Did you update the firmware during your process? What you are describing has happened to a lot of people and it was the result of a firmware update going bad. After the update, the ssh and http server daemons do not start when the machine is booted and therefore leaves it useless.
If this is the case, the only way that I know of to get your unit working again is a complete factory restore. If you have data on the drives that you need to recover, I suggest you use my howto tutorial to try and get the data. Once the data is safely retrieved you will need to reformat the unit. I achieved this by reformatting all of the drives on my temporary linux machine then plugging them back into the ShareSpace. Once you start up with blank drives the unit rebuilds itself completely and then all should be back to normal.
