Plan 9 Block drivers use sd(3)
What sd provides
  • fs interface,
  • partitioning,
  • a raw SCSI interface, and
  • sdscsi translates channel read/write requests into SCSI CDBs
What we (Royal We) need
  • compatability,
  • 64-/48-bit LBA support,
  • to control the fail lights
  • the ability to send raw ATA commands, and
  • more & improved drivers,
