udftools-2.3 how can i config read-only in windows

Asked by kongqing on 2021-04-10

Hi all,
    I've got new 64GB USB flash stick and decided to format it to UDF. using udftools-2.3 tools,
" ./mkudf --media-type=hd --blocksize=512 /dev/mmcblk0p1", mount /dev/mmcblk0p1 /mnt/sdcard/ -t udf -o rw,noatime,
sdcard is readable-writable under Linux and Windows 10. However, i wonder sdcard works readable-writable under linux, but readonly in windows 10. what can i change for it?

So to clarify. Everything is fine in Ubuntu but Windows has a problem? Is this the case please?

 everything is fine(reading and writing) in linux(arm64-dev) and windows(win10). However, I wonder it's read-only in windows. when i use windows format commands, "format E:/fs:udf /R:2.01", the sdcard works fine in windows, but in linux(arm64-dev) just support reading.

Hi all,
Does mkudffs(mkudffs-2.3) can configure permissions for whole partitions.
what i need is that it's read-able and write-able in Linux, and it's read-only in windows or mac.
need your help, tks.
Best Regards.
