What does HackerNews think of format-udf?

Bash script to format a block device (hard drive or Flash drive) in UDF. The output is a drive that can be used for reading/writing across multiple operating system families: Windows, macOS, and Linux. This script should be capable of running in macOS or in Linux.

I recall getting UDF cross compatibility required a bit of non-trivial work[0], did this improve recently?

3rd parties can write drivers for Windows, you know. A small, read-only FAT partition on a USB stick or SD card could contain the installable drivers necessary to read/write the rest of the disk.

However, that's unnecessary. The best option for a universal file system is UDF. Windows, Mac, and Linux all have full read/write support.

A sibling comment linked https://github.com/JElchison/format-udf which claims that it creates a whole-device FS which works across all 3.

There are several platform specific gotchas with UDF. If you want to use UDF on a drive, I suggest using the script at https://github.com/JElchison/format-udf. It takes into account the platform specific gotchas and formats a drive properly to be usable across Windows, Linux and macOS.

UDF is natively supported on all major OS.

I haven't used it in macOS but on paper macOS seems to be having even better support for it than Linux so you can give it a shot.

Lastly, you can use https://github.com/JElchison/format-udf for creating most compatible filesystem across different devices.

ISO 13346[0] is supported everywhere and can handle files larger than 4GB. It's used on DVDs, but it can also be used on a flash drive[1].
