access to Readynas admin page impossible, one disk looks dead

Thanks StephenB 

Vincefr34I would not advise to try this on your own. Logs don't contain everything and I am conjecturing that you just need a fix to the sdc (disk 1) partition table but it is important to point out that one should examine md-superblocks and look at the md-logs to determine/confirm that this is the correct action to take. Doing this incorrectly or taking the wrong action can cause even more issues. Letting Netgear Level 3 support assess the situation, is the best at this point.
