    Yes, a valid concern. I guess I didn't delve more because it's working
    fine on my copy of Windows 7 RC (on the same hardware) with no sign
    of error logs and pretty much the same perf as Linux with NCQ forced off.

    What I can do personally is plug in my SSD into my tablet PC sitting next
    to me and do a few more tests and get back to you all - it could be a couple
    of days. I know its still just one user (me) reporting though.

    FYI I had posted on the manufacturer's website/forums (quite active with
    a lot of owners) and got NO response indicating there aren't too many
    Linux users with this model - again "can't prove a negative" sort of way.

    In any case, the workaround (should anyone face this issue) is to simply
    add " libata.force=noncq " to the kernel boot options.
