14 DAY TRIAL // Microsoft is providing a fix to customers which have experienced problems when copying large amounts of data to a Blu-Ray disk on their Windows 7 computers.
According to the software giant, extremely poor performance is the indicator that users might have a problem.
The Redmond company reveals that copying over 10 GB of data to a Blu-Ray can take more than a day to complete, and even several days, depending on the size of the job.
Windows 7 customers can find that they’re affected, as can those with Windows Server 2008 R2. Upgrading to Service Pack 1 won’t solve this problem for either.
“Assume that you try to copy more than 10 gigabytes of data to a Blu-ray disk on a computer that is running Windows 7 or Windows Server 2008 R2. In this situation, the copy operation takes more than one day to finish,” Microsoft reveals.
“For example, you try to copy 40 gigabytes of data to a Blu-ray disk on a computer that is running Windows 7. In this situation, it may take more than three days to copy the data. However, this operation only takes about 12 hours on a computer that is running Windows XP.”
Another symptom detailed by Microsoft involves customers operating system dual Blu-ray disc drives on their machines. The second disc drive fails during the copy operation, the Redmond company notes.
The software giant already identified the source of the glitch, noting that:
“This issue occurs because of redundant error checking in the Universal Disc File System driver (Udfs.sys) code. This behavior slows the speed of the write operation after a specific amount of data is written to the disc.”
Not only this, but a hotfix is already available for download from Microsoft Support, with the Redmond company promising that it will be included into the second service pack for Windows 7 and Windows Server 2008 R2.
Windows 7 SP1 RTM and Windows Server 2008 R2 SP1 RTM are available for download here.
