UDF Format for Hard drives

[boogle]

So I have been looking into dvd udf format lately and was curious what the reasons for not using it for hard drives. It read write and crosses perfectly with mac and pc. Why is it not a format option for hard drives?

Just... don't. Read-write UDF probably isn't guaranteed to be reliable on any OS. Cross-OS compatibility... doubly so. Even if it did, performance would probably suck because most OSes don't support UDF 2.50 or later. Mac OS X only supports 1.50, and Windows prior to Vista won't do read-write UDF at all without third-party software.

If you want a cross-platform file format, sadly, the only choice is FAT32. Of course, since FAT32 performance inherently sucks (by design), I wouldn't suggest it for an audio or multimedia drive. There's really not a good choice for this. The best choice is probably to copy the data to a FAT32 volume for exchange with a different OS, then copy it to a better native volume format for actual use (NTFS on Windows; HFS+ on Mac OS X; ext2, ext3, Reiser, fs du jour on Linux).

Sigh. If only everybody supported LinLogFS.
