I don't know... it seems quite unstable. at first the partitions show up in "my computers" for a couple times after several reboot, now its gone for ever. Windows do recognize "mass storage drive" though, they just don't assign a driver letter to it I guess. While I open "computer management" and "logical discs" and try to do this manually, it doesnt show any harddrive except the system drive (virtual hdd) any ideas wots going on? Win2000 SP4 with all patches and updates thanks.
