Hi Guys, Hoping someone can help me. I built a custom DS box using DS3612xs DSM 4.2 build 3202 which was running fine until last night. I had restarted the box but it would come up to the new configuration / install screen on a different IP Address. After another restart the custom box was able to start up properly though some options were missing the DS was coming up with a status of good. I noticed an error stating "Config Lost". After another restart the custom box is not booting anymore and I suspecting if my boot key is corrupted. If it is corrupted can I build a new one and be able to reuse my RAID 5 volume or will it wipe the drives? I have about 1tb of data on it that I need to recover. Any help would be appreciated. Kind Regards, Michael
