在移动硬盘上使用 UDF 文件系统

Resation

　　大家的移动硬盘用什么文件系统？ ext3, xfs 等在 Linux 下支持得很好，可到了 Windows 下就无法访问（虽然有些工具可以读，但写却存在风险）。而 NTFS 是 Windows 下最好的文件系统，在 Linux 下却使用不便（虽然有 NTFS-3G, 但依然不是原汁原味地支持）. FAT32 虽然在 Linux 和 Windows 下的兼容性都好，但磁盘利用率不高，而且存在 4GB 的最大文件限制。

　　UDF 似乎是一个好的选择，但我在 Debian 下用 mkudffs 创建好的 UDF 1.5 版硬盘文件系统到了 Windows XP 下却根本不能被识别。据说 Windows Vista 以及之后的版本能够识别，但我没用过 Vista（也没用过 Windows 7）。再说现在大部分 Windows 用户也都在使用 XP.

　　用 Google 找了很久，没找到答案。哪位兄弟知道呀？

关注，如果udf能方便的用那就太好了

Why a computer might not read a particular UDF disk

Even if an operating system claims to be able to read UDF 1.50, it still may only support the plain build and not necessarily either the VAT or Spared build.

An example is Mac OS X (10.4.5), which claims to support UDF 1.50 (see man mount_udf), yet it can only mount disks of the plain build properly (it cannot mount UDF disks with a VAT at all, see Sony Mavica problem, and while it appears to be able to mount CD-RWs written with a Sparing Table, it does not read its files correctly in the case those files are actually remapped). The solution is to update the computer’s operating system (OS) to any later version of the OS, available without charge up to version 10.4.11 for both Intel and PowerPC Macintosh computers.

Similarly, Microsoft Windows XP Service Pack 2 (SP2), cannot read DVD-RW disks that use the Universal Disk Format (UDF) 2.00 defect management system. When you view the DVD contents by using Windows Explorer, you see an empty root folder. This problem occurs if the UDF defect management system creates a sparing table that spans more than one sector on the DVD-RW disk. Windows XP SP2 cannot read a sparing table that is larger than one sector. Windows XP SP2 can recognize that a DVD is using UDF. However, Windows Explorer displays the contents of a DVD as an empty folder. One can update the computer to Windows XP Service Pack 3, or to apply a hotfix to address this specific problem.
