https://community.hpe.com/t5/proliant-servers-netservers/strange-behavior-of-disk-array-controller/m-p/1118458#M17825 My server has following configuration:<BR /> totally 6 disks, 5 disks in RAID 5 (two logical disks for OS and data) and one disk in RAID 0 (only for data).<BR /> Recently this server has been crashed. After analyze, I found 1 hdd in RAID 5 has been failed (it was replaced) and disk in RAID 0 has status "Preductive failure" (also has been replaced). The OS also crashed.<BR /> On RAID 5 I can see only one logical drive (4GB with OS). Other logical drive with size 260 GB doesn't have partition (corrupted).<BR /> I've installed latest firware on RAID controller and all HDDs.<BR /> Now every time after restart I see message of RAID 5 status "recovering". After 34% it's stops and status changed to "ready for recovery". Status of all HDDs now is green (normal).<BR /> Also when I use some utility to recover damaged partition and data (Get NTFS Data Back), it works till 34%, then I have I/O error. But I can see partition under this software.<BR /> Could you explain me, what it the problem of RAID controller? Could you recommend some software to recover NTFS partition itself?<BR /> <BR /> Thank you.

The difference in spare part number, firware version, RPM.
