I couldn't find an external docking setup for this SAS disk, seems like we need an actual controller in order to interface with it. Mike Pedraza in Downs had such a unit, so I took the disk over to him, but he wasn't able to interface with it in any way that allows us to get the data out. He wants to try switching out the logic board, for which we need an identical disk. We have only one such spare at the 40m that I could locate, but it is not clear to me whether this has any important data on it or not. It has "hda RTLinux" written on its front panel with a sharpie. Mike thinks we can back this up to another disk before trying anything, but he is going to try locating a spare in Downs first. If he is unsuccessful, I will take the spare from the 40m to him tomorrow, first to be backed up, and then for swapping out the logic board.

Chatting with Jamie and Koji, it looks like the options we have are:

  1. Get the data from the old disk, copy it to a working one, and try and revert the original FB machine to its last working state. This assumes we can somehow transfer all the data from the old disk to a working one.
  2. Prepare a fresh boot disk, load the old FB daqd code (which is backed up on Chiara) onto it, and try and get that working. But Jamie isn't very optimistic of this working, because of possible conflicts between the code and any current OS we would install.
  3. Get FB1 working. Jamie is looking into this right now.

Seems like the connector on this particular disk is of the SAS variety (and not SATA). I'll ask Steve to order a SAS to USB cable. In the meantime I'm going to see if the people at Downs have something we can borrow.
