Cannot write or format CD-RWs

I just bought an LG GSA-H42N. It can burn LG’s 8X DVD+Rs, though only at 4X using Nero7. But it cannot write or format my Verbatim 4X-10X CD-RWs using InCD5 under Windows XP, though it can still read from them (as what is reported by InCD). :frowning: However, my dual-boot system’s Windows 98SE using InCD4 had no problem accessing my CD-RWs fully. That is, it can format, read and write the CD-RWs properly. :confused: Where does the problem lies? How to fix this problem? Please help, thanks. :bow:
