Summary: Write Caching: Drive says "I have written your data" when it hasn't. (A bad thing!) Has not by definition anything to do with: Tagged queueing: Ability to reduce transaction latency by sending more than one request to the drive at a time. The request may be handled out of order by the drive. (A good thing!) and: ATA != SCSI. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
