CD Burning Issue

Hi Folks.

Two Machines exactly the same problem.

One Sony Viao Laptop. One HP DX2420 Desktop PC Brand New.

When we burn a CD-R x52 Disc with some photos using Windows XP’s built in software we cannot view the disc unless the computer is restarted. When you view the disc after the burn you only see the amount of free space but nothing showing for used space and it shows no files. You can take the disc out and put it in the other machine and it reads fine. If you restart the computer it reads fine also.

This has happened in the last few days. Both were fine before.

Any Ideas…
