I recently build new server/light duty desktop.
Main purpose is only file sharing.Raid configuration :Adaptec 6805 ,8x 3TB HDD WD Red,Intel RES2SV240 expander,Raid 6,set in Intel mobo DZ 77GA-70K.
I upgraded firmwares, but I'm having strange problem.
During Build Verify segment 7 got missing.I just reinsert drive into hot swap bay and it started to rebuild Array. After rebuild was done another segments 0 and 5 gone missing while build/verify. I reinserted drives and now I'm praying that raid is going to rebuild successfully from remaining 6 drives,because I already transfer some data on it(I know it was bad idea).
I checked S.M.A.R.T on missing drives, it only says link failure on all 3 of them and aborted commands on one of them.No Errors on HDDs. Connections and cables are good.
I added 2 fans blowing on RAID controller because it was getting too hot, so I guess overheating shouldn't be issue.
What can be possibly wrong?
