Okay, I haven't been able to figure out what's going on with my IDE drives or how to fix them. I currently run an AMD Athlon 64 3200+ on a ASUS A8N5X Motherboard. I installed OS X through an iDeneb 10.5.6 release with the Voodoo 9.5 kernel. I installed it on an IDE hard drive inside of a USB enclosure. My problem is that I cannot read/write/mount my two internal (Western Digital) IDE drives. The first one is set to Master, second set to Slave. I selected the nforce chipset drivers during install, but still no luck. I also tried several kexts from the InsanelyMac website including the AppleNForceATA.kext and the AppleOnBoardPCATA.kext . I used KextHelper to install the Kexts, still no luck. After I installed the kexts i rebooted with "-f -v" and I received a few errors. Some were from AppleIntelATA, but they flew by the screen too fast. However, I paid more attention to some from AppleNForceATA. It said it found 0 units and then gave a message saying, "phy connection failed 0x0000000". Apple system preferences detects both drives, but when I try to mount through Disk Utility it shows the disks, but does not show the partitions on the disks. My IDE cd drive works fine in OS X, but the hard drives don't. I haven't tried entering any device IDs as of yet into the kexts. Any help would be much appreciated.

What kind of partitions are on those disk.
How about removing one of the internal drive. Leave one drive in there and set it as master.
Also check the ide cable, if the IDEs are Ultra-ATA, use the cable that looks dense. There are several types of IDE cable, the one that looks dense is the kind you want to use
