Lots of bad things are going on with 8.9 try 8.8 or 9.5 (not out yet be works good).
The error you get on RAID 0 that degrades RAID 5 has been know to happen and is sometimes fixed with a BIOS update that should only cause a verifying and repair of the array such like a improper shutdown.
Of course if you have setup a Matrix with RAID 0 and 5 across all the drives then thats the same as problems in 8.9
Yes, both setups are across all drives.
I installed the unofficial 9,5 a few minutes ago and it seems to rebuild a lot faster then the 8.x.
I'll test if any more fake errors occur after the rebuild completes.
Unfortunately, there's no option to cancel a rebuild in 9.5 either.
Confirmative. I have the same problem too. Only RAID 0 and Raid 1 across all disks. The system hangs for a long while, then reports an error on RAID 0 and starts rebuilding the RAID 1 after marking the failed volume as normal. My first thought was that something wrong with the disks. I switched to disks from another vendor and for a long time everythinf was fine. I was almost sure that this was a real disk problem then. And yesterday it happened again. So, it is definitely not disk related, either Intel RAID controller or some other hardware or software component causes the problem.
I doubt that the Matrix Storage Manager is responsible. It is just a passive shell, as far as I understand. More likely it is something related to the RAID controller firmware or correspondent windows driver.
I haven't tested if enableing cache on the RAID 0 (although useless from a performance p.o.v.) reduces to rate of the occurance.
You mean cache on write? I have this option on.
I just installed Intel Rapid storage 9.5. We'll see how it will behave.
Yes, write cache.
If it's on for you and there's no difference...then it means it doesn't help.
