My disk was an Samsung 8 TB SSD an 870 QVO with 8000 GB. Returned it. With the 870 QVO 4000 GB model I had no problems. Hard to say is it MacOS causing the problem or was it the hardware. I assume it was MacOS, because I first got a replacement disk, but it had the same problem:
initialising
partitioning as APFS or HFS+ (tried both)
first I could write and read to disk
after first removal from USB port, they didn't reconnect again
both new disks
