4tb external hdd on raspberry pi model 4 running 4.6

Has anyone had luck with formatting to 4tb fat32? mine is maxing out at 2tb on my external hdd

Is the drive partitioned as MBR or GPT? As far as I know, only the latter supports FAT32 partitions with more than 2TB (by using 4k sectors rather than 512MB ones).

That said, why do you want to use FAT32? If you need Windows compatibility, NTFS and ExFAT support >2TB partitions and can be read and written to in Linux / Retropie. If you don't need to use the drive in Windows, just format it with a Linux file system like ext4.

The package exfat-fuse is needed to mount ExFAT partitions is already installed in the official Retropie image. If you want to format ExFAT as well, you'll have to install the package exfat-utils manually with the command sudo apt install exfat-utils. You can use mkfs.exfat after that (make file system).

NTFS should be fully installed out of the box in Retropie.

See this topic.

@mitu I deleted the value listed but still no go, the pi won't see the usb at all now

@Buckey-Jaw If you remove the usbromservice, then you need to manually mount the disc - https://retropie.org.uk/docs/Running-ROMs-from-a-USB-drive/#configure-fstab-to-automatically-mount-usb-drive.

@mitu ran ls -l /dev/disk/by-uuid/ to get my UUUID of B210AED310AE9E3B on sda1
ran sudo nano /etc/fstab to add UUID=B210AED310AE9E3B /home/pi/RetroPie vfat nofail,user,uid=pi,gid=pi 0 2 on the bottom
now getting failed to mount home/pi/retropie

I verified the drive has the retropie-mount folder

BTW thanks for all the help, it's greatly appreciated

If your partition is formatted as ext4, then you need to replace vfat with ext4 and also replace the mount options accordingly.

UUID=B210AED310AE9E3B  /home/pi/RetroPie      ext4    defaults,noatime 0       2

Since this is manually mounted, you don't need a retropie-mount folder (this is only used by the auto-mounting done by usbmount) and you need to manually copy the contents of /home/pi/RetroPie to the disc - this is explained in the documentation page.

@mitu ahhhhh, I was waiting on the auto copy, it's formatted as ntfs, is that an issue?

You'll have to decide what format you have on the disc - is it ntfs or ext4 ?
Please use the documentation and follow the instructions - you have to choose one of the methods described there and take into account what filesystem you have.
