I do remember seeing Doremi servers where the CRU power on behaviour was different so I investigated and found a datasheet on the CRU website explaining the meaning of the jumpers at the back of the bay. I changed them on a couple of non Dolby server and it worked. As the connection is just sata, I don't see why it shouldn't work on a 100, I reckon the CRU bays were shipped with the jumpers in that default position and then that changed, that's it.

I will have to check if that was the issue with the 100's CRU bay. Having a backup server would give a lot of peace of mind.

Steve: I would still consider going back to 4.3.5.9 but wonder if it is even worth it at this point. Are they both SMPTE-ready or is that as much a projector issue as server? This is the only real issue* I've had on 13 and whatever was going on seems more likely to be a media block (or projector) issue than system software. I would presume if a MB issue it might exist on older MB-ware as well.

The one other time I had something like this (on the older software) it happened AFTER a show had been successfully tested and when I started it for the audience just got white flashes. At least this time it showed up on testing.

* This aside, the only other issues I've noted on 13 were once in a while a deleted content was not delisted until reboot. And I once had some issue with a post production house bringing me something that would not play but some how caused the CRU drive to stop responding til reboot.

I've scanned the instruction sheet that came with a CRU DX115 6G bay and emailed it to Brad, in case he would like to put it in the manuals section. My recollection is that the only thing you can change with the jumpers is whether the orange light flashes on and off to indicate access activity or not. But I've wondered why you need to press the button to both mount and dismount with a CRU bay in a PC, but only to dismount with one in a DSS200 (i.e. it mounts a drive automatically on insertion). The instruction sheet says:

Jumper 1 - host activity LED pin / jumper 2 (ground): I presume this is to send a signal for a drive activity light operated from the motherboard, and that you connect these two to the motherboard if you want this facility.

3 & 4 - sheet says "reserved pins"

5 & 6 - HDD LED activity disable. If they're open, the amber activity light will operate; if they're jumped, it won't.

The unit ships with 3 & 4 jumped, and I've installed them both in PCs and DSS200s that way, without touching the jumpers; but the automatic mounting behavior is still different (it does in a DSS200, but not in Windows or Ubuntu).

You could probably configure autofs to automount those things for you if you want.

That's the generic DX115 guide. The DX115DC guide for 'Digital cinema' is slightly different. The frame has an 'auto spin-up' jumper. I've seen them being set with or without auto spin-up in different servers.

https://www.cru-inc.com/downloads/715/A7-115-0003_Rev3.3.pdf

Note there are version with and without the key lock. Also, previous versions had been spec'd SATA-2, while current versions are SATA-3 (6G). No big deal though, I have seen SATA-3 drives working in the old carrier systems as well.

Thanks Carsten, I was remembering right.
The PDF does not really show exactly where that power on jumper is - at least on my mobile. Is that the horizontal jumper?

That would partially explain it, but I have put the generic ones in DSS200s and they have auto-mounted. I suspect that the middle set of jumpers (described as "reserved" in the instruction sheet) is the auto spinup one, and that removing the jumper activates this feature. In fact, I dimly remember altering the jumpers on a replacement bay to match those on the failed one that I removed from a DSS200 before installing it.
