Almost no SD support the DRM features, according to Wikipedia.

(Still doesn't change the point, though. SDs are probably designed with internal firmware)

Ext3 and RAID: silent data killers?

That's not what Wikipedia says—they say few devices support CPRM. Which is more-or-less true—almost no devices in the western market use CPRM, while in Japan every single device does (it is required as part of i-Mode, which is mandated by DoCoMo).

As for firmware, the SD card interface (available for free at www.sdcard.org defines accesses in terms of 512-byte “logical” sectors, practically mandating the card to implement a flash translation layer.

Doh, of course.

I read "devices" as the SD cards themselves.
