I have a a plextor 12 speed CDR drive, an ibm HD and a DVD Drive. I have been trying to put the DVD as a slave on the primary IDE channel with the HD as the primary but it doesnt like it. When everything is connected the HD is not detected i just have the DVD drive as 1st slave and the CDRW as 2nd master. the HD just disappears. When i disconnect the DVD it comes back again. Anyone got any ideas what i can do to get the DVD as a 1st slave?
