Now Y'all Know Analysis Of Difficult Disk Bad Sector - Business Office 3/5
2. a. Bad sectors expanded has an random pattern
When a operating organization error, solution is to repair the operating system. However, when repair operating system always failed, the end solution is to install a fresh copy operating organization (assuming; cause of damage is non a virus). Format drive C and install fresh copy the operating system is not the best solution. We convey to think, bad sectors may cause of corrupt operating system. Based on experience, when cause of damage is bad sectors, format and install fresh copy OS, will worsen the damage hard disk, and bad sectors will expand.
Hard disk, divided into 3 sections
1. Front area (system reserved in addition to drive C)
2. Central area
3. Rear area
Spread of bad sectors, will deed forrad or backward (but more likely to deed forward), with irregular distribution pattern.
2. If bad sectors beginning in the central area
Spread of bad sectors, volition deed forrad or backward, with irregular distribution pattern.
Spread of bad sectors, will deed forrad or backward (but more likely to deed backward), has a regional pattern.
Bad sectors always initiated from a unmarried point (one sector). If the point is non immediately repaired, damage will hold upward to a greater extent than widespread. Bad sectors like a cancer growing on the hard disk. Widespread bad sector in hard disk, has an irregular pattern. Based on experience, bad sectors is growing very fast. Generally, we realize the drive of damage is bad sectors, after bad sectors were widespread. In this condition, work hard disks are not stable.
Bad sectors expanded
- Bad sectors offset inward front area (drive C or organization reserved), will deed forrad or backward but more likely to deed forward, amongst random pattern.
- Bad sectors offset inward key area, will deed forrad or backward, amongst random pattern.
- Bad sectors offset inward rear area, will deed forrad or backward but more likely to deed backward, amongst regional pattern.
- Bad sectors expanded, have two patterns. Random patterns and regional patterns.
- The spread of bad sectors (forward or backward), resulted in the SMART Failure Predicted on Hard Disk.
Why bad sectors expanded..?
Hard drive convey 3 partitions (C/D/E). Example, bad on drive D (bad sector order on = LBA 300,000,000). On LBA 300,000,000, in that place is a file motion painting (file name; naruto.mp4). User don't know, if motion painting naruto.mp4 corrupt because bad sector, exactly every fourth dimension he play movie, inward order ....... minutes, motion painting can't play. To play naruto.mp4, used application windows media thespian (on drive C). In this condition, every time, user opened upward naruto.mp4 file, bad sector volition expand, on drive D (drive file movie) in addition to on drive C (drive application to play movie).
What happens is, bad sectors will continue to spread in drive C and D. Analysis of Hard Disk Bad Sector aims, so that we can detect bad sectors early, to prevent further damage. More severe the damage, more difficult to process improvement, and more hard to rescue data. Prevent damage, more important than fixing. However, if damage has occurred, save the data is a major task.
