You *could* try to restore the partition table by dd-ing a matching one from http://www.rockbox.org/wiki/IpodConversionToFAT32 to the disk. However, this can also permanently loose all data, so I would recommend doing this on a raw copy of the complete disk. If you're familiar with Linux you can do this without much work. You could also try to figure the first sector of the data partition of the Ipod and dump from that point into a file, then mount it on Linux. If the filesystem is still readable you should be able to get your data back. If the filesystem itself is corrupted you could try tools like testdisk and various commercial data recovery tools.

Hello Jscap,

I hope you can solve your problem. As bluebrother said try some recovery tools. For transferring your music back to your computer I can suggest you a freeware program called sharepod. If you have rescued your files, then it is not such a problem if you really have to format you player,.

Good luck.

Greetings,

You can easily create a backup copy of the old partition table before writing a new one.   Then you can easily undo by writing the backup you created.  For example, create the backup using
--- Code: ---dd if=<iPod disk device> of=ipod_mbr_backup bs=512 count=1
--- End code ---

The only danger is writing to the wrong place, or writing the wrong thing and overwriting other data.  Ensure that the text "<iPod disk device>" is replaced with the correct device path, such as "/dev/sdb".  If you write to the wrong drive, you can lose access to data on other drives and even cause your computer to not boot. 

Testdisk is great for undeleting partitions.  If the FAT32 partition is still there, Testdisk can find it and write the proper entry into the partition table.

Jscap:
Well I did find something earlier called zero assumption recovery, would this work?

torne:
It's probably nothing to do with the partition table; Windows detects filesystem type by looking for the BPB/superblock/whatever inside the partition, it mostly doesn't care about the types in the MBR. Complaining that it's RAW usually just means the first sector of the partition has gotten destroyed somehow and no longer looks like a FAT BPB.
