try changing this in /kernel/drv/sd.conf sd-config-list= "", "retries-timeout:1,retries-busy:1,retries-reset:1,retries-victim:2",
to sd-config-list= "", "retries-timeout:1,retries-busy:1,retries-reset:1,retries-victim:2,physical-blocksize:4096", and if any of the other entries matches your disk/ssd and sets it to 4k, remove it. after that, update_drv -vf and try again replacing your disk. worked for me, even if update_drv tells that it needs to be rebooted. ignore it...
