Yes. I've tried that to no avail. It seems to just sit there with the progress bar not moving for 20min every time I try to use Disk Utility. I even tried using Disk Utility on a powerbook G4 to fix this issue, and using Mac Drive to reformat, which apparently was successful, but the drive is still not recognized when I get to the install screen. However, I can repartition or reformat any other ATA based drives either Parallel or Serial.

I can use any other disk reformatting/partitioning software (i.e. acronis or paragon) to create other partition types, but can't seem to put the HFS+ on this drive (though it worked once). I'll keep playing with it and let you know if I get it working. In the mean time is there a work-around for the IOKitWait?
