My question is related to the patch introduced in this post How to tell Linux Kernel > 3.0 to completely ignore a failing disk?

If the kernel is patched with this code what is the kernel parameter that need to be set to disable ata:2



  • Something like libata.force=1:disable. I'm not sure how to map ata:2 to the correct number, just try some numbers to figure out the correct one. Feb 27, 2014 at 16:01
  • Thanks for the tip, in the meantime I also found an answer from @Rmano on another thread [link] (superuser.com/questions/599333/…) "libata.force=2.00:disable". This generally works to disable the port but it seems my problem is slightly different as even with the port disabled I get "ata2 comreset failed (errno=-16)" and "ata2: link is slow to respond, please be patient"
