OWC Express 1M2 disconnects when writing
I have just purchased an OWC Express 1M2 and populated it with a Samsung 990 Pro 4TB M.2 SSD.
I am on a Mac M1 Studio Max, using the rear thunderbolt ports.
I am running Tahoe 26.3.1
I have managed to copy a small amount of data onto it, but when copying many GB or files it routinely disconnects within about 30 seconds.
I can read files fine.
When I try and tun Apples Disk Utility and run a First Aid check, the drive will disconnect within about 30 seconds.
I have replaced the thunderbolt cable with a good quality third party cable, with no improvement.
Sometimes when I connect the drive, it can't even browse the contents.
Connecting it to one of the front USBC ports seems to work fine.
Could it be a power delivery issue?
Any ideas of what the problem could be?
