the disk is a WD external USB/Firewire/eSATA disk sized 1GB.
Formatted as HFS+ I use it on my PowerPC Mac, but sometimes connect it to a windows XP machine which reads HFs+ via MacDrive. Windows crashed with the disc attached and since then the WDs does not mount (Linx, PC, Mac).
I still hope that all the data is there, but somehow the partition map/superblock/driver (?) is gone.
After start on my Mac testdisks shows:

Select a media (use Arrow keys, then press Enter):

I do not know how to proceed from here. Maybe someone can help me with this.
Question: Shouldn't there be a driver after partition1? On my built-in discs there is one and there is plenty of free space in part. #2.
Any help appreciated. Thank you in advance!
