Q: Can't read a DVD formatted as UDF

I have a problem with my Windows 7 ultimate.

When I put a dvd-r disc formatted as udf to my dvd drive and go to My Computer, I can see that 3GB of data are on DVD, but if I clic on it it is empty.

In Disk Management I can see a partition on the disc, but in RAW format.

The hotfix didn't install.

The version of the udfs.sys is 6.1.7601.17514.

On the *SAME* machine and DVD reader, under a virtual Windows 7 (Virtualbox), with the *SAME* disc, in Disk Management I can see a partition on this disc in UDF and can be read with success.

The virtual machine is made with images on ModerUI.

The version of the udfs.sys is the same: 6.1.7601.17514.

I don't have any burning software on the phisical machine.

I have also installed the same release of VirtualBox under the virtual machine, to see if this software can create some problem: no, the disc is always in UDF format and can be read with success.

Can anyone help me?

Many Thanks

I understand the inconvenience that you have to go through due to this DVD issue. There could be several reasons for causing this issue, depending on the context. However, let’s work together to get this problem resolved.

However, before we proceed I would require some more information to assist you better.

2) Is this confined only to a specific DVD?

3) What is the make and model of computer?

I would suggest you to install this Microsoft hotfix and check if it helps.
