I've done some research, it looks like the ATA command which is being passed through the SCSI-over-firewire connection is IDENTIFY PACKET DEVICE (for errors with "a1" in the next to last byte of the hex dump) and IDENTIFY DEVICE (for errors with "ec" as the next to last byte). So something is trying to directly query the device (SMART check for drive health?), and apparently my enclosure chipset either doesn't support the passthrough, or the drive doesn't respond and is giving the abort.
I will attempt to followup with the enclosure manufacturer, but also if we could figure out what is triggering this query and disable it that would be helpful so I can use my media center again :) -- reading data from firewire drive stalls, ieee1394 errors appear in messages https://bugs.launchpad.net/bugs/440338 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
