i too had issues but not lost a bit of data - yet - so i am quoting this article related to Intel Storage Manager ... currently removed and readded a member of RAID-5 array and it seems to be rebulding ... slower than eternity "I was using Intel Matrix Storage Console to manage a RAID 5 volume on my "ICH8R/ICH9R/ICH10R/DO/PCH SATA RAID Controller" (at least that's how it reads in Device Manager), and I was running a RAID 5 volume without issue until I experienced a drive failure a couple weeks ago. All three drives are Seagate, and I warranteed the failed drive. After an extended wait I finally have the refurbished drive back from Seagate. I put the drive back into my machine, wired it up as normal, and now the Intel controller utility (when I first start the machine, following a successful POST) shows 2 member drives, and one non-raid member drive. I entered the utility, and it doesn't give me an option to rebuild the array, only to delete it, which would DELETE the volume AND it's data, which, in my mind, defeats the purpose of RAID 5 altogether. Now, we come to the point of the issue. The definition in Intel Storage Matrix Console's help for a "failed" array is as follows: "A RAID 5 volume is reported as 'Failed' when more than one member has failed. If this occurs, please follow the procedure shown below. This procedure deletes the failed RAID 5 volume and creates a new RAID 5 volume; it does not recover the failed RAID 5 volume and its data. After the new RAID 5 volume has been created, you must restore the data from backups and install any software that was on the RAID 5 volume." While I understand the definition, only 1 of my 3 member drives have failed, and honestly, I cannot reasonably afford to lose the data on my array. Intel Storage Matrix Console's help also gives this procedure to recover a degraded array: "In the device pane, right-click on the new non-RAID hard drive and select 'Rebuild to this Hard Drive'." I have no such option. All I have is "Mark as Spare", and "Activate Port LED", since the utility has flagged this as a "FAILED" array. I've attached a screenshot of exactly how my utility appears, and my System Report exported from Intel Matrix Storage Console follows. I really need to find a way to recover my data, please help me!!!

"This really isn't a fix to whats going on with the Intel Matrix software, but here is how I was able to recover the data on my failed RAID 5 array. I had just about given up and was getting ready to wipe the drives when I decided to look at a data recovery app I had purchased some time ago for an accidentally formatted drive. This software (Zero Assumption Recovery) has the ability to also recover data from failed RAID arrays (both RAID 0 and RAID 5). In order to use it, I first had to take the remaining original 3 drives of the array and delete the RAID array that was setup (I did this through the boot time interface as some people have suggested it won't affect the data on the drives). Once you boot back into Windows and start up the ZAR software, it will be able to see the 3 drives that made up the array and after quite a few hours, it will have scanned and should have recovered your data. The trial lets you run the full scan, but only gives you the ability to restore 4 items or folders (can't remember). The software didn't fully reconstruct the folder path that I had on the drive before, but I was able to find all of my files that weren't in the orginial folder as well. Since my array was 3TB, I had used GPT instead of MBR and I'm not sure if this caused the folder structure to not be fully recognized. To avoid this issue in the future, I have built a new server with a dedicated RAID controller (LSI MegaRAID SAS 6260-4i) and 4 2TB drives in a RAID 5 configuration. On my system with the Intel Matrix RAID controller, I switched from a RAID 5 configuration to a RAID 10. I went from 3TB to 2TB in storage, but it should be a bit faster and more reliable since no calcuations are needed for the bit parity. Hopefully this method will work for you guys as well so you can recover any of the data you have lost.
FYI, the link to the ZAR site is http://www.z-a-recovery.com/" -------------------- |

"Thanks very much for reply!
Intel is useless - i did as you told - everithing restored! only difference i have user Diskinternals raid restoration software : http://www.diskinternals.com/raid-recovery/ Looks like intel's raid onboard implementation is crap and should be avoided.. I have never had any issues like this with proper RAID setups (Adaptec etc.)" -------------------- |

"Had a similar problem last month and also a couple of days ago on an ICH8R chipset. Believe the "failed" situation was caused by an intermittent problem with a cd burner while trying to burn a CD, but below is the procedure I used to make the array clean again without recovery software...
When system boots, hit ctl-I to enter the bios utility. A warning screen will pop up at the top of the screen. Don't remember the exact verbage on this screen, but it says in effect that the array failed, do you want to fix it... Answer yes and the array status will change from failed to degraded. (You may have tophysically unplug power for 30 secs or so first to get the controller to totally reset - don't have enough permutations of the problem to be sure of this...) Boot the system, open the Matrix Storage Manager, right click on the drive with the red x, and select "mark as normal" Wait for raid to rebuild. I believe the problem in my situation was caused by a flaky or dying DVD Burner. Historically, I have found that hard errors on a CD or DVD burner will really hang the OS (at least XP) at a very low level in the OS to the point it won't respond to ctl-alt-del and the only solution is red button reset or power. I'm thinking that this low level hang is messing with the low level OS driver software that controls the ICH chipset and the delay is making it think a drive or array went offline and "failed". I replaced the DVD burner two days ago, and will probably take 6-8 weeks to be pretty sure the problem is solved. While your situation might not be caused by the same thing, I believe that any low-level software driver hang in the OS could produce a failed array and this is probably a pitfall of having an OS software driven RAID controller. Would be nice if Intel would confirm this as a possible limitation..." Source : http://communities.intel.com/thread/20495
