As I'm sometimes known to do, I made what I hope is not a fatal mistake. I forgot to disconnect my other HDs while installing XP x64 on my raid array. The result is that it's drive letter is now G:, instead of C: as it should be. This is causing some problems with programs and patches that are apparently hardwired to install in C:. A game patch, that I tried just a bit earlier, apparently thought that it was on C:, which is another OS, and tried to find the game location according to the drive designations in that OS, instead of x64, and found nothing because that drive letter is not used. I can't change it with Windows, and when I once tried doing this with DDS from desktop, I quickly learned that was a bad mistake, because the OS became unbootable. Perhaps the same would be true if booting to DDS and changing it there without the OS actually being operating, but that is the basis of my question...will it work or would it just be another disaster?
