Hello, Since the ntfs-3g(8) driver has very poor performance with USB (and the bottleneck is the driver, since formatting and using the device as an UDF one the writing performance, even if not tremendous, is improved) I'm trying to find if UDF can be used as a common filesystem to allow to read---here---the same USB connected disk both under NetBSD and under Windows.
For now, the disk formatted under NetBSD with newfs_udf(8) is not recognized by Windows (8.1). The reverse: the disk formatted under Windows for UDF 2.01 generates errors: "UDF mount: disc not properly formatted or damaged disc (rootdirs failing)" and the mount fails. What is different is that the Windows selects 2048 bits as block size, while newfs_udf is setting 512 bits. Furthermore, fdisk(8) shows no MBR when using newfs_udf(8) while the Windows formatted shows the first pseudo partition as a 238 aka "GPT Protective MBR". Has anybody managed to have an USB disk (it's a 2To) to be readable both under NetBSD and under Windows or whatever else?
