EDIT: Yep. That one works. Thanks!

I will try again with a different adapter maybe (it being a USB 3.0 should not be a problem actually, but maybe I should look for a USB 2.0?)

If that does not work out, seeing as the thumbdrives have such unreliable performance, a small SSD drive should run reliably while giving the UCX II no problems with recognition, right?

And only the SD cards behaved so unusual.

Aaand also to just make sure and also, because I am at a loss as to what else I could do to make it work, I also wiped it again with "ones" and both times the same result:

Still the same error...

(BTW, thanks very much for taking the time on a sunday to reply - much appreciated, I am baffled..:) )

EDIT: Seeing as my notebook has a SC Card slot built in, I also tried the same procedure with the SC card only, leaving out the adapter. On the PC everything seems to have worked, but on the UCX II still the same error.

My Fireface UCX II says it can't read my memory card for DuRec.

I went for a combination of SC card and adapter: Sandisk Extreme Pro 128GB (recommended in a RME video or the manual, can't remember) and a ANKER USB 3.0 reader. The card was formatted on Win10 with MiniTool Partition Wizard. There is only one partition on that drive, FAT32, primary type.

Is the card reader the problem? What would I need instead? Or what might be going on?

UPDATE:
Never mind.  I switched the stick over to a MAC and used Disc Utility.  Instant Format and works perfectly (hopefully).  So far testing with 12 channels @192kHz = sitting at 50-51%

Did some benchmarks, works really nicely.

Benchmark 1: Recording 16 channels at 24 bit 192kHz for 20 minutes
HD: 69 to 71% 
R/W-Time: 72 to 76ms 
Errors: 0

Benchmark 2: Recording 30 channels at 24 bit 48kHz for 20 minutes
HD: 32 to 33 % 
R/W-Time: 72 to 73ms 
Errors: 0

Benchmark 3: Recording 8 channels at 24 bit 48kHz for 20 minutes
HD: 9% 
R/W-Time: 41ms 
Errors: 0

Now where I noticed how stable this runs I simply had the spontaneous idea, what you would think about such an extension. Sure, tools would need to be changed.

But thinking longer about this and reading your comment I have to admit, that I would even not be 100% sure, whether a DAW could handle such a big file and file operations might need a lot of physical and virtual memory so that my "spontaneous idea" might even be a bad idea. Ok, maybe not so cool than I thought initially.

Anyway, many thanks Matthias for your work and efforts / this video and having informed about these wonderful USB sticks, very useful ! :-)

Changing that would also mean updates required for all tools, software and the firmware of four devices. Lots of work, and IMHO not worth it.

And it's the other way round: the more channels you use, the quicker you write 100 files.

Basically 100 files of 2 GB = 200 GB max recording capacity. You can calculate that back on how much time in recording you get at low, medium and max channel count.
