It's not an error code in the MMC5 standard, though, so presumably it's a vendor-specific error code. Not sure why it would be writing to the disc though.. Maybe if the disc is mounted read-write it is doing last-access-time updates or something? -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from hancockr@...pamshaw.ca Home Page: http://www.roberthancock.com/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
