No matter how well designed or implemented the system is, there is still one very complex factor that causes most RAID array problems we see – the human being. Mistakes are easy to make and the more complex the systems become, the more potential there is for mistakes to occur
Example of things that can cause you trouble :
- Multiple drives can fail in an array – it's improbable
- Software Corruption:
accidental erasure or reformat, virus infection, power surge, etc.
- Hardware Failure:
damaged motors, actuators, bad controllers, head failure, etc.
- Deliberate Acts:
computer crime, vandalism, sabotage, etc.
- Arrays are normally boxed in a single case, so physical damage can affect multiple drives and the control electronics
- Deleted Files.
