a) why not in original SATA or ATA/ATAPI-7 Specifically for Serial ATA, the SATA Revision 2.5 specification is a single integration of Serial ATA 1.0a in addition to much of the Serial ATA II material, including errata and design guides. The ICRC update was simply applied to SATA Revision 2.5 with the understanding that this new specification would replace the older set of documentation, which leads to little need to update the old documentation when it is getting replaced. b) the risk of using SATA that does not have this feature, c) how are SATA CRC errors report by original SATA devices that did not implement this feature? The change was specific to allowing ICRC usage for reporting interface CRC errors with Multi-word DMA and PIO protocols, previously it was only allowed with the Ultra DMA protocol. Since this behavior was not allowed prior to the change for either PATA or SATA, the impact of reporting interface CRC errors with these other protocols should not be specific to the transport.

Thanks for the information. Looks good to me for future SATA. But the proposal doesn't answer the other questions: a) why not in original SATA or ATA/ATAPI-7, b) the risk of using SATA that does not have this feature, c) how are SATA CRC errors report by original SATA devices that did not implement this feature?
