did you try this:
Maybe this will show some clues?
Yes, but what should I be looking for?
Before it said:

But now it seems to have magically fixed itself, so says:

Pretty much as expected in other words. Before it was degraded, now it's not.
But the "Disk Read/Write Error" status was reported even after I detached the drive from the mirror, removed it from the tray and re-inserted it without attaching it to the mirror.
In other words, the "Disk Read/Write Error" status appears independent of the mirror.
I have posted more in this thread
http://forum.qnap.com/viewtopic.php?f=2 ... &start=330 as it was more to the point on my problem. I want to avoid double posting and ask to continue discussion there if you have more suggestions. Thanks.
