Hi everyone, this is what I did to take TM on Lion 10.7.2 working with my MBWE1 2Tb:
1.- Update MBWE1 auto and then manually to last version, .12, and then reboot. I think this is not necessary, but i was in “test mode”. I guess that with one on them will be OK.
2.- Change password (by the GUI on MBWE1) to user WD_Backup from backup to backup, yes, the same password.
3.- Deactivate mionet, ftp service, itunes service.
DHCP, AFP, alerts (by mail-gmail), Twonky media server and ntp service are activated.
4.- In lion, finder, connect to serve (cmd+k) afp://(ip of MBWE1)/ When ask for user, login with user:“WD_Backup” and pass:“backup”, all without “” of course… IT IS IMPORTANT TO USE THIS USER: WD_BACKUP, no other!!!
5.- Open TimeMachine and now you must your MBWE1, if don’t you need to run this command in terminal to say to TM uses net HD:
defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
6.- Select your MBWE1 in TM and copy will begin.
That’s worked for me, if don’t for you, I’m sorry…
