@mitu said in Usb drive mounting problems:

Just assign a letter in Windows to the partition and erase the folder on it.

So yeah, apparently that was the issue, that somehow a retropie-mount folder was also in the EFI partition:

Assigning letter H: to the EFI partition and checking through admin in powershell I can see that there is a folder structure and it looks the same as what I see on the desktop on the RPI400 when it fails to load the HDD. I just removed everything from H:

So let's see how it behaves from now on. If I don't come back to this thread asume that it was solved.

Thank you very much both of you for your help!

@themazingness https://retropie.org.uk/docs/Debian/ (at least that one worked for me on 20.04.1 LTS a few weeks go), though co do [final edit:] to build some additional (optional/experimental (can't remember which one, could have been lr-mame 2016)) packages, it was neccessary to install python 2 (which is EOL, and therefore not included with UBU20).

I figured it out.

Problem was I followed a tutorial somewhere that said to make a folder called retropie whereas the official instructions state to make a folder called retropie-mount.

"retropie" will in fact copy everything to the HDD, but it will also copy from the HDD to the SD.

"retropie-mount" seems to copy everything from the SD to the HDD but will not copy everything back to the SD.

"retropie-mount" is sufficient to mount the HDD and play games. I did not need to follow all the steps to manually mount the HDD as mine is going to be portable.

@squishykoishi said in Auto mount USB HDD doesn't mount, HDD does work:

As for /etc/fstab I'd probably ask something pathetically stupid about it, and would rather not waste time for people who need to answer more important questions/fix bugs or whatever :p

My local LUG had a motto - don't just ask to ask, ask directly. That's why the forum (including the Help & Support category) exists.

I ended up just putting all the ps1 games on my new 500gb HDD, so solved

It turned out that I was just using a cheap ass micro USB cable, when I replaced it with a quality one the issue stopped happening, thanks anyways guys

Awesome thanks so much for the quick reply!! Going to try this now :) Appreciate the assistance!
