I assume if you just leave the SoftRAID Application open, it will eventually give "The SoftRAID Application must quit" message. Is this always after the Monitor has gone to sleep?
If you set the Monitor to Never sleep and disable Screen saver, does it not happen at all, take longer to happen, or never happen? I would appreciate the information. This bug is annoying but not widespread and hard to reproduce in the lab.]]></content:encoded>

Sorry this has been a hassle. Weird how this process was actually more reliable under FireWire than under Thunderbolt!]]></content:encoded>

                        <content:encoded><![CDATA[I should have gone into a little more detail, I was flying out the door at the time. Now that I think about it, this event looks like it happened the moment I woke my iMac up back from monitor sleep. So my guess is that this was almost surely triggered by the computer, surely not by the drives, and probably not by the Thunderbay itself, due to the fact that it coincided with a computer process. Does this sound logical?

Now, you say "This was a hardware event", what do you mean by that?

Moving Forward: I had been going for 3 passes, so I will do one more. You mentioned that the final pass writes all Zeros. I assume that means that if I choose "1 Pass", it will zero them out in the process? If all the disks make it, I will consider it good to go. 48 Hours.

My only concern is whether this "unmount on wakeup" issue could continue to plague me in day-to-day use later. I do some very long renders and encodes, I'm crossing my fingers that this isn't a sign of hiccups from the OS to come later on.

BTW: Thank you for all you help, you've helped me out a great deal, I know I've been a bit of a squeaky wheel.]]></content:encoded>

About 5 days into the test (most of the way through pass 2), the system unmounted the bay, giving me 6 dialog warnings of "This disk is unreadable" (which, of course just means it got disconnected and reconnected). And unlike the older version of SoftRaid, when I restarted the Certify, it didn't ask me to continue, but just restarted from scratch.

So I guess that's another 6 days? I've been at this for almost a month now.]]></content:encoded>

But you want to do at least a 2 pass. The reason is the last pass is always zero's. Zero's are the default state of a disk, so you are not exercising it this way. A two pass at least has a random pattern on pass 1, then zero on pass 2.]]></content:encoded>

I think for the sake of testing, instead of doing 3 passes all at once, I'm just going to do a single pass multiple times. That may be a better strategy when working with larger drives like this. It shows a single pass taking just under 48 hours.]]></content:encoded>
