Oxford 911 don't mount

[Emmanuel Di Rossetti]

Hi,

I have an Oxford 911 external drive (200 GB) who don't mount anymore 
neither on my G4 nor on my Powerbook. I tried to fix it with Drive 10 
and DiskWarrior (Disk Utility also) but it doesn't mount either. I 
remember Norton Utilities used to mount unvisible disk in Mac OS 9, Do 
you know if the Mac OS X version is also able to do that ? Or what 
would you be your choice ?

thanks


Emmanuel
