Analysis of Hard Disk Bad Sector Part 1 5
Analysis of Hard Disk Bad Sector Part 1 5
Sector on a computers disk drive that can not be used due;
1. Operating system inability to successfully access it (bad sectors) or Soft Bad
2. Permanent damage (physical damage to the disk surface) or Hard Bad
Soft bad have multiple patterns. The pattern of bad sectors, related to the degree of damage the hard disk. In my opinion, soft bad can divided into three types;
1. Operating system inability to successfully access it (bad sectors) or Soft Bad
2. Permanent damage (physical damage to the disk surface) or Hard Bad

Soft bad have multiple patterns. The pattern of bad sectors, related to the degree of damage the hard disk. In my opinion, soft bad can divided into three types;
- Bad sector beginning
- Bad sectors expanded
- SMART Failure Predicted on Hard Disk
1. Bad sectors beginning
Bad sectors beginning is for the first time, sectors on a hard disk can not be used or OS inability to successfully access it. Bad sectors beginning, occurs in one or two sector. Why first bad happen only one or two sectors....? Bad sectors beginning, can occur in drive C, D, E, F. Read more about bad sectors beginning. Analysis of Hard Disk Bad Sector - Part 2/5

| OS = Win XP, Capacity = 80GB, Bad on = drive C, Total bad found = 1, OS failed to load |
 |
| OS = Win XP, Capacity = 240GB, Bad on = drive C/D, Total bad found = 2, OS failed to load |
 | |
| OS = Wn 7, Capacity = 320GB, Bad on = drive E, Total bad found = 2, OS can access |
Problem = BSOD stop 0x00000074, OS = Win 7, Cause = Bad sectors on drive C
Problem = BSOD stop c0000218, OS = Win XP, Cause = Bad sectors on drive C
Many people do not realize, cause the OS is corrupted due to bad sectors. When the operating system fails to load, the efforts made are; repair system start-up, system restore, last known good configuration, repair registry, enter from safe mode, etc. When all the efforts have always failed, the final solution is to install fresh copy of the Operating System.
Operating System is corrupt, can be caused by many factors, viruses, user mistakes, corrupt registry, bad sectors, etc. If the OS is corrupted due to bad sectors, install fresh copy of OS was the wrong decision.
Based on experience, install fresh copy of OS (on the hard disk have bad sectors on it), the OS can survive for several weeks. The bad news is, the Operating System will return corrupt and the number of bad sectors on the hard disk will be growing (bad sectors will be expanded).
2. Bad sectors expanded
Sometimes we do not realize, cause damage is hard disk bad sectors. If solution is format and install fresh copy operating system, bad sectors beginning, will expand. Bad sectors expanded is widespread areas of bad sectors.
There are two patterns of bad sectors expanded
a. Bad sectors expanded has an random pattern
b. Bad sectors expanded has an regional pattern
a. Bad sectors expanded has an random pattern

3. SMART Failure Predicted on Hard Disk
S.M.A.R.T. (Self Monitoring, Analysis and Reporting Technology). SMART Failure Predicted on Hard Disk means there is severe damage in the hard disk. Severe damage in the hard disk, meaning;
- Severe damage to the front of hard disk sector
- Severe damage to the back of hard disk sector

- Severe damage to the front of hard disk sector
- Severe damage to the back of hard disk sector

Damage to the hard disk does not happen quickly, but through several stages. When damage occurs, system will give a warning. If the warning can be translated very well, hard disk damage can be prevented. However, we realize the bad sectors after, there was severe damage in the hard disk. Analysis of hard disk bad sectors aimed to prevent damage to the hard disk becomes more severe, with earliest possible detection of bad sectors in hard disk. Aware of bad sectors beginning are major key to prevent hard disk damage.
