OS 10.4 fails to recognize my firewire hard drive

I have a MicroNet 160GB external firewire hard drive that I have split into 2 partitions. One a HFS+ for Mac, and the other NTFS for PC. The plan was/is to use this hard drive as a place to back up files in our lab, where we use both Mac and PC.

Ironically, after partitioning the disk, the HFS+ (Mac) partition would not automatically mount, but the PC partiion does. I wrote a short applescript so others in our lab could double click that and not have to use command-line or Disk utility to mount the drive. Everything worked great until upgrading to 10.4

Now, no matter what I try, the Mac partition will not mount.
My applescript gives me an error that the drive is not mountable.
Disk utility shows multiple partitions, but the Mac one is greyed out, and will not mount. It also gives an error message when I try to verify or repair the disk.

Now here's the kicker, if I plug it into one of our macs that is running 10.3.8, then everything works fine. Applescript, disk utility, everything can mount it and all the data is intact.

It's not a Maxtor drive, so deleting the following files is not an option (cause they're not there)
System/Library/Extensions/IOFireWireMxBt.kext
System/Library/Extensions/MaxtorPowSecDriver.kext

The drive was not connected to the computer during the Tiger upgrade either.

Does anyone have any ideas on how to fix this?

Thanks
