DVD-Drive suddenly cannot read any discs that are File System CDFS. System Information tells me that the driver is disabled. How do I enable the driver ? Thx. PS I see a couple of other posts with the same problem but answer not posted yet

To enable CDFS: 1. Open My Computer. 2. Right-click the DVD-ROM drive and select Properties. 3. Select the Recording tab. 4. Check the "Enable CD recording on this drive" box. 5. Press OK. NOTE: If you install 3-rd party recording software, you may not have the Recording tab. I don't suffer from insanity, I embrace it.

Don't have the Recording tab. I have a TOSHIBA DVD-ROM SD-C2502. It came pre-installed with the Acer TravelMate 550 laptop. Any other way of enabling the CDFS File System Driver ? Thx.

Thx - I don't require Recording tab. I'm trying to read discs in my DVD-Drive. Windows is no longer recognising File System CDFS discs I place in my DVD-Drive eg Music CDs, PC Games, Software like Norton Antivirus, Microsoft discs such as Wndows XP Home Edition, VCDs etc etc It is recognising DVDs for File System UDF The only thing I can see is that the CDFS File System Driver is disabled. I believe I need the CDFS File System Driver enabled to read CDFS File System discs (I could be mistaken, in which case I still have the problem reading CDFS discs)... Thx

I found this in the MSDN Library ... Perhaps the XP Service Pack 1 has disabled CDFS so that the DVD-drive is now only recognising UDF - in which case how do I enable CDFS again ? http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/base/cdfs.asp CDFS CDFS, or CD-ROM File System, is a relatively simple format that was defined in 1988 as the read-only formatting standard for CD-ROM media. Windows 2000 implements ISO 9660-compliant CDFS in \Winnt\System32\Drivers\Cdfs.sys, with long file name support defined by Level 2 of the ISO 9660 standard. Because of its simplicity, the CDFS format has a number of restrictions: Directory and file names must be fewer than 32 characters long. Directory trees can be no more than eight levels deep. CDFS is considered a legacy format because the industry has adopted the Universal Disk Format (UDF) as the standard for read-only media.

When you look in System Information you should also check to see if CDFS has been started. Mine also says Disabled under Start Mode but shows as having been started, and CDs play just fine. If the problem just started you might want to try using System Restore and see if that works.
