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...
