Your computer is an older pentium 4 PC. As such it uses ATA / IDE - EIDE drives. These days stores sell SATA drives but IDE drives are still VERY COMMON. You can find tons of them on eBay or your local computer store (for much more than eBay). The original drive has a 24x CD reader, 8x CD-r writer and a 4x DVD reader. It does not write DVDs. You can buy any ATA/IDE drive you like and now you can probably afford a DVD burner too.

can you give me the name of the driver and i'll get you a site to download it

its 3rd time again its giving me problem

if your disk is worn you have to buy a new one from sony with the original software on it. there is no other option

There could be several things which are causing your CD burner not to act in the way it should.

I had a similar type problem after installing Windows XP, .Service Pack 3 onto my Sony VAIO model VGN-SZ330P.
The standard Windows burner kept saying there was no CD in the drive but it would play both CDs and DVDs.

I went looking for an alternative and now use IMGBURN which is a free lightweight CD / DVD / HD DVD / Blu-ray burning application . You can find it at http://www.imgburn.com/.

I also installed CDBurnerXP which is another free application to burn CDs and DVDs, including Blu-Ray and HD-DVDs. It also includes the feature to burn and create ISOs, as well as a multilanguage interface. You can find it at http://cdburnerxp.se/en/home

The above does not tell you why your burner is having problems (and they could be numerous), it will certainly get the burner doing everything you need.

you need a DVD burner in it to play and Burn DVD's
you have a CD Rom in it now.

I found a link that might refer to your situation, I don't know what OS you have but see if this will help.
