Abstract:
A system is provided. The system detects a dropped write from a hard disk drive (HDD). The system includes two or more HDDs, each being configured to define a data block spread across the two or more HDDs. The data block is configured to regenerate a checksum across the full data block during a read operation to detect the dropped write.
