I have two identical Western Digital drives set up as slaves. Both are set up identical,(jumper settings etc). The machine is running Windows 98. When i remove one of the slaves and replace it with the other, BIOS recognises it but Windows does not. Control panel/system/device manager says that the primary IDE controller is not setup correctly. I have tried removing it and rebooting to no avail. Any ideas why windows wont recognise the identical drive.
