Fun's not over yet. i got my working RAID on the third try with a few persistent problems...

- First off, I have had to type "sudo chmod a+rw /mnt/md0" in order to access the RAID. Is there some way to make this command sticky?

- Second, there is the continuing problem of md0 showing up as a folder and not viewable as a disk which is a problem with at least one of the Other Users who knows just enough to select what they want from the menu that appears when they click the HDD icon. When I created the Mark One RAID (the one I forgot to wait until the striping was completed before plowing ahead with the mount and save) I opened the RAID in GParted, gave it a name using my personal disk naming conventions, and that resulted in an icon appearing on my desktop and the RAID appearing in the HDD list in the file manager under the created name. How possible is it to do that again?

- And now, the one I can't get any handle on -- I started copying files from various HDD sources on to the RAID when power went out in the LDK portion of the house (LDK and bedrooms are on separate lines. Running the aircon, work PC, this eight-disk PC, TV, and oven was more than the circuit breakers could take and darkness ensued as soon as I set the oven to preheat. When I logged back into the machine, the RAID directory was completely blank. Even Lost and Found has disappeared. Gaining RW access again had no effect on seeing a menu. I have the originals of the files I copied, so that is not a part of this narrative.

Running "cat /proc/mdstat" and "sudo mdadm -D /dev/mdo" delivers entirely normal results. I have resisted trying to re-mount and re-save the active array or rewrite the RAID to intramfs. After two days of reading I can't tell whether it is best to do the create and attach over again or do something else for which I am not finding a suitable command that will allow me to search for the missing files. Is there also some way of preventing file directory losess such as this?
