Hi - new to forum here, but I just went through this exercise with a WD 320 and wanted to add a couple of things that I didn't see in others' experiences with the upgrade.
I'm using the WD 320 IDE Scorpio something or other. Physical swap wasn't too difficult, though I must say, the build quality and QA of this device has a lot of room for improvement. One of the screws holding down the disk drive bracket was screwed in at an angle at the factory, so it's crooked and almost pokes through the plastic post. Also, one of the power wires (from the battery terminals to the logic board) was pinched by a chassis screw post, breaking through the insulation, so bare wire is exposed (I fixed it with some electric tape). Not wanting to buy a roll of Kapton tape, I carefully pulled the original stuff off the factory drive and applied it to the new one.
After cussing at the plastic bits that wanted to keep falling off the sides of the unit as I put it back together, I fired it up and plugged it into my Mac Pro. Launched Disk Utility, saw the drive and tried to partition it. No MS-DOS or FAT32 choice provided. Quick Google scan and I found the command line below:
newfs_msdos -v focus1 -F 32 /dev/rdiskN
Note, the source I gleaned this from used an upper case -V, which is incorrect. It must be a lower-case v. The focus1 volume name was just something I made up. And, the N in /dev/rdiskN is the disk number for the device you want to format. You'll want to make sure you're executing the command on the right disk. In Disk Utility, you can right-click on the icon of the disk and get more information.
So, after rebooting the FS and connecting it to my Mac again, I see the device mounted as a MS-DOS FAT32 drive in a single just-under-300GB partition (don't recall the exact number). But, after several reboots and even a system reset (which resets the clock, among other things), "Please wait" never went away. My Mac could see the disk, but the FS apparently couldn't.
I resorted to using the FS format utility (even after reading that it breaks up the single partition), but after saying it completed the format, the FS still didn't see the disk (please wait, still). When I plugged it into my Mac, the partition that I created with newfs was gone. So, I re-executed newfs from a terminal window.
I could see a FAT32 partition in Disk Utility once again. But this time, before I unplugged the FS from the Mac, I ran the erase utility. I recalled that the erase utility lets you choose a file system type, and seeing as MS-DOS wasn't an option before, I wanted to check and see if MS-DOS would be offered now. Sure enough it was.
So, I used the same volume name (focus1) and erased the disk with MS-DOS format. Oddly, under physical disk icon, I saw disk 1 and FOCUS1 listed as partitions. I unplugged the unit and rebooted it. Yay! 356 minutes showing. But, when I plug the FS back into the Mac, I only see the one FOCUS1 partition/volume in Disk Utility. Not sure where "disk1" went. I'm assuming it was a temporary representation of slice 1 (disk2s1) that is now FOCUS1.
I'm now going to test it out, but I thought I'd share what worked for me while it was still fresh in my mind. Hope this helps someone that might be running into the same issues I did.
