Recovery of an image into a RAID system
Can someone please help me? I have an ASUS P5K-E motherboard with an Intel ICH8R Southbridge RAID Controller. When I bought the computer the RAID with two discs was working perfectly, but disappeared after a BIOS update and became an IDE system consisting of 2 discs where the OS (Windows 7) is booting from only 1 disc. So I tried to re-establish the RAID with the following idea: Image from the actual disc, make a new RAID and bring back the whole OS including my data by booting with Acronis and recovery. But after I boot with Acronis I cannot see the RAID system..?

Thank you shadowsports!
Well I couldn’t do it: Switch on the (Intel) Raid and boot the computer normal gives me a blue screen for like less than a second (too short that I can read something). Boot again and Windows tries to repair it itself, but couldn’t fix the issue either. So my question as you say that the JMicron is a completely hardware based RAID controller: How can switch on the JMicron controller instead of the Intel? Bios Revision 1035
Thank you for your help!

Hi Martin,
You cannot indscriminately switch between the two RAID controllers. Each controller uses different drivers and these need to match what the system is expecting in order to start. One of these is already on your disk. You need to know which was in use in order to make the correct BIOS settings. The method you use to restore or rebuild the RAID will be determined by this.
With Windows 7, it is possible to disable automtic restart on a system failure or STOP error (BSOD). Example STOP:0x0000007b "Inaccessible Boot Device". This is a selectable menu option by pressing F8 (after POST, but before windows starts to load). Note: there is only a small window (about 5 sec) when this option can be selected during the boot process.
It might also be possible for the system to repair itself using the windows 7 DVD. Select the Repair option and perform a start up repair.
You had stated your system was booting, but now it won't? Or it won't if the SATA Configuration option in BIOS it is set to RAID. Keep in mind, that if this setting is used, both disks need to be "marked" as included in that Controller's RAID Configuration Utility. As long as the disk "marked" as the "source" in the RAID Config Utility has a valid copy of windows installed, you should be able to start the system in this configuration. The second disk will be marked in the Config Utility as a "mirror" It is possible to start a system from the source disk, even if the relationship between the disks (RAID1) is broken. This is only possible for this RAID level (this controller, this situation) because when RAID 1 is used, each disk contains a complete image of the OS or data. In RAID 0 (for example) data is interleaved in chunks (oftern referred to as "stripe" size) between two or more disks. None of the disks contain a complete image of the OS and therefore if any of the drives fail, or become corrupt, the array cannot function. A little off topic, sorry.
Once you have the answers to these questions, you can decide how to proceed.
Do you know which controller your disks are connected to?
Is the controller set to operate as SATA?
Is the controller's operate mode set to RAID?
Do the disks appear in that controller's RAID Config Utility?
By default, windows vista and 7, disable any storage controller drivers which are not in use. Restarting the machine with incorrect BIOS settings in PATA mode instead of RAID might cause a problem. Here is the solution.
In anticipation of your reply, can you tell us what kind of back-up or image you have of your system? Full System Back Up Image, Image of the System with a Broken Array, etc?

Well first of all the RAID disappread a while ago and since I have a problem to install the Intel Raid system (not a true hardware based RAID controller as you said) I would like to try out the JMicron Controller (if that is a true hardware based RAID Controller I shouldn't need a driver, should I?), but how?
Yes I set the controller to SATA (but how can I change between Intel and JMicron?) and yes the mode is now RAID. The regular blue screen appears, but unlike before I cannot switch back to IDE mode. So now I'm happy that I amde an image of it! And Yes the disks appear in the Intel (Ctrl I) Config Utility without problem and last but not least I have a Full System Back Up Image.
Thank you for your help!

Hi Martin,
As I mentioned earlier, now is not the time to to be making changes to the configuration. Have you tried going back to what worked previously? I suggest you stick with the original configuration, or what was working. It seems you are using the Intel RAID. However, the system won't start now and you are not sure why.
The more serious problem seems to be a result of your attempt to create a new array. This is nomally destructive, so your OS might be gone? I am not able to gleen this information from this exchange. You should be able to see the error or reason why windows cannot start if you disable the automatic restart as suggested.
Each change you make can introduce another variable or potential problem which might keep you from achieving your goal.
A RAID1 image can be restored to a single drive, as long as you:
a. change the Configure SATA option from PATA to SATA in BIOS
b. Change the controller's operate mode to RAID
c. Configure Intel RAID in the Boot Order Options
d. Ensure both disks are members of the RAID set in the Intel RAID Config Utility, and most importantly, the disk you restore to is marked as the souce RAID member.
These changes need to be set after an image is restored, before the system is restarted and windows attempts to load. Ideally, you want to restore the image to a functioning RAID set, but you have indicated that the boot environment does not see your members as a single disk. The RAID Configuration Utility lists the disks available for inclusion by serial number, port and size, so you can assure which member disk you are restoring to. If your image is not of the working system in a RAID configuration, these steps do not apply.
