I was getting delayed write errors every time I started Windows Pro XP1. I have visited many online resources to recitfy this issue. Anyway, I had shut off write caching to the HD and modified the system registry...etc....with no success. I started to take out the CD-R drive from the computer so that I could make a boot CD and try a system recovery when I found another CD lodged in between the CD-ROM casing and the computer casing itself. I removed this CD and put the computer back together. Now when I boot up I am no longer getting any delayed write failures. I have seen that device drivers and USB can cause this as well as hard drive errors and incompatibility issues, but does anyone know if this CD could have actually caused this error?? I am beside myself trying to figure out how it could have possibly caused this....Any ideas???
