How can I re-partition a 1.8" hard drive, connected to my laptop via a USB enclosure, when I can't get my computer to recognize that it's there at all?

Background: I had an old 20gb Cowon iAudio X5 hard drive-based MP3 player that would act as a USB mass storage device when plugged into a laptop via a specialized dock. You'd turn it on, the player's firmware would load and start running, and a few moments later it would kick into USB storage mode.
By a freak accident that I don't have a good way of explaining, I managed to remove the existing FAT32 partition, but I didn't wipe or reformat the drive. After that, when turning on the player, the screen would just be blank. Without a partition, it couldn't seem to find its firmware and boot up, and therefore couldn't enter USB storage mode, so I couldn't do anything with it.
Now: I opened up the player and removed the Toshiba 20-pin hard drive from the player. I ordered a USB hard drive enclosure and installed the drive. When I plug it into my laptop, the enclosure's green LED lights up and I can hear the platters start spinning inside.
BUT: ...that's all that happens. My computer never recognizes that a USB mass storage device has been plugged in. I've googled for all the help I can get, but nothing seems to work. I have a Macbook with OSX 10.6 on one partition and Windows 7 on the other. The disk doesn't show up in either Disk Utility on OSX, or in Disk Management on Windows 7, so I can't figure out a way to repartition it.
I had a lot of old music and photos that had sentimental value on this hard drive and I'm dying to find some way to recover them without having to pay thousands of dollars for a recovery service, but I'm at my wit's end. The hard drive physically works, and it's connected - does anyone have any idea how I can partition it again?
