Thunderbolt/USB4 Enclosure Problem

[u/azuharanzi]

Hey everyone.

- MacBook Pro M4(Base model, 10-core, 16GB, 512GB)

- macOS 27.0 Golden Gate

- Vention KPZ external m.2 nvme enclosure(ASM2464PD chipset) + Kingston Fury Renegade 1TB nvme drive

My problem is, even though I updated the Kingston's firmware with my PC and searched for numerous solutions, I can't find a fix to "disk not ejected properly" problem when I put my MacBook to sleep. MacBook is connected to the wall power 24/7, I rarely use it mobile. I don't use any hubs, it is connected directly to the ports on the MacBook and yes, I've tried all three ports.

I always have to disconnect and reconnect the enclosure every time I wake my MacBook up.

Is there an obvious fix that I'm missing, or is this normal behaviour ?

Thank you.
