I had written Multi Session Cd`s and had checked them and they were working. I had to format and reinstall Windows. Now when I try to open those CD`s it shows me only the data that was written in the first session. I know the Cd`s are working as I have checked them on my friends computer. I have Sony CRX 220. and Adaptec ASPI installed.DMA is also on . I use Nero 6 Also a very Strange Problem is that after reinstall Windows Xp detects my PIII 550 Processor as "x86 Family 6Model 7 Stepping" which is wierd because earlier it used to show "Pentium III 550 MHz "or something like that. Please help.
