You cannot write to a BD-RE disc or to a DVD-RAM disc on a Windows Vista SP1-based computer even after you disable the write-protection feature

Consider the following scenario:

  • You have a write-protected Blu-ray Disc Rewritable (BD-RE) disc or a write-protected DVD-RAM disc.
  • You disable the write-protection feature on the disc.
  • You insert the disc into a compatible drive on a Windows Vista Service Pack 1 (SP1)-based computer.

In this scenario, the disc is recognized as writable media. However, when you try to write to the disc, the operation fails, and you are prompted to insert writable media.

This problem occurs with all Universal Disk Format (UDF) file systems, such as UDF 1.5, UDF 2.0, and UDF 2.01.

Note: The write-protection feature is typically controlled by the notch on the DVD-RAM cartridge or by third-party write-protection tools.

There is a download that resolves this issue. See Hotfixes for details.
