    Hard disk keeps "dismounting"

    My server is an Odroid 3 with an HD connected via USB with 57,000 music tracks. Has been stable for a couple of years.
    For the past few days, every morning I've had to remount my HD (via Putty) as no files can be found by the player. Windows Explorer can't see them either (Samba utility has been applied).
    I remount & all is well until the next day when the disk becomes not mounted. Overnight I do a rescan for new files in case that's relevant. I've always done this.

    Today I've reinstalled it all, as shown below. It seemed to be fine until the 4th track of an album stopped playing & no files found again. Disk had become unmounted again.

    HD checks out (SMART data good) & I'm using the same USB cable into the same USB port of the Odroid ie nothing physical has changed.

    Please can someone suggest a fix for why my HD won't stay mounted? Happy to provide more info if required.
    Many thanks
    Paul

    Thanks Roland0
    Here it is. I deleted the first few thousand characters as it wouldn't let me post it all. Not sure what I'm looking for...

    You can save the log as a text file and then zip it and then atach the zip file ?

    Have you tried another drive ? or another USB port ?

    I only have 1 drive but it seems to be working fine. I've plugged it into my PC & ran diagnostics - no issues reported.
    I've tried other ports from the Odroid too. I've mounted as HD1 & HD2 with no joy.
    I've attached the dmsg as a zip.
    Thanks for your help.dmesg.zip

    It has unmounted again.
    Here's a zip created since the earlier one.
    Can you see anything wrong?

    Shame!
    It's a mains powered USB drive.
