You can't make this cd-rom to autorun, you'll have to backup the data that's on the disk, and then create a new cd-rom containing all the data.
To make it autorun, you'll need an "autorun.inf" in the root of the cd-rom, like explained here:
Autorun.inf, What is it?

what kind of data was the last thing to go on the cd?

Did you make sure that the application you were using was told to write both data and audio?

You used a CD/RW?
You may not have done a multisession. This enables you to carry on from where you last fineshed. If you didn't use multisession, you may have written over your old files.

Hi rkrameshkumar,

The others allready explained what happened, you made a mistake with multisession writing, you used the "create multisession" each time instead of the "continue multisession" option.

Thankfully, nothing has been overwritten in this case, all information is still on the disk, just not readable for the OS.
If you want to recover the data, get yourself a tool like ISObuster (free)

It'll show you the sessions, there just extract the data from the CD.
