Hi Nathan, thanks for the reply. I'm not sure what kernel was there before. I was expecting to see traces in /boot but the only references are to 4.14.133.
Yes, the drives are Seagate 4TB ones, ID 0bc2:331a Thanks for the link to the known issues. I was looking at boot.ini so it seems I was heading in the right direction. I'm not sure if the copy I can see in /boot is active during the boot process or not, or if I need some additional steps to make that happen. I'm sure I can dig that out with the help of Google. I came to this page in a typically long and circuitous fashion after I noticed that the external drivers weren't spinning down anymore and discovering that hdparm wasn't working. Basic file IO was still ok. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1810215 Title: for Seagate USB drive enclosures, SAT (e.g. smartmontools) works on kernel 4.13 but not on 4.15 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1810215/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
