7 and 8). See the picture below;
Bad sectors on System Reserved (Region 3)

Windows 7 and 8, is designed with a very good system recovery. When computer starts, and found an error in the system, we can use the System Recovery Options. However, if the system recovery options can not fix the error, and the final solution is to install a fresh copy of OS.
When done install a fresh copy OS is detected, System Reserved = unallocated space, Type = none. This problem can be interpreted, there is a possibility, there are bad sectors in the System Reserved.
Bad sectors in the system reserved, very dangerous, because it was the leading sector. For Windows 7 (0-100 MB) and for Windows 8 (0-350 MB). Based on experience, bad sector in the system reserved may result, SMART Failure Predicted on Hard Disk. If there are bad sectors in system reserved, data on drive C, D, E, F, can be accessed normally.
System Reserved Windows 7 and 8

So, when install fresh copy of operating system, and found, System Reserved = unallocated space, Type = none. Should be checked hard disk, there is a possibility of bad sectors in 0-100MB on Windows 7, and 0-350MB on Windows 8.

4. Bad sectors beginning in Region 1
See video below

1. When the computer is turned on, appears blue screen of death STOP: 0x000000F4 and STOP: 0x0000007B.
STOP: 0x000000F4 and STOP: 0x0000007B, due to many factors. One of them is the hard disk bad sector. STOP: 0x000000F4 and STOP: 0x0000007B, means there is a bad sector on drive C, Region 1. To ensure the cause of damage, do the scan disk with Boot CD HDD Regenerator.
Blue screen of death. STOP: 0x000000F4 and STOP: 0x0000007B

2. When the computer is turned on, the message [Windows Root]\System32\hal.dll. Please re-install a copy of the above file.
Corrupt file system is caused by many factors, one of them bad sectors. To be sure, do the scan disk with Boot CD HDD Regenerator.
Hal.dll corrupt - Drive C, file system Unknown - Bad sector on drive C
3. When done repair Windows XP OS, with the Recovery Console, you can not logon to  C:\WINDOWS>
Can not logon to drive C, its mean drive C bad sectors. This case can occur on Windows XP, Vista, 7, 8

STOP: 0x000000F4, STOP: 0x0000007B, [Windows Root]\System32\hal.dll, and can not logon to drive C, is the error message if there are bad sectors on drive C (Region 1). Bad sectors in Region 1, could result in; corrupt operating system file and corrupt file system format (FAT32 or NTFS).
Solution for this problem, can read here Repair Hard Drive Bad Sector 2

5. Bad sectors beginning in Region 4
Bad sectors beginning, did not occur in Region 4 (free space drive C). Free space is a place spread of bad sectors.

Difference between bad sectors occurring in drive C and D/E/F
1. Bad sectors on drive C
  • When computer starts, a message appears: blue screen of death, STOP: c0000218, STOP: 0x000000F4, STOP: 0x0000007B
  • Corrupt file system. [Windows Root]\System32\hal.dll
  • Repair Windows with the Windows Advanced Options Menu is always failed, repair Windows with the System Recovery Options always fail, and the final solution is to install a fresh copy OS (assumptions; cause is not a virus).
  • We can not enter the desktop
2. Bad sectors on drive D/E/F
  • We can enter the desktop
  • When the computer starts, it always appears the check disk
  • Found folder FOUND.000, FOUND.001, FOUND.002, etc (to be sure, do check).
If bad sectors beginning is not repaired, bad sectors will expand. There are two patterns spread of bad sectors.
  1. Bad sectors expanded has an random pattern, read more here Analysis of Hard Disk Bad Sector - Part 3/5
  2. Bad sectors expanded has an regional pattern, read more here Analysis of Hard Disk Bad Sector - Part 4/5
