Q: Solved: RAID boot issues - disappearing disk - RAID question

Yesterday I woke up to find my computer had bluescreened overnight. scsiport.sys was in the bsod message, and the stop error code was 7a.


(Click to consult the online MSDN article.)
A page of kernel data was not found in the pagefile and could not be read into memory. This might be due to incompatible disk or controller drivers, firmware, or hardware.

The system has preformed fairly flawlessly up to this, save for a CPU fan error which I may have caused in testing (note to self: never detach a system fan while the computer is running JUST to see if the fan readout/warning system works....) and bluescreens a while back because I had both DVD drives set to cable select.

I rebooted several times and the system did not find a bootable drive - it would just hang at the cursor that displays before the XP splash screen appears. Once, my raid utility reported my RAID 0 failed. I have two Seagate 320GB 7200RPM drives in RAID 0 and a 500 as a standalone drive I use for backup. My board is an ASUS M2V

XP Pro SP3

The 320GB drives are in SATA ports 1 & 2, and the 500GB is in the port labeled as RAID 1 (there are only 3 available SATA ports). The 640GB array is partitioned into a 100GB windows parition, and a 460GB storage partition with some unallocated space on the disk.

Finally, it booted to windows and I began to verify my data had been backed up, which was not the case. (I use NovaBackup as an automated solution.) So, I began to manually backup and the BSOD appeared again. I rebooted and it once again hung on the cursor before the XP splash. Rebooted several times and it finally went back to windows... same BSOD after about 3-5 minutes. Rebooted several times, no go.

I booted to a live ubuntu CD and received error: ata1: port failed to respond along with a slew of other errors. I rebooted and it went to linux - no hard disks were found.

I disconnected the disk drives, booted, shutdown, reconnected and booted again - same error. Reseated RAM (whynot) - same error.

Long story short - after no less than 30 reboots, XP finally booted stably and I backed up my data. The system has not had the same issue since, yet I would not be surprised if it happens again.

However, Last time I booted, the 500GB disk had disappeared. It was not in My Computer or Disk Manager. Rebooted, and it was available.

I am just looking for some information and advise on this issue. My diagnosis is a failing raid controller on the board, or a failing disk. I've listened closely to the drives, and there is no audible sign of failure. Perhaps I'm using the RAID1 SATA port incorrectly.

I'm looking for a disk utility to verify the integrity of the disks.


Also, I have a question about drives in RAID 0 -- if I were to detach my RAID 0 drives, insert new drives, and change the raid configuration.... would it be possible to reinstall the old drives, change the raid config back to RAID 0, and boot from the drives, or would the RAID need to be rebuilt/reformatted. I've wanted to try that just as a test, but haven't had the time if it fails.

Thanks guys - much appreciated!

Hello All

I have 2 500Gb SATA Seagate disks in a Raid 0 (stripe) configuration running VISTA. Was running like this for a while and then installed another 250Gb SATA Seagate drive.

My raid controller recognized this disk as a non-raid disk and I could see it was using port 2 on my raid controller (port 0 and 1 were being used by the 500Gb disks). I then preceeded to install XP on the non-raid disk (had to use F6 to install raid software while doing this install). Xp installed fine and I can access the RAID-0 disk while in XP. The problem is I cannot boot into VISTA again.

I tried playing with BOOT.ini but cant get it to recognise the RAID-0 disk as bootable. Please help!

hello everyone,

I am thinking to renew the whole data in current raid1 array md0. My environment is:

raiddev /dev/md0
raid-level 1
persistent-superblock 0
chunk-size 16
nr-raid-disks 2
nr-spare-disks 0
device /dev/hdb1
raid-disk 0
device /dev/hdd1
raid-disk 1

this '/dev/md0' is /home, so I'm not booting from this disk and the other file systems including root and /boot are on /dev/hda.

What I want to do is to renew the whole data in /home.

Is there any way to do this by switching /dev/hdd1 with all new data copied, then sync this new data to the other raid disk (/dev/hdb1) : FROM /dev/hdd1 (the disk just added with new data) TO /dev/hdb1 (currently active raid disk)??

Usually, after switching the HDD to new one, data in /dev/hdb1 is to be copied to /dev/hdd1 for recovery. But in my case, I want to do the opposite.

I would be so appreciated by all your helps,
Thank you,

A:RAID question: how can I renew the data in raid array?

I'm not sure what you want to do.. You want to copy something to the /dev/hdd disk (from another computer maybe) and then copy the data from /dev/hdd to the RAID array?

Since you are using RAID1 then it should be fairly simple.
You just simulate disk failure by removing /dev/hdd. You could do this by making the hdd drive hdc instead (jumper it to be the secondary master). Now you mount the "hdc" drive (that really was you hdd) and copy whatever you want to /dev/md0.
Since it's a RAID1 array then all the data that goes to md0 is written to hdb and when the /dev/hdd comes back the RAID is syned onto both disks again.

I'm not sure if that makes any sense to you. Can't be less obscure than your post though

Before I post the rest of my info, here is exactly what happened leading up to this...

My computer froze and I restarted the computer. It ran for a few more minutes and then it froze again.

Then the as it was restarting the cooling fan failed.

I restarted the computer and it tried to load a few more times but would not completely load the OS and would freeze.

Then each other time of restarting it had trouble recognizing my DVD-R/RW drive and HDD.

I checked the BIOS and trying disable then enable the RAID function in the BIOS. Also changing the Boot order to DVD-R/RW first then HDD then switching it back to no luck.

I double checked the connection to the DVD-R/RW drive and HDD.

My computer has a diagnostic function, so at start up, I ran the diagnostics and my processor and 8 GB of ram is running correctly.

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.

OK, I was using one Vertex 120 as my Windows 7 C: drive and bought another to take advantage of RAID0 performance. Did a system image backup of the C: drive to my 1TB D: drive, installed the 2nd Vertex 120 (both are FW 1.5), enabled RAID in BIOS and created a RAID0 in the Intel RAID launch program. Then did an image restore to the new RAID0 C: drive. And... it won't boot -- hangs about 1 second into the "fireflies" in the boot process. It must be the boot.ini doesn't like the RAID0 config when it was backed up as a AHCI drive. Windows 7 repair fails. How do I gain access to the boot.ini file? Or is it the boot.ini file?

I should add that it does boot from a clean Win7 install, just not the image restore from the single AHCI Vertex.


A:Cannot boot from non-RAID image restored to RAID SSD

You need to get the raid drivers into the o/s you just restored.

The only way I can think of to do that is with Paragon Adaptive restore - select P2P adjust o/s ,select the o/s to adjust, select upload drivers, browse to the .inf - give it a few secs to load , next, Apply, and it's done.

I am confused, hope you can help - I have 2 2TB disk drives configured as RAID 0. This is confirmed in Intel RST. RST says 3815 GB total size, roughly 4 TB available, which is what I would expect as RAID 0 supposedly makes available the sum of the drives in the array as its size.

But File Explorer in Windows 10 Pro confuses me - it basically says 2 TB is the size. I might assume it is just wrong, but the "used" space is around 1/2 TB, which is what I believe the actual size used really is.

I have 3 questions:

1) Is this just an error in File Explorer on the space reported?
2) How much space do I have left? File Explorer says 1.5 TB, I would hope it is 3.5 TB.
3) Is there a utility or way I can get an accurate report of space truly used, free and total if File Explorer is unable to handle RAID 0 arrays?

Hi, this is my first post in Windows seven Forums.

I am building a laptop for college with two identical drives, and unfortunately no on-board raid controller. They are 2 120gb ssd's and I feel like they would be alot more useful as one drive rather than 2 small drives. I have Windows 7 professional x64

After doing a ton of research, I believe it is impossible to boot Windows 7 from a software striped array, correct? The only thing I have found to combat this is "Native VHD Support". Unfortunately I don't understand VHD at all. Is this exactly what I am looking for?

My only other option (as far as I know) is to install windows 7 onto as small a partition as possible on one of the drives, and then stripe the rest of that drive with the other drive. The only real problem I have with this is I have used a computer with a small drive and a storage drive before, and it is very annoying, 1 drive is much simpler. Is it possible to move many important (and large) windows files onto a secondary drive (the striped array in my case) and "convince" windows that the "D:" drive is the OS drive? essentially have everything naturally install to, be on, and run from the "D:" drive?

Better yet is it in any way possible to run a small program pre-windows boot that will software raid the 2 drives? Or can Windows set up the software raid, and then boot from said raid array?

Basically I have 2 drives, no hardware raid controller, and I don'... Read more

My mum recently gave her computer to me since she got a netbook and thought that she wasn't getting enough use out of such a computer. An error message kept showing up when I powered on the computer, apparently this had been showing up for some time.
It was on the Intel Matrix Storage Manager before Windows started, one of the physical disks were listed in red. However, the computer was still in full working order, but I wanted to get rid of the screen that kept coming up, so in an attempt to fix it, I went into the Matrix Storage Manager's configuration utility and not knowing what it would do, reset the disk listed in red to Non-Raid.

Now ever since I've done that, I've seen nothing except the BIOS, all that comes up after the Matrix Storage Utility now is a device listing and it says at the bottom 'DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER'. I inserted an OS disk and nothing would come up. Since then, the closest thing I've had to progress was by going into the BIOS settings and changing the hard disks SATA mode to 'IDE'.
After setting it to that, the Matrix Storage Utility doesn't show up, which I thought was a good sign at first, but then afterwards the same final screen shows up, but the message at the bottom had changed.

I have two 500Gb SATA drives in a RAID 0 config set as my system drive 'C', and a 1TB SATA as a storage drive 'E'

Never had this problem until last night when I removed the storage drive. Tried the usual fixes with no luck, put the drive back in and the system boots normally.

The problem seems to be that I installed Windows on the RAID array while the storage drive was attached, and for some reason Windows decided to make 'E' the active partition.

Have attached a screenshot.

'E' also shows as System for some reason, even tho Windows is on 'C'.

What I want to know is can I fix this problem without reformatting/reinstalling, and what will potentially happen if I make the 'C' partition active? Dont really want to kill my machine right now!

All comments and advice appreicated.

No problem. First, mark the Windows partition as active.

Then, run a startup repair.

A:Dual boot with Raid + non-Raid

Hello hines57, welcome to Seven Forums!

The method in the info below would be the best way to go about it; just be sure to reconnect the SATA cables for the RAID into the original port.


The easiest way to do away with boot issues between separate Operating Systems (OS) is to use the BIOS one time boot menu to select which OS to boot at system startup, each motherboard has an individual hot-key to tap during system start-up to access this menu.

If you have 2 separate Hard Disk Drives (HDD) and have one OS installed to one HDD and you want to install another OS to the second HDD, disconnect the HDD with the first OS installed on it and leave only the HDD you want to install the second OS to connected.

Just be sure not to change where the original HDD SATA cable was connected, it has to be re-connected to the exact same port to avoid boot issues.

Install the second OS to the connected HDD and when complete and the system is booting good, power down and reconnect the first HDD with the first OS on it.

This way the OSs will boot independently of each other and there will be no boot conflicts between the 2 separate OSs to have to sort later.

Then set the BIOS to boot the HDD / OS you want as default and if you want to start the other (new) OS you use the BIOS one-time boot menu to select that HDD / OS to start when the PC is started.

I have a Lacie Ethernet Disk 2TB and it was working fine for 9 months now. I have assigned a dedicated IP Address, as I have done to any computer on the network. But since yesterday, when I try to turn it ON, the System Status LED keeps blinking green and never stops. So I cannot connect, either ping or anything.

Problem History:
Yesterday I tried to enter through the Web-Manager but I could not: I was landing on page home_mainF.cgi but it was a blank page. I tried to see the Lacie Storageserver from the Storage System Console and though it found the LacieServer, on the System Information it was displaying Version 0.0 (as if no firmware or anything was installed).
During all this time, I could access all folders and files on this server with no problem. I just couldn't access the web-manager.

I read the troubleshooting section of the manual, and it said that if you cannot access the web-manager you should turn off the system and try again. So, I shut down the system (using the power button). After that I cannot turn it on again. The Power LED is OK (solid green), the HDD LEDS are solid green, but The System Status LED (second from the right) is blinking GREEN all the time. Nothing else is on or blinking.

So, now, I cannot have access to it. Pinging is not working and the system console cannot find it.

I would really appreciate any help.

Thank you in advance,

(Using XP Pro)

2ata 1TB NTFS > Partition Type: HPFS\NTFS (0x07)

I'm trying to install Vista 64 on a D975XBX2 mobo.

I've updated the BIOS, got the latest 64-bit RAID drivers, uploaded everything, set it up in BIOS, etc.

Everything looks fine in the bios - it says two of my drives are linked in a RAID 1.

I install Vista - load in my raid drivers, etc. First boot, everthing still looks good.

I've got everthing installed - OS, apps, desktop. Great. I do a reboot.

Now, BIOS said there's no RAID. I check the Computer/Disk Manager icon and it tells me I've now got a 2nd drive (unformatted) What was the 2nd RAID drive is now out of synch
with drive C.

Any idea what might be going on?

I have previously tried RAID 1 and found it to be too encumbering, was thinking about going RAID 5, but the extra disc space seemed a little too much (plus if one HDD were to go down I wouldn't be able to hot swap it for another). So I'm back to RAID 0. What I want to know is how reliable is it? I'm not too worried about being able to swap a dead drive, but I would like speed.

Another thing. (This is a probably a dumb question but..) If I have data on one drive already (ie: OS, apps and games) I would need to back my data up if I didn't want to have to reinstall and the RAID was set-up, right?

RAID 1 is new to me but my computer with 2 -500 GB drives is going to be switched from RAID 0 to RAID 1 because one of the two drives failed and I lost everything. Here's the question:
I have read that typically this conversion if done by system software, but "hardware implementation" is strongly recommended instead. Specifically, what is required, a second (separate controller?) or what? What is meant by hardware implementation?. All answers appreciated.

A:Solved: RAID 1 question

"hardware implementation" basicly; means using a separate pci raid controller card as opposed to the motherboard option.
In my opinion RAID 1 is not really much use to the home user, its really designed for the office server where downtime is an issue.
The only redundancy RAID 1 has is mechanical failure, if one drive fails the other one can be up and running in minutes.
There is no redundancy against software corruption or virus attacks as both drives will be infected.
Remember RAID of any flavour is not BACKUP

Hi Guys
Just installed my first Raid O array.
I installed two 200g sata 2 hard drives, when installing windows I created a 40g partition. Drive C is showing 40g and drive F is showing 380g.
What I would like to know is should drive F be showing this amount as I thought using Raid O I would only see a total amout of 200G.
Not sure if I have installed it correctly.

I want to setup a RAID 0 array. I have a Western Digital 160GB SATAII HDD.
My motherboard supports multiple level of RAID
I need to buy another similar if not identical hard drive.

Well the problem is, they dont sell my drive on newegg anymore. They sell an updated version of this drive for the EXACT same price and EXACT same specifications with one small difference. The newer drive supports Native Command Queuing and mine doesnt. Im not sure how identical the disks have to be to run a RAID array but i am extremely particular when it comes to PC's. Lemme know what you guys think. Also, if its any help i can give the model numbers of both drives.

Mine: WD1600JS

1 I want: WD1600AAJS

I have looked over the differences on Western Digitals own website and the only difference i can find is that of native command queuing.

I just built myself a new computer and will be entering into my first run at a RAID setup. I'm going to build mirrored array (RAID 1 I believe) with two 1 TB HDD (mirrored because a dead hard drive is sort of the catalyst leading to me building a new computer in the first place). But I have a few questions. One of the HDD has data on it that I want to preserve so I thought I would install both into the machine (without RAID), install windows on the empty one, copy the data over that I want to keep from the older one, format the older one, then reboot, enter the BIOS and then set up the RAID 1 configuration. Will this work? Will the mobo RAID controller then copy all the data from one disk to the other? Including the Windows installation? How does all this work with the MBR?

My second question is what advice others would give about partitioning my 1 TB drive. In the past I had a single 40GB hard drive that contained my OS and another disk that contained most of my program installations and my data. I was thinking about partitioning the 1 TB drive into partitions of 100 MB and 900 MB (100 for the OS and 900 for programs/data). Thoughts? should I partition at all? Will the RAID controller copy over the partition from one drive to the other?

Thanks for your help!!

A:Solved: RAID Question

1 - you can't do that. Setting up RAID will destroy all data. Once the RAID is running, you can replace a dead drive with another and it'll rebuild. So... copy your data to a 3rd drive... or get another 1TB drive. Then use the CURRENT one for an external BACKUP. Because remember, a RAID is not a backup from virus infection.

2 - Vista right? Study instructions for that... but basicly, you'll be setting up the RAID in its "BIOS". Boot with a OS-DISC, have the RAID drivers handy (I think vista is able to read off a USB key if needed, right?) with XP, you'll need to make a FLOPPY DISK (ARGH!) with the RAID drivers. In XP, you press F6 to tell the install you have a RAID... in vista.... dunno. After that, you can partition > Format and install the OS.

3 - Partitions.

Here is how *I* would setup a 1TB drive on my computer (I have a 500GB) for use of Vista/Win7.

C: (OS) = 50~100GB. (I'd do 50) - small defragging. For OS and Applications (Office, Quicken, Adobe, etc)

D: (Games) = 200~300GB. Only install games here! If reinstalling OS, the games and data are not wiped out. No or little defragging is needed. I have games that have never been reinstalled in 8+ years. Gone through at least 6 OS/PC upgrades/reinstalls.

E: Multimedia files. What-ever-space-is-left-GB. (700~800GB) Your music, videos, digital photos, etc.

Not sure if this is an XP problems or something else.

My experince has been with AMD with the motherboards, RAID, etc.

I'm trying to setup a RAID-1 with a P35 Chipset Gigabyte board GA-EP35-DS3R.

Gotta say, the setup software for the floppy is pickey (It wants to only run on its own board, so I installed WinXP-PRO SP3 on a single SATA 1TB drive, then turned on the RAID - which sees both drives, and configs for RAID1 without a problem. BTW, I also double checked this with a XP-MCE SP2 disc, same results.

But after telling the XP Setup which RAID drivers to use, (Included G-RAID) it reports back "No drives are connected to the computer".

I have recently installed Win7 to my old WinXP system, and I ran the Windows Experience Index tool on my system. All of the rankings were 7.0 to 7.2, except for the Data Transfer Rate which is 5.9. The pertinent equipment in my system is as follows:

ASUS M3A32-MVP mobo
AMD Phenom 9600 quad core CPU
4GB Corsair DDR2-1000 RAM
2 Western Digital Velociraptor 10,000 rpm HDD's

The concern I have is that even though these are not the newest top of the line hardware, I have always been under the understanding that with my hard drives set to RAID 0, and with them having the higher RPM rating, that the data transfer rate would be on the high end of the index. 5.9 on the index seems too low in comparison to the rest of my hardware.

The ultimate question is, could it be possible that a RAID 0 configuration may actually be working slower than if I were utilizing one of the hard drives as a stand alone drive without a RAID 0 configuration? Thoughts/tweaks/etc.... Thanks.

I have the opportunity to setup a RAID 0 array on my PC. I have 2 matching 500GB HD's @ 7200RPM. I am using my PC for work in the Office 2007 area and of course to play games, such as COD 4, Oblivion Shivering Isles, NWN2 MOTB, Morrowind with 2 addons, The Battle for Middle-Earth 2 with Battle against the Witch....

Will the gains be significent to load up RAID, or are the possible issues out weigh it???


A:RAID 0 or Not to RAID 0 -- That is the Question

If your HDs are the WD "raid enhanced" drives then maybe it would be a good idea to set up a slave array while booting from a single hd. your games would load 1.5x faster if they have not already been cached into dram by superfetch. And media production would benefit.

Otherwise no, a thousand times no! especially with critical Office data.

RAID provides minimal benefit for considerable instability. Separate drives can even be faster than a raid array (up to 2x). And you can transport data between computers more easily.

If your drives are not raid enhanced, then the aggressive error recovery techniques used in standard HDs can cause the array to lose synch, ie: all data.

raid benefits the hd manufacturers only. It is pure hype IMHO. But I stand alone on this one.

Yesterday while powering off my computer it was doing the usual windows updates and my 5 year old grandson decided it would be fun to start pressing everything on the keyboard.
The result was that when I came to boot this morning it wouldn't go past initial boot and was going around in circles. Eventually after F12 it came up with "No Operating System found".

So finally the questions:When offered the choice of installing windows, will this overwrite my current install and therefore all my settings?
I am now being showed the following screen (see attachment), which option do I take and will it destroy any data on my drive? I do have a backup on my USB backup hard disk but at the moment my computer is not seeing this drive.
I do have some limited knowledge of PS's so go gentle with me.

Hi there
Yesterday my computer was shut down when I returned home.  I may have lost power but I am connected to a UPS that should have kept me safe from any surges.  Turning the computer on, my RAID5 drive (drive letter M) is gone and a mysterious new drive
has appeared, labeled as drive E, also showing as a RAW drive. In disk management, I can see that drive M is its normal size, 11177.94GB.  I am using 4x4TB drives.  Intel Rapid Storage Technologhe shows all four
drives as healthy and functional.  Drive E shows in Disk Management the same as Drive M, and I have no idea how it ended up there and what I should do with it.  My C drive shows up and works normally, where I have my OS and programs installed.
Not sure where to start, but hoping it is just an issue with the MBR?

I have a computer running XP which was built with a pair of 80 GB hard drives which have met their limit in terms of free space so the user is wanting to upgrade. These drives appear to be running in some kind of RAID setup via the motherboards built in RAID feature (not a PCI card running this setup). This is the first time I've encountered a RAID setup in a home-based PC.

One other minor problem I have is this motherboard (an Asus ABN-VM) only has two SATA ports, which are both used, so I'm going to have to clone to an external drive as an image file and then connect the new single 500 GB drive and clone back from that image to the new drive. However, come to think of it, I have an adapter that would allow me to connect the new drive to the PC via USB so... scratch that concern I guess.

I decided to take the plunge and see what Clonezilla would do with the external USB drive I have and the two 80 GB drives in the PC. When the main menu appeared I told it that I wanted to work in device_to_image mode and then told it to mount all drives. It then asked me to select the drive I wanted to use as the source but it presented both drives as individual drives, not a single mirror as I was expecting the motherboard to present it as. So... don't know what to do from here.

Perhaps there's another cloning utility out there I could run from within Windows or could boot from a disc that would recognize this array and clone it to a single drive properly. Any suggest... Read more

Hi all,
My RAID 1 (I think? I have two equal drives that are mirrored) array was causing me a lot of pain. It kept freezing up my system and having me to had to rebuild the RAID too often. After a number of tests and browsing info online, I've decided that the RAID was the culprit of the freezing and BSODs that came once in a while.

Before deleting the RAID array, I went and used the Seagate (my HDDs) .iso file and used their diagnostic tool to check the drives. I did a long test of one of the HDD (Device 1) and it passed. I deduced that this was at least a good drive. I didn't do a long test for the other HDD (Device 0). But with both, after a short test, both passed.

I then went into the RAID manager (DOS-looking screen before Windows starts) and then 'reverted' Device 1 to non-raid. Then decided to choose 'delete RAID setup' for the Device 0. All good so far. I rebooted and Windows actually started fine. This is where I'm at right now as I type this. No freezing so far!!!

What I wanted to know is how do I find out which HDD Windows is booting off from? Is there a command line I can use in command prompt window in DOS mode to find out this info? It'd be great to know that I'm not on Device 0 since I haven't done a Seagate diagnostic long test on that one.

Also, I'd ideally want to have the second (Device 0) HDD formatted so that I can leave it in my tower and use it as an external HDD with Syncback. This is the closest thing I can have to RAID and I'm perfectly happy ... Read more

A:RAID - deleted RAID array, Windows 7 ok but I have questions

You can do into Disk Management and it will tell you which drive is used for booting. It will say it is active.

I am confused as to one part. You say you want to leave the second drive in your computer, but use it as an external. You can use one as your main drive, and use the other for backup...however a good backup process involves a drive that isn't readily available all the time. That being said, something like SyncToy from Microsoft will allow you to choose folders and on a schedule or manually, copy them to the second drive. I use this on my wife's laptop to keep her photos backed up to our server.

RAID has no place on a desktop system, so you are better off without it. But to get started, just go into Disk Management to see how your drives are configured now. Post a screenshot if need be.

I created a windows system image with the backup and restore utility built into win7. This windows install is on a single hard drive. I built and onboard RAID 0+1 array and used the windows 7 install disk to restore the image on to the new RAID volume. Windows starts to boot up but the screen goes black and reboots. The windows recovery screen appears and asks if I want to run the startup repair or start windows normally. I selected the startup repair. Windows goes through it's paces and tries to repair but fails. It says "NoRootCause" and the problem is likely caused by a recent system change or upgrade. I have the feeling windows needs some kind of RAID drivers or something. The onboard RAID is a P5W DH Deluxe motherboard. Any ideas? Is this even possible to do?

A:Windows 7 System Image - Restore Non-RAID to RAID 0+1

MetalliMyers, welcome to the Seven Forums.

Assuming you built the RAID while still using the single disk this is what worked for me when I was experimenting with RAID,

1. Install drives and configure the array

2. Boot to Windows and install the necessary RAID driver

3. Make a full backup after the drivers are installed

4. Used imaging program (at the time I used Acronis True Home, but should work with any imaging app) to put the backup on the array

5. Disconnected the single drive after imaging just to remove it from causing any problems

6. Started up and it booted to Windows

No promises but it should work. Failing that you are looking at a fresh install of Windows.
