I recently obtained a dual 867 G4 MDD with two additional hard drives (one on the front and one on the rear carrier). The one on the rear has a capacity of 186 GB while the one on the front has a capacity of 168 GB. The rear drive will always appear after the machine is turned on, but the drive on the front will occasionally appear. I have tried disconnecting and reconnecting the cables, but the problem still persists. I have noticed that the drive on the rear is an ATA drive and the drive on the front is an IDE drive, don't know a whole lot about the types of drives and any help would be greatly appreciated. Also, I've had some difficulty with Target mode with this computer in either direction to my Ti G4 500 MHz. It appears that either HD is not recognized when in Target mode.... any ideas? Thanks.
