Block corruption or physical corruption occurs when a block on a physical disk BECOMES unreadable or inconsistent to the STATE that the data is UNUSABLE. Block corruption can be caused by many different sources; and therefore, it is difficult to find the exact reason of block corruption.

However, it is mostly due to human error with the use of software (patches) firmware, or hardware bugs.

You can avoid this by testing all the hardware and software patches thoroughly in the test environment. In addition, you can use mirrored disk to PROTECT your data.
