[smartmontools-support] self-test unknown failure

I have a brand new 8GB Toshiba N300 disk that was used as a replacement for
a ZFS array.

The disk had some seek errors as it was resilvering, but those errors have
cleared up. Self-tests are failing with "Completed: unknown failure". I
don't see any attributes that are undefined, so I'm not sure how to clear
the error on this disk. My OS keeps nagging me that the disk is bad, but
everything I can see says it's actually OK.

Is there a way to get a passing self-test, or clear the error on the disk
so it doesn't nag me anymore?

Thanks!
