Hi guys, I'm on the list and I read it all the time so no cc required.

Well, it is working, I rebuilt the parity a few times, and I the=20
reconstructed RAID twice...=20

The error messages still appear, but, everything is working, I'm happy
with that, as long as my data is safely copying from one disk to the
other.

Should I be concerned about this?


I included this in sys/dev/ata/wd.c with other similar entries.

        { "ST3160211A*",
          WD_QUIRK_FORCE_LBA48 },

Could it be the other quirk? The WD_QUIRK_SPLIT_MOD15_WRITE thingums?
Let me know if I must try this.

Thanks in advance.
