Write Protection is a way to prevent data loss on a drive.
Drive Usage Exhaustion:
Drives write data to blocks. Blocks can fail or go bad based due to usage. USB drives have threshold for the number of good blocks to determine the health of the drive. The drive will write protect itself to prevent data loss when the number of good blocks is lower than the preset threshold.
Storage Blocks:
The drive keeps two copies of data on two different blocks. The primary and secondary block. The drive will go into write protection mode to prevent data loss when corruption occurs on both copies of the block.
