I have a hard drive that won’t allow any other IDE devices to be detected in windows. All devices are found in the BIOS but once in windows the HD is there (C) but the other two devices (D & E, CD-ROM Drives) are not there. I take the C out and put into another machine on the Secondary port as Master or Slave, same thing the drive is gone. This drive C is found in BIOS but not windows. I put a different HD into first machine and it works fine and the ROM drives are located in windows as well. I have no idea what would be causing this. Any insight would be appreciated.
