Hard Drive Light Steady On

This morning after a quick power outage my Antsle started up and the hard drive light is remaining steady on. I cant connect via .us, how do I troubleshoot and fix this?

Thanks

Jeff

Update: I managed to get the antsle server back up after plugging in a monitor and keyboard then booting up and accessing the bios, then saved and exited without making any changes. Now I see one of my antlets are missing, I am thinking somehow this was the issue and it's being ignored now or deleted? If so how do I find out and how do I access the HDD partition where the data created by this antlet was being saved?

Thanks

Jeff
