I am trying to burn a data cd. The process of burning is completed normally but the cd is not accessible. When I insert the burned cd, the cd driver crashes. This happens only when I try to make a data cd. On the other hand I can make music cd without problems. My laptop is Sony Vaio VGN-CR41S and OS is Vista.

you might have to physically unplug the leads for this cd/dvd then plug them back this should activate the found new hardware wizard or
you might have to uninstall then restart your computer then reinstall your DVD/CD then reinstall the driver for this device
if your computer came with a motherboard disk the drivers could be on it
click start control panel administrive tools computer management device manager scroll down cd dvdrom drives if you see a yellow question or exclamation mark? ! or a red x right click you will need to update the driver or
select properties general troubleshoot, select driver click to reinstall drivers click update driver

this might be because you have not selected the option to burn an certain type of cd/dvd ie:data ,audio ,iso or your burning software does not support the type of cd/dvd you are trying to burn
there are plenty of free burning software programs on the internet
hope this helps you
which burning software??
