I didn`t try to continue.and yes It`s Dell replacement  certified drive. Drive 0:1:3  - was Failed - (20 hours after the alert msg as you said -THEFLASH1932-) I found another Dell sas 600, and push it to cell number 5. The server start to rebuild 0:1:5 by himself. The server finish - (4 hours)  to build 0:1:5 , then the status change to "online". Everything looks fine! I tried to assaing 0:1:4 as a hot-spare again , and now it works ! . It`s look like that  it was too late to try assign disk as a hot-spare....  Impossible  to assign disk as hot-spare when you got physical drive alert\error . Thank You  THEFLASH1932 I really appreciate that.
