I have pretty well given up on using a Mac with my Drobo at this point. I want to get my latest time machine backup off the Drobo so I can recover some files. I installed SL on an external disk ( a partition) and booted from that. Unfortunately I had upgraded the FS to the latest firmware and the Drobo FS was flakey with the TM partition and it would have taken years to get things off that. Using smb worked fine to the other shares.
Anyway, can this be done from a shell? To say I am discouraged with all of this is an understatement
