  • Questions on external drive mounting and backup issues

    Hello. I have a couple questions.

    For context, my setup is as follows:
    Libreelec 12.2.1.

    Raspberry Pi5 8GB, in a case with a relatively big fan and heatsink, CPU temps never going above 150f. Libreelec running on a 256GB Sabrent Rocket NVMe 4.0 SSD on an NVMe hat (yeah, overkill. So is everything else I do). One 10TB HGST HDD, in a USB 3.0 Sabrent enclosure.

    This setup has served me great the past year and a half or so. Recently I upgraded to Libreelec 12.2.1 from version 11 (I do not remember exactly which version it was). I made a backup of my configuration beforehand.

    My first question involves the HDD's. I allow them to spin down after a bit, to conserve energy and such. Then, when I go to access them again, they remount under a different drive letter. sda1 → sdb1 → sdc1, etc. This has the effect that any indications that I've watched an episode/series before disappears when it remounts under a different drive letter, which is one annoyance among others. You can actually see the old ones persist in SMB when you look at it on a Windows machine.



    I've experienced this on both version 11 and 12.2.1. In the past, I've added a cron job to touch the drive once per minute to keep it alive. That worked great and all, but I'd like to allow it to spin down to conserve energy and bring down the noise when not in use, while also having it re-mount under the same drive letter that they start with, ie, sda1. I was wondering if that was possible.


    For my second question, recently I tried to play some 4K content on this system, and discovered that the video/subtitles lagged massively, while the audio played at normal speed. After I elected to do a clean install of 12.2.1, the problem went away. But when I restore the backup that I had made earlier, the problem reappears. Now, I have more than 1 pi5, and I have replicated this issue on a totally different pi5, running the OS off of an SD card plugged into the USB port, and a thumb drive with 4K videos. Again, same behavior, smooth on a clean install. Laggy when I restore a backup.

    I could easily use both of these Pi5's, one with the backup restored and one clean, and go through each setting one by one to find the problem. But I was wondering if there was an easier way to compare what the difference are between installations, so I can find the root problem easier. Any help would be appreciated. Thanks!
