The Register: CNet suckered by CPRM spin

(Other stories by Andrew Orlowski)

"As we suspected, the 4C Entity's damage control airforce has succeeded in scoring a direct hit. A report on the CNet/ZDNet media behemoth by CNet Staff Writer John Borland covers the recent CPRM on ATA furore, pitching it - as IBM and Intel strenuously - as a copy control mechanism for removable media."

"Alas, the author has ignored the fact that removable drives Zip and Jazz use the packet-based ATAPI cousin of the ATA specification, the standard used by fixed hard disk drives. What's under consideration by the T.13 committee are extensions to the ATA interface itself."

"And quite specifically, as examination of the proposed new calls will reveal, the interface contains parameters that ATA need but that ATAPI devices don't. Specifically, the sector start and offset information requested by CPRM on ATA is not required by an ATAPI device. ... Although IBM microdrives have been cited by both IBM and Intel as a raison d'etre for the new specification, extending CPRM to these does not require extending the ATA command set itself, merely a small and device-specific subset."
