Spanned volume versus RAID 0 ?

Q: Spanned volume versus RAID 0 ?

Hey all,

I had a question regarding a spanned volume versus RAID 0.

I understand that RAID 0 uses stripping, and for that reason, if one HDD dies you lose the data of the entire array. However, what I don't understand is why people suggest the same fate if you lose a single drive in a spanned volume setup. Even the Wikipedia page for spanned volumes states that "if any disk fails, the data on the whole volume could be lost." The entire volume? That doesn't sound right to me...

My understanding of a spanned volume is that most files would only be on one drive or the other, and very rarely split. So, if one drive fails, the data loss would be very limited. I always assumed that with a spanned volume, data would just be written to where ever there's free space, so splitting files between multiple drives would only happen when free space is low. Are my assumptions wrong? Do files frequently get split between multiple drives? Or is that just some over exaggerated caution?

Preferred Solution: Spanned volume versus RAID 0 ?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Spanned volume versus RAID 0 ?

That's due directly to the type of RAID setup you have...so for basic RAID setup (2 HDD's) that copies data on to both HDDs, you should use RAID 1. This method will allow you to remove any failed drives and replace with new drive and data will be transferred automatically with no data loss.

Hello all.

I have been researching this to no avail.

Here is the TL DR;

Old computer died which had two 400GB sata drives that houses a lot of family pictures and MP3s. The drives were dynamic and a 745 GB volume spanned across the drives. I now know these drives are also RAID-0, but I wanted to see if I could see any data on them and I had a USB sata dock. Learned the hard lesson that a dynamic disk wont be visible via USB no matter what (at the time I didnt know it was also a RAID-0) . I put the drive (which just happened to be the first drive) in my dock and somehow the drive got corrupted and became a basic disk. Pop up came asking if I wanted to format which of course I didn't. Odd thing is that the partition is intact (745GB) which causes the issue of not allowing me to convert it back to dynamic. It would seem if somehow I could just get it back to dynamic everything would work again or would be a heck of a lot easier to repair.

The issue is I cannot convert directly back to dynamic because it appears I don't have enough "free space" due to the partition reporting a 745GB volume which is correct.

I have tried multiple pieces of software mostly from Acronis, EASEUS, and Runtime (Disk Director, GetDataBack NTFS, Raid Recovery for Windows, and Data Recovery Wizard). Problem is these products don't fully solve the problem and I cannot reliably get the data off. The one product Runtime does have is raid reconstructor - but I am not ready to spend ... Read more

So here's the situation: I have two 320GB disks that were setup as a spanned volume under XP Pro, hanging off a third-party PCI SATA controller. That controller has died. I know in theory, I should be able to replace it in the machine and the volume will still be there. However, this system MAY be totally dead... and putting it all back together will be a pain either way.

Is it possible to recover the volume by plugging both drives into a new machine using USB-SATA docks or external cases?? And if so, HOW?

Hi all,

First I'd like to say that I'm an idiot, I just deleted my spanned volume . I'm about to run the MiniTool Partition Wizard Home Edition v8.1.1 (free version), and just wanted to run this by you guys so I don't mess it up even more. Here's the setup I had that I am trying to recover.

Disk 0 - 1T Spanned volume (F:)
Disk 1 - 64G NTFS System, Boot drive (C:)
Disk 2 - 1T Spanned volume (F:)
Disk 3 - 1T Spanned volume (F:)
Disk 4 - 1T Spanned volume (F:)
... a few others that don't matter
Disk 9 - 2.5 T iSCSI Spanned volume (F:)
So, I was trying to pull the iSCSI Disk 9 off the other spanned volumes on F:. I did a Delete Volume, and they all disappeared. Was I supposed to use Shrink Volume? Anyway, there were a lot of threads about recovering partitions, but none of them I saw had spanned volumes. Is recovering a spanned volume the same as recovering a single partition, multiple times? Or is there something I'm missing?

I am in the MiniTool Partition Wizard, and I see all of the disks that I want to recover. However, it doesn't allow me to select multiple disks. So the only option that I have with this tool is to go through the recovery process on each disk individually. Is this the right method? If so, how do I get the full spanned volume back after each disk is recovered?

Thanks in advance!

A:Spanned Volume Recovery

Just a quick update. I've been scanning the disks for partition data using the MiniTool, and it's come back with some strange results. Disk 0 shows an abnormally large partition. And after a long while of scanning, I haven't found any partitions on the other disks yet.

Even though the first disk is 931.51GB, after finding the partition, the MiniTool is displaying it as a capacity of 6167.3GB (the sum of the entire spanned volume). Does this mean disk 0 holds the partition data for all 5 disks, and recovery of this will undelete the partition on all disks?

Thanks again!

I had three 2TB drive spanned together into a single volume for all my media files. I had the hose on my liquid cooler break and dump all the coolant on one of the drives. It, obviously, is toast.

Now, I would like to get the data of the remaining two.

I have run two different recovery software suites (Easeus and File Scavenger) on them and only find about 1TB of data.

Is there any other way or did I really lose 4 TB of data?



A:Recovering data from a spanned volume

Wow, This was posted a long time ago. I think you may have already solved your problem, but Spanned volumes take the first disk, fill it and moves on to the next disk. For example:
If the 2TB drive that got trashed was the first, well you're ****ed.
If it was second, and no more than the drives capacity was full, you're ok.
If it was 3rd and untouched, you are good to go.
Word of advice: DO NOT FORMAT

I have a spanned volume setup with 4 drives. One of the drives is starting to throw read errors which is preventing WHS from backing it up (Yikes!).

Is it possible to clone the drive with the errors and to reinsert a new drive into the array?

Can the new drive be bigger?


A:Can I clone a drive from a spanned volume?

You may end up cloning the errors as well. An imaging program capable of handling all four drives at once like the Acronis True Image server edition would be able to handle Dynamic volumes if that's what you are working with there.

The best time for any imaging however is while everything is working 100% to make your backup of the entire setup just in case something like this comes up. The imaging program used would back up each block to be restored on the new identical replacement drive in order to work.

I have a system with a spanned volume of five 2TB disks. Actually, the "disks" are all iSCSI targets (since Windows XP won't see targets >2047GB on my QNAP array)... but in any case, Windows shows all the disks as being present and the spanned volume as being "Healthy"... it just doesn't appear to be formatted any longer. The array itself (RAID5 with a hot spare) shows as healthy, and the SMART on all the physical drives shows fine as well. So all the components look to be good, I've just lost the NTFS structure.

Any suggestions on how to recover??

A friend of mine, not me, accidently deleted a spanned volume, One of the disks is an IBM Deskstar 80GB and the other is a Maxtor 200GB with 8M Buffer. The Spanned volume was a total of 190 GB (using unallocated space from both). The volume was deleted using the MMC utility from windows. I was wondering if there is any software out there that would me, not me, my friend, recover the data that was in it.

I have Windows XP installed on a 500 gig drive. I also have a collection of drives that are setup as Spanned Dynamic Volumes through Windows XP.

I want to re-install XP and wonder if the Spanned Volume will survive the reinstall?

I am thinking it would be very wise to disconnect those spanned drives during XP installation, updating, driver installation, then reconnect them, and follow these instructions.

I just bought myself an HDD docking station, and following instructions on lifehacker, tried to create a spanned volume, so that I can use two spare Western Digital 500Gb HDDs as a single 1Tb HDD.

All seemed to go OK until the last point, when I got an error "The operation is not supported by the object"

The two drives are fine, and the dock seems to work fine. I can format the two drives individually, and they show up in File Explorer correctly, but I can't crate a spanned volume.

Anyone any ideas? Thanks

First time posting :blush:,

Situation: I have two hard drives : main drive: Seagate 500GB w/ windows xp and second drive: WD 1TB blank.

Without backing up the main drive (ops...), i went ahead and enabled RAID 0 on both drives and created a RAID volume (128KB strip / Size: 1TB (931.5GB)).
NOTE: the RAID volume size is only showing the exact space of the 1TB, excluding the 500GB drive.
After realizing that I needed to create a backup image of my main drive to use RAID with an existing drive, I'm left with the "Operating System Not Found" message.

Question: If I Delete RAID Volume (which is based on the size from the blank 1TB drive), will both drives become available as non-RAID disks and keep the original data on the 500GB main drive and be able to run windows again?

I'm using software RAID through Intel Matrix Storage Manager option ROM v5.6.2

I understood that "Resetting the drives to Non-Raid" will cause all data on the disk to be lost, so this isn't the approach that I'll be taking til I find a solution to backup my data.
However, from reading the "Delete RAID Volume" option, it listed Deleting a volume will destroy the volume data on the drive(s) and cause any member disks to become available as non-RAID disks, so knowing that the RAID Volume is blank, then maybe trying this will be the answer.

When using the Microsoft Recovery Console in (RAID mode attached w/ both drives) logically there isn't ... Read more

A:RAID issue - deleting RAID volume to restore non-RAID disks

sadly, there's no way to do what you want without an existing backup.

Look at it this way;
A disk has a container ~ the partition.
The partition as a structure ~ the filesystem (eg NTFS, FAT32, RAID).
We put our data into the structure.

When we create backups, we are getting only the data itself (unless you use an image program like Ghost or Acronis where you get all three).

Deleting the RAID will give back the two independent HDs, but also breaks the structure so that the data becomes in accessible.

Lets imagine three situations:
1)You have two hard drives in your PC. Drive A contains Windows installation and other files. Drive B is an empty drive. Your Motherboard supports RAID 1(additionally 0 and 5) and you want to setup hardware RAID 1.
Is it possible to switch HDD to RAID mode, enter RAID BIOS, create array using drive A, copy drive B content to drive A and run RAID 1 using two drives(drive A should rebuild array on next restart and copy mirror drive A on drive B)

2)You have two drives, drive A and drive B running in hardware RAID 1.
You need to format drive B, copy drive A's content oto drive B(which should be non-raid drive now) and install non-raid drive B on another PC.

3)You have three drive A, B, C.
Drive C contains Windows and other files. You need to setup RAID 1 using drive A and B and then copy Windows from drive C to newly created array consisting of drive A and B.

All three scenarios require no Windows re-installation.

Can anyone please post step by step tutorial for all three scenarios or point to already posted appropriate tutorials?

A:Covert single disk to RAID and vice versus

Good luck with any of those scenarios. That isn't meant as a flame but more as a reality check. Some (expensive) dedicated RAID cards will rebuild an array etc but most motherboard onboard RAID setups will make you start from scratch if a drive fails. I'm no expert but my advice to you is to backup, make an image, before you try to do what you proposed.

1) I create a restore point when my boot unit is designated as Basic (unit/partition).

2) I modify the boot unit to be Dynamic for subsequent mirroring- RAID 1 purposes.

3) I 'fall back' using the restore point in step 1 above.

After the 'fall back', will the boot unit be Basic, or Dynamic? Is the mirror lost if I've created one?


A:RAID 1 Boot Unit Versus Restore Points

Hello Lairbear,

A restore point is only for system files, and would have no affect on the hard drive and how it's file system is formatted or partitioned.

You would not want to convert a drive that contains your Windows installation to dynamic. If you do, you will make Windows unbootable. Windows can only boot from a basic disk.

Hope this helps,

Hi Guys..one of my computers is down..the OS is XP sp 3 and it is using RAID...this morning when booting up it said a windows system config file was corrupt and to do a recovery to the system...I attempted to that but everytime I got to the R for recovery the system said the "Drive could not be found" i.e. no hard drive...My thinking is that the main Drive is bad..It is an Hitachi drive..I would like to take advantage of the fact that I have a second drive that is suppose to mirror this drive...I was going to replace the Hitachi with the Mirror drive and make that the main one and then I realized that I would have to turn off the RAID function as I now will only have one good drive (I am assuming the mirror drive is good)..Is my thinking correct.?

My hard drives are a 128GB SSD boot drive, and an HDD data drive. Recently I upgraded my data drive from a single 1TB drive to a 3 disk RAID 5. There was no issues in changing to RAID from AHCI, and no issues assigning drives to the LD.

Windows 7 boots and is stable as long as I'm not writing to the RAID volume. I can read off it fine, and can write to it for a random amount of time prior to getting a BSOD.

Using BlueScreenView I get a check string of DRIVER_IRQL_NOT_LESS_OR_EQUAL and a code of 0x000000d1. The processes in the stack for each crash were ahci64s.sys and ntoskrnl.exe. I'm not sure where you can find what each parameter actually is telling you, so I can't provide much amplifying information there. I couldn't gather anything from the events that occurred around it.

Any help on this would be appreciated. Even if you just let me know where I can find the meaning for each parameter in the dump file, that'd be greatly appreciated.

Hello Guys.

My latest Computer which I built about 4 weeks ago is playing up.

It is the first time I have used Sata drives and my first RAID setup. My chipset is 945P, I have two WD 3.0 250gb Hard drives set up as RAID 0. I have Wndows with SP2.

Anyway here's what it is doing. Most times I start it up it will not boot, I get a black screen asking me to select proper boot drive. I have tried loads of different 'boot orders' but it is still unpredictable so I will keep trying by turning it off and on and it will boot eventually. The thing is, Sometimes when the computer is on and I am doing something it will crash and go to that same screen.

The other problem I have is I am getting an alert from my task bar that says an Error has occurred in my RAID volume and I should backup immediately. If I click on the icon it will take me to the "intel matrix storage console" where it will state that my volume on Port 1 has an error.

What I'd like to know is if the two problems I am having are related and if the 'error' on Port 1 is a physical error within that HD or I can just format and start again.

Any help is appreciated and I am happy to answer any questions.

I have a RAID5 array. The PC started acting up, forcing me to run it in Safe Mode. In Safe Mode I transferred files onto an external HD and put them on a working computer. Now I want to fix the old PC with the RAID5 array.

Before I transferred the files onto the external HD, I thought I could save myself the trouble and expense of going to a store to buy one by simply taking one of the RAID drives out and installing it in a working computer. But that didn't work. The new PC wouldn't read the drive. So I put the RAID drive back in the RAID PC. Now it says 'Degraded'. I don't know if that means I killed the drive, or maybe it was 'degraded' before, or if I re-installed it wrong, or maybe it's fine but there's something I'm supposed to do.

RAID 0 means striping. Both disks must be fine otherwise you lost everything!!
Both are detected... what do you mean... BIOS sees them?
Only one in raid volume.... maybe you mean something else but both are needed. Only one isn't possible.

I then left-click on disk management which provides a graphic on the right side of the screen of the unallocated RAID volume. Right-clicking on the unallocated graphic provides the choice of: ?New Simple Volume?, ?New Spanned Volume?, ?New Striped Volume?, ?New Mirrored Volume?, ?Properties?, and ?Help?. Note: ?Change drive letter and path? is NOT available as an option.
From there, I?m not sure how to proceed. The graphical representation of the unallocated volume is the RAID Array. I don?t want to create another RAID 1 Volume.

But then it says the disk is unallocated and wants me to create a new dynamic volume, i say simple volume.
But now is asking to format... and here i stopped, with out formating to new ntfs.

Is there a way to recuperate / restore / reinstate / recover / rescue / rebuild .... the old dynamic ntfs simple volume ?
So that i could access the data without having to use a data recuperation program for 3TB of data.

Will a quick ntfs format and a scan-disk make that possible?

Hello MasBlaMan,

I think it is a big mistake to use any RAID for storage without having backups I also think that as you have started to make changes in windows that it may well be too late to save your files, but I may be wrong. Formatting it would only make matters worse so I would not do that.
You could try booting a live linux cd and see if it is possible to retrieve your data that way, but you would need somewhere to put it ie an external drive.

This is on a machine with Windows 2000 server SP4 and I'm using FAT32. Is there a work around in Windows or do I need to format it using FDISK which I normally use for single HD's. If I do need to use FDISK, how do I access the raid from it? I have searched on this topic and is was suggested I have the raid cards driver on the boot disk. Not a problem to add that, just curious as to how I need to go about doing this from the boot disk.

Hi there,   i recently upgraded my Hp laptop by a 128GB m.2 SSD. first i removed my old HDD(1TB) & i installed my OS(w8.1) to the new m.2 SSD. it was running super fast. but as soon as i inserted the old HDD with the SSD,  it fails to boot. it say "boot device not found". i think there's a AHCI sata port issue on my laptop bios & i can't access it. Is there any way to access it ? i think my old 5400RPM HDD is the first boot device anyhow. but i want the new SSD as my first HDD.Sincerely,Me

This system has an Intel DQ35JO mobo with two WD 320 GB hard drives configured in a RAID 1 array. When the system was brougt to us, it was infected with malware. My technician connected each of the hard drives to another computer to begin the malware removal process. He used SuperAntiSpyware and Malwarebytes to remove what they could find. When the hard drives were installed back in the computer, he got a boot error "C:\windows\system32\hal.dll-missing or corrupt", and the system would not boot. I disconnected the drive on Port 1 and the system booted successfully to the drive on Port 0. The Intel Matrix Control Manager saw the RAID array as degraded of course. I turned off the computer, reconnected the non-booting drive to Port 1 and rebooted; the computer booted sucessfully and Matrix Control Manager began rebuilding the array. Why did the computer give the hal.dll missing message and not boot, instead of booting automatically to the drive with the good OS on it? I have limited experience wth RAID arrays, but is that not the purpose of a RAID 1 array?

Just received a new hp computer I ordered with two raid drives. It gives instructions on how to create a volume, but unfortunately, they already created the raid drives as 0. How do I change volume from 0 to 1 as I want to run mirrored drives. Any suggestions? Drives are Intel.

I have enabled RAID in the BIOS, and have 2 drives connected. I do not see any options and nothing happens when I press CTRL-I during boot. I've done this many times on a PowerEdge and it prompts you to enter RAID bios during POST.
Why don't I have option to configure? I called support and they were scratching their heads too. It may be worth noting that WIndows 8 is installed and secure boot is enabled.

I came to this site while googling and likes the solution provided at this site. i will very grateful is someone can help me.

I have os (Vista) installed on one hard drive and i have a raid 1 array containing two volumes. I had everything going fine but then one day my friend by mistake went into disk management and formatted one of the raid volume. Since then i am having problem even booting up my computer.

When i disconnect my raid array by unplugging data cords behind the hard disk, i get BSOD saying that i have video car driver failure. I took my od disk out and ran chkdsk on it by connect it to an external hard drive enclosure it went fine.

When i connect the formatted raid 1 volume to enternal hard see all 465.8 GB of free space. But when i connect my unformatted raid 1 volume i get CRC error. when i do chkdsk on it, i get error saying its a RAW file format which is not supported by chkdsk.

Please suggest.

I have a 4-disc enclosure set up as a single RAID volume, attached to a desktop running Windows 7 Professional, 64-bit.

About every 2 or 3 weeks, I must reindex this volume, because it simply stops working. I don't know if it is getting corrupt or just disappearing, but the windows search on this volume clearly doesn't reference an index any longer. I can rebuild the index, and the search works, using the index again.

I have googled quite a bit and found many people discussing Windows 7 indexing and some problems associated with it, including the thread here about rebuilding. I have yet to find anyone who seems to suffer the "losing index" problem that I am describing.

Any guidance on this will be appreciated.

A:Windows 7 keeps losing index of RAID volume

I've been researching more and I found a Vista user that says his index was lost after running defrags.

In Windows 7, does defrag run when the PC is idle? If yes, can this be turned off?

edit: I just reread the Vista users comments, and apparently he was using a 3rd party app called "MyDefrag". But still, my question above stand. I am wondering if defragging the RAID volume can cause the index to be lost.

I am having trouble installing windows 7 (home premium) on my new raid array (2x intel 330 120GB SSD in RAID0)

Basically, windows CAN see the raid volume. it recognizes that there is a single 223 GB volume available. I select "Load Driver" for the volume, and plug in my trusty USB with the appropriate intel SATA RAID drivers. Win7 recognizes that there is a compatible driver on the USB, installs it, but still says:

"Windows cannot be installed to this disk. This computers hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu"

The format and create new partition options are grayed out for this volume.

So what did I do to get here?

Using the Intel Rapid Storage Technology tool, I combined the two drives into a raid0 volume. This is confirmed because when I restart, the raid volume shows up in the RST echo with the right size, and also indicates that the volume is bootable. It is also confirmed because the windows 7 setup only sees one 223GB disk.

I have confirmed that in the BIOS, the SATA controller is set to RAID mode (not AHCI).

I have confirmed that in the BIOS, the first boot option is "RAID intel SSD"
Ive tried the RAID drivers that came with the motherboard, Ive also tried the raid drivers available from intel and the latest raid drivers available from the motherboard MFR.

What else can I do?
Thanks in advance for any help.

My XP desktop had a BSOD. After the reboot the Intel RAID manager saids "Failed RAID volume detected. Recover volume? (Y/N):"

I don't want to choose yes if it will wipe all my data off both drives. I'm running a RAID1 and both drive states are "Error Occurred(0)"

If I recover the volume will it just repair the array and keep all the data or just wipe everything and make me start over? I searched for this problem but can't find a definite answer.

A:Safe to recover failed RAID volume?

Not sure if anyone can give a definitive answer on that
It's 50/50
Hence the reason to always have backups created
Raid1 (or any raid really) is not good when trying to recover data (ie nearly impossible)
Therefore, when you're brave enough press Yes :suspiciou

Hey all,
I have been beating myself up over this file sharing thing. Brief explanation of the system setups. I have a work computer that serves as a camera surveillance server with a third party program. All is fine with that, in fact never better. The cameras use the #1 NIC for the data for the surveillance program to record it and all that jazz. The time has come for more storage, so I made a NAS server of sorts with a raid controller card 8 x 2TB hard drives in RAID 5. Again all is well with that setup.

Incoming problem

On the camera server computer, lets call that comp. A, the #1 NIC is lan connection 1 setup as Work Network. #2 NIC is connected to the NAS server via a crossover cable. Both computers are part of the same work group called CAMERASERVER WORKGROUP. When they are both connected, the second network connection comes up as Unidentified Network (Public Network). This is not a big deal to me since from computer A I can see computer B in the network and can access the Public shared folder on computer B. But I am trying to share the raid volume designated disk E: at 12.7TB. When I right click the volume E: and select share with, I can create a share folder named NAS archive. Then on computer A I can see that shared folder, but when I try to double click into it like I do on the Public share folder I get a permissions error.

Says something to the effect of "You do not have permission to access \\xxxxxx. Talk with your network administrator to... you know ... Read more

Can Bitlocker be used to encrypt mirrored disks in a RAID 1 volume?

If so, What happens when one drive fails?
Will I be able to read the other drive?

On another note, would I be able to take that 2nd drive from this computer and put it into another computer and get the files? (assuming I have the password)

Thanks for any help on this issue.

I hope you can help me, I have this very frustrating problem that I can't seem to solve in that when I put the computer to sleep and then try and restart it it goes into a loop situation where it tries to start up (power light comes on, fans start), then about a second later fails and goes back to sleep (power button goes off, fans stop). It will do this continually until I pull the power cord, neither the power or reset buttons affect the behavior.

This is a desktop PC built with the Gigabyte GA-EG45M-UD2H board http://www.gigabyte-usa.com/Products/Mo ... uctID=3021 and using Intel RAID 1 on two Seagate ES.2 drives, no additional cards, 2GB kingston memory (1 module).

Vista Ultimate x64 installed on the RAID 1 volume.

Intel ICH10R, latest Matrix Storage manager, latest Mobo BIOS etc.

This also happens in Win 7 RC 64-bit but am now stuck on what to troubleshoot next.

Any help you could provide would be greatly appreciated. Thanks!

I just recently did a Windows 7 re install so I would have a clean slate when using a new raid setup. (LSI 9211-8i with (4) 2 TB WD Red) I am new to RAID's but everything seams to be working fine. I used 4, 2 TB WD Reds in a RAID 10 and got the expected 3.7 TB of space. I run my OS on a small 120 GB SSD and put all my user accounts on a different drive as shown here.

User Profiles - Create and Move During Windows 7 Installation

So to get back to the problem at hand, when I went to create a new simple volume initially to do this it would only allow me to put 2048 GB in a volume. Not a big deal because I though that I would be able to set up a new simple with the rest of it later. The problem that I'm wondering about is that now that it is all set up and running I can use the rest of the space. When I am in disk management and right click on the unallocated space everything is grayed out except for Properties and Help.

I'm not sure what to do about this . Although I don't need the s[ace right now I don't like the idea of 1.5 TB sitting there unusable. If I'm going to do something about this I would rather do it now than later.

Hi Everyone,

I have a DKT-702 Computer (OEM brand, from Harris Technology in Australia). I have identified that it uses a Foxconn H67M-V motherboard, which utilizes the Intel H67 chipset. I would now like to add a RAID1+0 array (utilizing 4 x 1 Terabyte Drives) to my computer, however I need to keep my primary hard drive (a Samsung EVO 840 - 250 Gig SSD).

The motherboard manual clearly indicates that the motherboard does support the RAID type that I intend on implementing. I have a little bit of experience with RAID on personal computers, so I plan to go about the task as follows -

1). Disconnect the primary (SSD) drive
2). Connect the 4 x 1T Disks
3). Enter the BIOS and set the "IDE Mode" to RAID
4). Enter the RAID Utility & setup the RAID volume
5). Partition the new RAID volume as I see fit (it will only be for data, no OS).
6). Plug the primary (SSD) drive back in
7). Start the computer up
8). Install the Intel Matrix RAID drivers into Windows (7)
9). Reboot

Given the following intended procedure is there anything that I should be particularly careful about? Alternatively if anybody can suggest a better procedure I am very open to adapting my plan. My primary goal is to keep my primary drive safe from data loss, and to implement a new RAID1+0 array purely for the storage of data.

Any advice will be greatly appreciated.

Kind Regards,
