I had a GA EX58 ud5 motherboard and had 2 raids on this system. Raid0 of 2 SSDs and Raid5 of 4 Samsung 1TB hard disks. Everything was made at bios&boot matrix storage controller (you know the Ctrl-I and make setup before windows load). Windows was working fine and speeds were as they should at file transfers. Never installed the windows part of intel storage management..
Motherboard died, so i bought a new one, however i didn't want to spend a lot of money because a possible upgrade is near in 5-6 months (3rd gen i7s). The new motherboard is DFI Lanparty JR X58 T3H6 and was chosen because it could handle my ram setup and had the same ICH10R controller at low price, i thought!
I started the motherboard, prepared the bios settings for raid, shut down, connected the 2 and 4 hard disks of my two raids and started the pc. SSD raid was showing fine but! the 4 samsung hard disks were having a "incompatible" on their lines and there was not raid 5 samsung, showing anywhere. I just couldn't do anything about it from the menus of boot-raid options (8.5.0 version ). In windows (i didn't format, they load fine, for now..) i could see as "not initialized" the samsung raid but i couldn't initialize it, was getting error of can't find target. I didn't expect to see it in windows,i thought that whatever doesn't show in boot/dos messages will not show in windows but anyway. I decided to make a final effort and installed the intel rapid storage technology 10.6.0.1002.
The SSD raid showed fine and also showed the samsung raid 5 array..but as failed.
After reading many discussions in these pages here i decided to risk it and press the "reset to normal" for the failed raid5. I was certain all hard disks were fine 1 day ago, i was certain the problem was just on the controller side and it's bios part. After some few minutes, about 5% of rebuilt, i was able to see and run the contents of the raid, i left it for 4 hours and the rebuild was done.
Everything seems fine.
The questions are. Is this thing stable? Should i return the motherboard and buy a new one?
The "incompatible" of the boot raid controller menus makes me nervous. How can the controller from the bios/boot side say that he cant handle the samsung raid and at windows (software side?) the raid works perfectly? Hmm it doesn't, the array is "write protected". Can't find a way to undo this ..protection...i guess i must backup immediately, release drives from raid, and try again.
Update 1. I opened Disk Management of windows, samsung raid showed as read only, i put the samsung raid to offline , then i switched it to online and problem seems solved..
Still, i am gonna run away from this raid5 asap! Raid10 seems more reliable...
