In my case I use the Intel with a raid5 and i have to start windows to rebuild the raid. It can not rebuilded from the Intel Matrix Storage Manager BIOS. The problem is, while rebuilding the raid, i have a lot of BSODs. What i have learned is, You shouldnt install window on a raid, without having a seperate OS on a seperate HD in the computer for repairing. Or you know for sure, that your raid bios is capable repairing a damaged RAID by his own. <br />PS: Sorry for my bad english.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1585105787473796476.post-41819267670008048002013-03-12T20:52:01.247+00:002013-03-12T20:52:01.247+00:00It scares me to make a recommendation, but I think...It scares me to make a recommendation, but I think the wiped drive will be the mirror, not the original. an image backup of the c drive would be highly recommended.<br /><br />of course the biggest mistake would be picking drive 2 as the master..... huge fan of an image backup before any raid work.<br /><br />on my own system, new motherboard surpriseingly does not support raid.

Everything was going OK - even though during the years of use (more than 4 years...I'm thinking of an upgrade anyway) there were some instances were I had to restart the system (freezing) and noticed in the right side the icon with the Array rebuilding (checked with the Intel Matrix sw).<br />Yesterday though, my system not only froze but it made some annoying repetitive sound (not HDD click) and had to hard reboot. However after having to step out right after that, came back in a few minutes and noticed a black screen with two options - F1 to go into BIOS and see what's wrong (something like that) or F2 and load the default BIOS. By mistake (I realize now) I choose F2. All the BIOS settings were as from the factory - and because (another fault of mine) not writing down all the changes...didn't remember exactly what to change - so left it like that. Of course, the PC didn't boot (insert a CD/DVD bootable) - got back to BIOS, noticed the boot sequence, changed to 1st - the HDD. The SATA configuration though noticed was on IDE (the default).<br />After that - the PC booted, Win XP started recognizing a new HDD...and now I have two HDDs (C: and E:) instead of "one" (C:\). Both are working (tried a few random files from both and everything was OK). Tried to run the Intel Matrix SW - didn't show anything - mentioning not being initialized.<br />I would like to have the RAID back. The question is what are the steps and the risk?<br />Thanks in advance<br />SorinAnonymoushttps://www.blogger.com/profile/13348664137313861379noreply@blogger.comtag:blogger.com,1999:blog-1585105787473796476.post-71561301672916923772012-12-30T05:31:52.769+00:002012-12-30T05:31:52.769+00:00Aloha Tim - Problem solved!!

I downloaded AMD's RAIDXpert management program from the AMD website and proceeded to use it to rebuild each of the two separate RAID arrays. I tested the program on my Backup drive first and when that went without incident I ran it again to rebuild my primary drive. It took just over 3 hours to rebuild the 500GB main drive and everything seems to be back to normal and 100%!

From your separately-sent-email, I saw more details - Disk Manager did report a Duplicate Disk-ID/conflict: The disk is offline because it has a signature collision with another disk that is online<br /><br />This does look like a problem with the disk-ID -- I was not even aware this was a changeable-thing. I don't know the answer to your question, but I would surmise the following. <br /><br />Your suggestion of changing the disk-id seems reasonable, but you might try this idea first. Normally you can match the drive's disk-ID, as seen in the RAID software or in DiskManager, with a printed label. In your case, I would:<br /><br />1. Shut down the computer and match the ID with the printed labels<br /> <br />2. Locate the (good) drive, the one with the same printed label as the two identical drives. <br /> <br />3. Then, remove the offending, mismatched drive, leaving the good drive. <br /><br />4. Reboot and confirm the operating system boots. <br /><br />(If the boot fails, simply swap the two drives and boot from the other. If this does not work, I would be confused.)<br /><br />5. Once booted, consider backing up you data in case something goes wrong.<br /><br />6. Then, destroy the mirror-raid (e.g. discontinue the RAID (however you do that on your AMD board)). Hopefully, this can all be done in hardware/bios (I hope you are not using a Software Mirror).<br /><br />7. Re-attach the (bad) drive and rebuild the RAID, as-if-new.<br /><br />If the drive-ID still conflicts, do your rename step.<br /><br />Write back with what you find.<br /><br />traywolfhttps://www.blogger.com/profile/06205565591880314520noreply@blogger.comtag:blogger.com,1999:blog-1585105787473796476.post-20773256201023798332012-12-25T22:37:56.946+00:002012-12-25T22:37:56.946+00:00Aloha Tim: I'm sitting here on Christmas Day ...Aloha Tim: I'm sitting here on Christmas Day readin articles on Rebuilding a RAID 1 array as I have discovered a problem in one of my 2 500GB drives with it's uniqueID that caused it to go offline sometime ago. I found an article describing the ease of using 'diskpart' to fix the uniqueID of the offline drive but now wondering if I will safely be able to change the ID, reboot and have the RAID rebuild on its own? I do not have the Intel software tool you refer to as I am running an AMD Quad Core on a Gigabyte board. I don't know if any real RAID control program unless it is something included with my Win 7 - 64bit OS? Any input on if it would be safe to proceed by renaming the uniqueID and rebooting to see what happens. The challenge is I do not have a valid backup image and no extra drive or space large enough to create one.

Software raid is a very dangerous creature, subject to all kinds of failures. By having RAID in hardware, software can be totally corrupted and the RAID will survive. (Remember, RAID is not meant to keep software problems from happening -- if you delete your OS, it will happen on both disks....)<br /><br />With Intel, the Windows RAID component is only needed to conveniently monitor the RAID. With out the software, the hardware RAID will still function normally.traywolfhttps://www.blogger.com/profile/06205565591880314520noreply@blogger.comtag:blogger.com,1999:blog-1585105787473796476.post-13329191901749949762010-11-19T11:19:15.092+00:002010-11-19T11:19:15.092+00:00All I can say is SHAME on INTEL for now allowing a...All I can say is SHAME on INTEL for now allowing a mirrored disk to be created from the BIOS CONSOLE when creating a RAID array from a non-raid state.

When I restarted the system, it took about 20 minutes to load, and then, unfortunately, crashed taking the remaining drive down as well.<br /><br />Then I found out the recovery application couldn't access the backup files, so I had to rebuild from scratch. Fortunately I was able to recover some of my data from the 2 raid drives after the system was restored, and I had previously backed up critical data files so it wasn't a total loss.<br /><br />Suffice it to say I'm done with RAID. I'll handle my own backups from here on in - at least I know what I'm dealing with there. <br /><br />Anyway, thanks again for your help and for maintaining this blog.Canajunhttps://www.blogger.com/profile/17529505799866207528noreply@blogger.comtag:blogger.com,1999:blog-1585105787473796476.post-44015463167584815912010-11-08T13:08:27.322+00:002010-11-08T13:08:27.322+00:00Tim - Thanks for your response.

On my computer, fixing the Hard Disk Cache, as described above, did wonders for improving my speed. <br /><br />But I believe others, even after making this change, still see slow speeds. It is possible you have an actual bad drive. <br /><br />To completely dissolve the Raid, confirm you have a good full-disk-image backup. Then in BIOS, disable the RAID feature, then remove the (failed) drive. The existing drive should work as-before. Remember, with hardware raid, there is nothing on the physical media that tells it is on a RAID.<br /><br />I still wonder if you actually have a bad drive?<br /><br />Please reply with your actions and what you find.traywolfhttps://www.blogger.com/profile/06205565591880314520noreply@blogger.comtag:blogger.com,1999:blog-1585105787473796476.post-86574366732273501972010-11-08T01:47:36.311+00:002010-11-08T01:47:36.311+00:00I too had a Raid 1 Degraded message.

I would think 450 is large enough. If you had a high-end video card, then I would begin to suspect the power supply.<br /><br />The trouble with my recommendation is this: It is expensive to test, unless you happen to have a spare power supply laying around. <br /><br />By chance is the PC connected to a battery-UPS? My prior experience showed each time I printed on the Laser, the RAID would fail. While this was not a Powersupply problem, it definately was a power issue. If I were to move the printer to another circuit, all would be well. <br /><br />I've seen vacuum cleaners also trigger power problems.traywolfhttps://www.blogger.com/profile/06205565591880314520noreply@blogger.comtag:blogger.com,1999:blog-1585105787473796476.post-21696740811797815502010-11-01T07:42:21.935+00:002010-11-01T07:42:21.935+00:00Hi,

At first I was just researching if I should use a separate RAID card rather than the onboard Intel RAID but now I think I will try out with a new power supply. Problem is, my current power supply is actually 450W and I am only running 2 x 1TB WD HDD in RAID 1, an i7 Quad Core x980 CPU, an entry-level graphics card and 3x2GB RAM.

If the powersupply is larger, it may be weak. <br /><br />Unfortunately, this is hard to test without actually trying a new powersupply.<br /><br />I say this especially because the drives are randomly failing -- it can't be the drives are malfunctioning. <br /><br />In all of my experiences, RAIDS failing like this are always power-related.traywolfhttps://www.blogger.com/profile/06205565591880314520noreply@blogger.comtag:blogger.com,1999:blog-1585105787473796476.post-15691001588094149542010-10-18T14:37:42.721+01:002010-10-18T14:37:42.721+01:00Hi, I am having a similar problem with a Dell Pre...Hi, I am having a similar problem with a Dell Precision workstation running Win7-64bit (on a UPS!).

This is a good reason to pull the disk and do my one suggestion where you boot the machine without the disk; destroy the raid, then re-insert the disk. <br /><br />When you destroy the raid, your data will survive on the good disk (remember, the RAID is happening at the hardware layer and there are no data changes on the disk). The only worry here is to be sure you pull the bad disk. The RAID screens will show you the serial numbers of the disks.<br /><br />If it fails after this, abandon that disk. <br /><br />The backup is just for safety -- data is always worth more than hardware.<br /><br />I wish I had more precise steps; I've done these before, but did not document the exact steps.

If you insert a new drive, you will need to manually select the option to rebuild that drive.<br /><br />Well I was hopeful that if I shut down, let the computer sit for a few minutes, and turn it back on, it would resume at 25%...unfortunately not, it started rebuilding back at 0%.<br /><br />Question - If I need to rebuild the RAID, will I have to use the backup to restore the data? In other words, if I deleted the faulty drive within the RAID bios and tried to recreate the RAID, would I lose all my data?<br /><br />Thanks again for your help. Hopefully I'll have this resolved soon.<br /><br />DaveDavehttp://www.nextexitstores.comnoreply@blogger.comtag:blogger.com,1999:blog-1585105787473796476.post-76809697498166913132010-06-30T05:54:05.171+01:002010-06-30T05:54:05.171+01:00Reply to Dave: 9hrs seems very long.

I'd let it run and check on it in the morning; what would be the harm?<br /><br />If it fails again, try the following: Boot the machine normally (and don't bother to rebuild or cancel if you can). Make a backup of your drive.<br /><br />Then electronically remove the failed drive from the raid (exact steps -- I can't recall), re-attach and rebuild. <br /><br />If that fails, I've done this: <br />Power off and Physically remove the disk.<br />Boot the computer (with only the good drive)<br />Open the RAID control panel and remove the failed drive, essentially turning the system into a non-raid.<br />Boot again to make sure everything works properly.<br /><br />Then, re-insert the "failed" drive and rebuild the RAID using my "software" instructions. Obviously, when removing and re-installing disks, power off the computer at appropriate times.<br /><br />I wish I had the exact steps documented for this and this is worthy of a second article, using a test machine. In any case, I doubt the drive really failed; these disks are very reliable. <br /><br />Write back with your results.traywolfhttps://www.blogger.com/profile/06205565591880314520noreply@blogger.com
