Hello I hope, that this is the correct mailinglist... if not, pls let me know... So, it seams, that there is a problem with the samsung t5 and t3, those ssds are just samsung 850 with an usb-c adapter. I wrote a mail to linux-ide, but Damien Le Moal suggested to me to write it to the maintainer of uas.c... My idea was to patch this in the ata_device_blacklist in libata-core.c, but since this seams not to be the solution, i have no idea how to do it... So, it would be nice, if someone how knows what he is doing could have a look at it. Sorry for my poor english. I hope this helps somehow to fix the problem. Best regards Sven Hugi
