I have a UDF CD that I recently received, but I cannot use it.

The disc reads fine, but when I open it, I see a single README.txt, that tells me the disk is UDF-formatted, and I need a computer that can read the UDF format (the readme is on a secondary CDFS filesystem, it seems).

Windows 7 has UDF drivers (and I have installed a hotfix for UDF-related issues), but it is not detecting the UDF filesystem.

Is there any way to get Windows 7 to read and mount this UDF filesystem?

Open Disk Management (Start > Run > diskmgmt.msc). Check to see what volumes are present on the CD in the drive. If you can see the UDF volume and the CDFS one, then Windows is just mounting the wrong one. You may have to manually mount one of them (Right click > Change Drive Letter and Paths... > Add... > OK > OK) to see the "correct" one.

Wow, that was it. Thanks! – neersighted Jan 13 '13 at 18:25
Unfortunately, I don't know how to make Windows mount the correct one by default. You may want to ask that as a separate question if you consider that functionality important. – K.A Jan 13 '13 at 18:26
