Microsoft acknowledges Windows 7 Blu-ray burning bug

Microsoft has acknowledged that there is a bug in Windows 7 when users try to burn data onto a blank Blu-ray media. The burning process fails and an error is presented when trying to burn more than 23GB of data onto a single layer BD-R(E) disc, or 46GB to a dual layer disc.

“The disc wasn’t burned successfully. Make sure that you have the latest firmware for your CD or DVD burner installed, and then try again,” the error reads.

Microsoft has acknowledged that a flaw in the Windows 7 operating system causes it to miscalculate available capacity on blank Blu-ray media. “To work around this issue, do not attempt to write more than 22GB of data onto a BD-R Single Layer disc or 45GB for a BD-R Dual Layer disc,” Microsoft’s material reads. This “occurs because Windows 7 does not calculate the write capacity of BD-R correctly,” according to Microsoft.

The problem comes up when you try to burn more than 23GB of data to a single layer BD-R(E) disc, or 46GB to a dual layer disc. The burning process fails and the user is presented with an error message.

No word on when this problem will be fixed, so in the mean time, avoid burning to these discs or use an alternative solution for your burning needs.
