I formatted the drive on my Ubuntu laptop. It works fine when connected to the laptop.
I’ll format a USB drive and write some files to it and see if I can reproduce.
I installed btrfs-progs on Vero V:

Your btrfs-progs seems quite old. Which version of Ubuntu are you using? Have you tried formatting the drive on the Vero V?
I recently started moving all external storage to btrfs since its COW nature was more resilient during accident power lost.
A 512G micro SD card formatted on Fedora 40 with 6.11 works fine on Vero 4K with latest update.
I’m in the process to move to a 18T external drive. I will report back how Btrfs on that works with Vero 4K later.

Allow me to provide more updates after using btrfs extensively with Vero 4K from last month:
- For almost all cases, it works just like ext4 formatted one on this 18T external drive.
- While using FTP transfer (Server: vsftpd; Client: FileZilla), there would be occasionally speed drop during large file transfer. It can complete with no error, but slower than ext4 formatted one.
- In last week, a kernel error was hitting, probably due to a long aria2 seeding session. This renders the disk not recognizable by the Vero 4K. After rebooting, the system returns to the normal status, without any files lost. Errors from
dmesgwere printed like below:

I guess I will continously using btrfs on this external drive with Vero 4K for now.
