发明名称 Rogue packet detection and correction method for data storage device
摘要 A method for detecting the location of falsely detected "good" data, or "rogue", packets in a data buffer is presented. A segment-level CRC is generated over, and associated with, a buffer segment, and recorded along with the segment data onto a storage medium. During data recovery, only packets that pass a packet-level error detection test are allowed in the data buffer. Once a data segment is complete, a segment-level CRC test is performed over the recovered segment-level CRC and the entire recovered segment data. The segment contains a rogue packet if the segment-level CRC test fails. Reed-Solomon syndromes are generated and used to locate and optionally correct the rogue packets.
