[Solved] USB: Unrecognized mount option "uid=1000" or missing value

[lionel_Z80]

Hello,

Pi Model : Raspberry Pi 3 Model B Rev 1.2
Power Supply used: one 5V 2.5 A for the Raspberry Pi, another one 5V 2.5 A for the hub with the hard disk drive.
RetroPie Version Used: 4.6
Built From: retropie-buster-4.6-rpi2_rpi3.img
USB Devices connected: Logitech F510 Gamepad (RumblePad 2), iBuffalo classic USB Gamepad BSGP801, Logitech M105 Optical Mouse, HP Inc Elite Keyboard, Belkin USB F4U040 Hub, USB-HUB255W (Sanwa Supply), USB hard disk drive (160 GB)
Controller used: Logitech F510 Gamepad (RumblePad 2), iBuffalo classic USB Gamepad BSGP801
Error messages received: EXT4-fs (sda1): Unrecognized mount option "uid=1000" or missing value

I installed Retropie from the official image on a new SD card.

Everything works from the sd card. I then followed the guide to use an external hard disk drive (HDD). However, my ext4 formatted HDD is not mounted, even though it has the retropie-mount directory, and the owner is 'pi'. The same thing happen with an ext3 HDD. The error is:

[    7.373870] EXT4-fs (sda1): Unrecognized mount option "uid=1000" or missing value

If I do:

sudo mount /dev/sda1 /media/usb

Then i can see the USB HDD:

pi@retropie:~ $ ll /media/usb
lrwxrwxrwx 1 pi pi 4 Apr 28 02:14 /media/usb -> usb0
pi@retropie:~ $ ll /media/usb0
total 24
drwx------ 2 pi pi 16384 May 22 17:13 lost+found
drwxr-xr-x 2 pi pi  4096 May 22 17:27 retropie-mount
drwxr-xr-x 2 pi pi  4096 May 22 17:26 video

Using the exact same hardware and the same USB HDD, with a FAT32 file system instead of the ext4 or ext3 file system, everything works. However, I cannot reformat all the ext4 HDDs to FAT32, as some files are bigger than the FAT32 limit.

It seems similar to the problem mentioned in [https://retropie.org.uk/forum/topic/25875/usb-automount-not-working?_=1590162241275](link url)

It's a known problem - i still need to look into it. You can remove usbromservice and mount manually, or edit /etc/usbmount/usbmount.conf and remove the uid=1000,gid=1000 options from the line that starts MOUNTOPTIONS=
