Hi all Iyonix PCers, My confidence that all 4 drives worked was premature. :-(( After putting the case back on, Nixiyo wouldn't show the second hard drive icon on the iconbar. (Why do things always go wrong only after you have put the case back on?) If I then do a reset all drive icons are present. This is not very satisfactory. To remind readers the configuration is IDE bus 0 (primary) IDE bus 1 (secondary) Master Slave Master Slave Main Hard Drive Second HD DVDRW CDRW Main Hard Drive = the one Nixiyo boots from. OK, so I have to try another configuration. Since the main hard drive has to be on the primary bus as master, this gives 3! = 6 possible arrangements. I don't fancy going through all 5 of the other arrangements and so can folk advise me which arrangement(s) are likely to work best? For what it's worth, the details of the drives are: The main HD and the CDRW are the original ones fitted by Castle, the second HD is a Maxtor Diamond Plus 9 80GB ATA/133 and the DVDRW is a LITEON SOHW-1693S23C. The arrangement I was going to do, but was put off from doing because of the physical difficulty of fitting the cables in, is as follows. IDE bus 0 (primary) IDE bus 1 (secondary) Master Slave Master Slave Main Hard Drive DVDRW Second HD CDRW Any comments?
