My Passport SE after Lion upgrade: error

Hi to everybody

i have a very simple network of two mac computer . On one of the mac’s i have connected the My passport SE via USB and i was using the time machine program on both macs to backup the files. This till the upgrade to lion.

Now time machine works perfectly with the machine where the My passport is USB connected, while it is NOT working from the remote mac: it mounts the hard disk, (finds the HD) , prepares to backup and… that is it: error shown.

Any idea how to solve this issue??

Thanks in advance for all the help.

I think the problem is that Lion is not yet compatible with all the WD products. They are workiing on it.
