Consider UDFS as Windows can format partitions/disks using the UDF file system but you can only do it via the command line, you can then read and write to it as you would to a normal disk, I believe Linux and Mac's can access it just as easily as long as you don't set the version too high and it is common to all three OS's.
e.g.
FORMAT volume [/FS:file-system] [/V:label] [/Q] [/A:size] [/C] [/X] [/P:passes] [/S:state] /FS:filesystem Specifies the type of the file system (FAT, FAT32, exFAT, NTFS, or UDF).
/R:revision UDF only: Forces the format to a specific UDF version (1.02, 1.50, 2.00, 2.01, 2.50). The default revision is 2.01.
/D UDF 2.50 only: Metadata will be duplicated.
