Same here, Macbook Pro 14' 2023 ( Sonoma 14.1). Icy Box Hub with NVMe Slot the 1TB is not recognized. Older 250GB shows up. Different cables, formatting to AFPS, different ports, powering external, Nothing did work.
Apple you have a serious problem, here !!
It is up to the third party manufacturers to make their products compatible with one another. In your specific case, you are using a third party hub along with a third party SSD. In order for macOS to even recognize the SSD requires that the SSD works in the Ice Box Hub. Have you confirmed these two items work together by testing on other computers, especially a Windows or Linux based system?
How is they Icy Box Hub connected to the Mac? Need specific and exact links to the cables & adapters used since they may make a huge difference, plus a link to the Icy Box Hub you are using since I don't know what you have and there are multiple possibilities. Also, what it the exact make & model of both SSDs....are they installed into this hub or do they have their own separate adapter/dock/enclosure? The 1TB NVMe and the older 250GB one? This is also extremely important to know. Not all SSDs work with all computers, hubs, docks, adapter, or enclosures. Yes, theoretically they should, but in my own personal experience this is not always the case.
Make sure to disconnect all other external devices in case one of them is causing a problem.
I've been supporting Macs for my organization for over 20 years and I have seen numerous third party devices not function with a Mac even though they should have worked perfectly fine. It is not something new. Maybe Apple is somewhat to blame at times, but I'm sure some of the third party manufacturers also have at least equal or more blame for having a product which does not function with a major brand computer. FYI, I have used Icy Box SATA sleds without issue on Macs, so I know that Icy Box can make a good product....are all their products good? I don't know. My guess the issue has something to do with the SSD being used or possibly the cable being used or how everything is connected.
I suggest you start your own thread so we can try to assist you with your issue so we don't lose focus on the OP's issue which may have a completely different reason for failing. I've just outlined multiple reasons for your failure, but that only scratches the surface of possibilities since there could be issues with third party software or other configuration issues.
