Latest Patents

His latest patents revolve around the detection and correction of dropped write errors in data storage systems. The first patent describes a RAID system designed to detect and correct dropped writes. In this system, data and a checksum are written to a storage device, such as a RAID array. The data is initially classified as being in a 'new data, unconfirmed' state. Periodic checks are performed to determine if the data remains in this state. If a dropped write is detected, the state of the data is updated to a "single dropped write confirmed" state, allowing for error correction. If no dropped write is found, the data is marked as "confirmed good." Additionally, if the data was updated through a read-modified-write before the check, its state is changed to an "unquantifiable" state.
