Sorry, i'm noob! Never had a array failure! How can i rebuild the array?
October 26, 20196 yr Assuming that the disk itself is good do a quick google search for something like unraid rebuild disabled disk or find it here in the wiki. Keep in mind the things johnnie.black has mentioned about cables, power and the host bus adapter. You should at least try to troubleshoot to find out what went wrong, otherwise you may have the same issue after rebuild. The first thing I'd look for would be whether something has recently been changed inside the case (or if the case was moved to a new location even), this could easily lead to a loose connection. If not, then it's less likely a cable connection and more likely other hardware but still check the connections anyway. Once you dig into it a little bit then the community Devs will have more of a foundation to help you from. Good luck.

I tested every connection, i didn't move server for months, and over a year using sff 8088 cables without issues. Hdd being rebuild, hope everything ok! Many thanks again both!
