1 of 2 Dynamic disks became basic in RAID-0 spanned volume

Q: 1 of 2 Dynamic disks became basic in RAID-0 spanned volume

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 $100 and find it also doesn't work for whatever reason. It might because it might create a single image from the two drives; which is what I need. Oh and I am now pretty certain it is RAID-0 so its not only spanned but striped across the disks which is why some of the photos I did recover on a single drive recovery look interlaced.

I have made a couple of backups using True Image and right now another raw sector copy using HDDGURU.com's tool HDD Raw Copy Tool. I have another 400GB drive I can use to try to fix the issue.

I also used True Image to clone the problem drive to a 1TB drive - I was able to make it a dynamic disk. Only issue is now that takes up a true 745GB of space and 1/2 of that is definitely blank or not correct. I cannot join the two drives.

Also no matter what I do, no piece of software finds a file system but oddly while scanning they show complete filenames and paths. They even identify the number of files and appear to read the MFT just fine.

Any ideas?

Preferred Solution: 1 of 2 Dynamic disks became basic in RAID-0 spanned volume

I recommend downloading and running DRP. It's a recovery tool that has been proven to recover files that most other programs have no luck with. I've even recovered files from freshly formatted or partitioned drives.

You can download it direct from this link http://goo.gl/v51TwD. (This link will automatically start a download of DRP that you can save to your computer.)


I created a dynamic disk on Windows 7 64 bit Professional ((6.1.7601) with all applicable updates verified 10 minutes ago) by connecting directly to a SATA connection on the motherboard.

I then tried moving the disk to my Startech drive dock (SATDOCK4U3E).  It is connected to my motherboard via USB3.0 connection.  The station has a e-sata connection by my motherboard does not.  Further looking at the newer motherboards, e-sata
seems to be rare now as there are no Z170 motherboards listed on TigerDirect or NewEgg.

If I buy an e-SATA card should I be able to use the dynamic disk on my drive dock?

I am wanting dynamic disks because I am moving all my DVD's and BluRay disks to hard disk.  I am setting up multiple shortcuts to the movies with the book marks being stored in folders for actors, actresses, and directors.  For instance, the African
Queen will have shortcuts stored under Humphrey Bogart, Catherine Hepburn, Robert Morley, and John Huston.  As my collection is quite large (over 8 large 500 slot folders of DVDs though some are not full like the only DVD folder), I am wanting to set
the drives as dynamic spanning.  The first DVD folder alone almost filled a 4TB drive.

If Windows 7 will not support this, will Windows Server 2012?  I am expecting before I finish to be using at least 16 disk drives and I would like to clone the drives to a backup set.  Also if Windows Server 2012 and I must move to it, does Wi... Read more

Is it possible to create spanned dynamic disks when one is the boot disk? I am getting conflicting info.
I have two 120GB SSDs and one is the boot drive and it is at 92% capacity, while the other is empty.
Problem is the empty is a dynamic and the boot is a basic. I have read that a boot disk cannot be spanned and to compound the problem I have to convert it first to a dynamic disk. I am running Win 7 Pro 64 bit. Is it better to just by a bigger drive?

A:Can a basic boot disk be converted to dynamic and then spanned?

A spanned volume cannot be used for either the boot or system volumes. They can only be used for a data volume. The problem is that a spanned volume cannot be accessed until the drivers are loaded and the drivers cannot be loaded until the volume is accessible. For that reason Windows won't allow it.

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?

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.

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.

I'm going to install Windows Seven so I had to make a new partition on my disk. Using Windows Vista's console, I made one but it converted my disk into a dynamic one.

What does this mean and is it dangerous? Can I dual boot Vista and Seven on the disk or what?

Local Disk Manager - Basic and Dynamic volumes

Is not dangerous, and yes, you should be able to dual boot Vista and 7. But, is a bit incompatible with the rest... just to quote something at a Linux board:

I have a computer with removable hard disk drives [ HDDs ]. 1 runs Win XP Pro Sp1; the other Win 2000 Pro SP4. The HDD racks are set as primary master & 2ndary master. The CD burner & DVD burner are set as slaves.

Both HDDs are WD 80 GB, 8 MB.

I created a "software raid" using Win7 computer management. The two HDD's are now in a raid0 array using a dynamic disk configuration. I have since decided that I do not want to have them in raid. I have tried several things to change from dynamic to basic including the tutorial shown on this site. I also used Partition Wizard Home Edition. Nothing seems to work. I even used device manager to uninstall the driver, but none of those things has changed the disks to basic. What is left to try?

Edit: By the way, there is nothing on the dynamic disk any more, so no problem with any method that will erase the data. Also, I have tried formatting the array, deleting it, and several other things. Another thing I noticed is in computer management - there is no choice when I right click on the array on the left panel to go from dynamic to basic. There was a choice to change to MBR or change to GPT, even a choice to go to dynamic (even though it was already dynamic). It almost seems like something is messed up.

I have win XP SP2 installed on an Asus A7N8X delux mobo machine (with a si 3112 sata raid controller).
I have an 120 Gb HD and have now just bought another one.

I have been reading about using the bios tool to create a striped set (raid-0). But all threads I have seen seem to suggest both drives then need reformatting.
I am hoping to avoid this, so I found some info on dynamic drives which allow you to set striped mode as well (from within windows xp).
There are 2 questions I have then, that hopefully someone can answer:
1. Will converting to dynamic disk and selecting striping in Windows XP allow me to avoid re-formatting and hence having to create huge backups?
2. Will this be the same as if I had created the raid set with the bios tool (performance and as seen from the bios) ?

Hope someone can help.



A:Dynamic Disks, Striping and Raid-0

1) Yes.

2) No. As far as I know, striping dynamic disks doesn't take advantage of hardware RAID controllers, at least by default, so performance will be lower. To BIOS everything seems the same as with basic disks.

A:Partitioning Error: Basic disk will be converted to dynamic disks

Hello cpsattawan. Welcome to the forum.

Don't convert the disk to Dynamic!

The are two drive file systems used for hard disks: legacy MBR (Master Boot Record) and the newer GPT (GUID Partition Table).

MBR disks can only have 4 Primary partitions. Any primary partitions added after 4 will require the the disk to be converted to a Dynamic Disk. Dynamic Disk is a supplemental system that lays over MBR. Windows can't boot from a Dynamic Disk. This system is used for data disks.

If you post a screenshot of your Disk Management window we can confirm this.

The easiest solution is to created an Extended Partition which will then contain Logical Disks. You can have many Logical Disks.
Partition / Extended : Logical Drives

Another solution is to delete one of the existing partitions. A common one to do this with is the Recovery Partition installed by computer manufacturers. What people do is burn the backup CDs of the Recovery Partition to keep on hand and then delete the partition, freeing a 4th Primary Partition for personal use.

A more complicated solution would be to convert the hard drive to GPT. But this process will delete all data on the disk so you need to be prepared with system Disk Images and personal data backups. You can practically have all the Primary Partitions you want on a GPT disk.

NB. Although my problem involves Unix, this is a Windows question.

Current Situation:
I have an installation of W2K Pro That uses two simple volumes (of 8GB and 5GB) of a 40GB HDD. I would like to install a version of Unix on some of the remaining space of this drive. At some point in the past, I decided it would be a good idea to 'upgrade' the HDD to being a dynamic disk. This does not sit happily wth installing Unix.

What I want to achieve:
I want to back up my entire system, including data, programs and system state, reconfigure the disk as a basic disk, and restore all my programs, data and settings, leaving the rest of the HDD to do what I want with.

My Question:
Will restoring my current 'System State' using NTBackup restore my current dynamic Disk configuration? If so, is there another utility I can use to restore my system back to its current state in every respect except the Dynamic/Basic configuration of the HDD?

Have a play with Disk Management in Computer Management, here are a few questions if somebody can enlighten me

1) What is the major difference between Dynamic and Basic Volume
It seems Dynamic volume can let you change the size of the volume up or down when there is an adjacent unused physical space, without impairing the files already stored. However Partitions (Basic Volume) can only be extended, and will always requires reformating.

Is there anything else I missed?

2) It seems that Dynamic Volume has a lot more overheads, so it may be a little slower and actual file stored will be less, any opinion on that?

I did notice one of the Dyname Volume started to show massic missing storage space, e.g. Used Space of 30GB only has 7GB realy files on it, absolutely no hidden files there because I created the volume. This happens after shrinking and expanding it up and down a couple of time, BUG?!! If so it is a serious one.

3) Dynamic Volume must be used for Mirroring?

I have Win 7 installed on an ssd drive and data on a 2 disc Raid 0 dynamic disk setup using Win 7 (stupid I now understand)
After a few crashes I decided to clean the dust from my PC, on reboot the OS started fine but no data. I discovered one of the raid discs was not recognised in the BIOS. I checked the cables, still no drive, I moved cables and the drive came back but this time no OS, system was hanging after CMOS back up success. I stripped the system down to basics (only OS drive, no Graphics card, checked RAM) and still couldn't get the OS back. I tried system repair using the DVD still no joy. I used a different HDD and loaded a fresh copy of Win 7 but it can't read the Raid drives. They are both dynamic and foriegn in disk management. I can also read all the data from the original ssd drive and that checks out ok with no errors but still won't boot. to top it all my back up drive has just died.
Is there any way to get the fresh OS to read the Raid drives? Should they be automatically readable?
Any Ideas on getting the original OS on the SSD bootable again? I'm wary of doing a fixboot or fix mbr as I don't know if this would affect the Raid recognition.

I have two partitions formed over two discs. After unplugging another hard drive I noticed that Windows would no longer recognized the drives.

I tried looking in the BIOS and discovered the motherboard didn't seem to be picking them up either. Thinking it may be a loose connection I unplugged and plugged them back in, seemingly fixing the problem.

However, after a few days, once again the drives disappeared from Windows, mid-boot. Unsure of what to do I tried a reboot, which seemed to fix the problem. This happened again after a couple of days and subsequently with increasing frequency until Windows would no longer pick up the drives at all.

After looking at disk manager I got the error messages attached. I tried 'reactivating' and then running chkdsk. As the drive I ran it on is large and contains my music (600gb, 10,000s of files), it took quite some time so I left it overnight. After checking on the PC chkdsk was gone and the drive was no longer detectable. I've repeated the process twice now. It's unclear if for some reason chkdsk is crashing and not finishing or actually completing its work in the time I leave it (around 12 hours).

Still, each time after I boot the PC the drives are viewable for a minute or two but files completely inaccessible.

There is a possibility that when I unplugged the drives that I mixed up the SATA cables and ports - is there a possibility that is what has caused this?

Either way, what would be the best way to get the data fro... Read more

A:Dynamic disc spanned partitions failing

It looks like one of the drives failed and your spanned set would loose all data, there is no redundancy in Spanned Volumes, unlike a RAID 1 or 5.
Hope you have a back up.
If not you can try to recover the files using the free TestDisk program. I have had the best luck with GetDataBack. You will need another drive of the same size or larger to restore your files to.

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!

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?

I have had a rather large problem over the last couple of days. It started earlier in the week, when one drive stopped working. Not a big problem, I've had drives fail before. 4 disks, so i can handle one less for a little while, i though. Not so though, while still waiting for my new drive, using my computer like usual (with less load on unit D) i suddenly start getting write-errors to D:, and the Intel Matrix Storage Console lists it as Stopped Working instead of Degraded. Nothing changed except for the status of the Volume, all the disks read the same as before, fully functional.

I have very little experience with these sort of matters. This is the first time I've lost a drive where i might lose data as well, and i have pretty much no idea where to go from here. I've tried to replace the faulty disk with another 500GB drive, but the RAID-setup in BIOS just tells me there isn't enough space, and the Console in Windows places the new drive as a Non-RAID drive. I can mark it as reserve, but that seems to be all i can do with it.

I'm not, hopefully, asking for miracles. I have just two things that i really need to retrieve from the Volume, my Firefox sessions (saved in a separate folder at the root of the drive), and my Thunderbird mail, (stored in their standard location, as my whole Windows-profile is on that drive).

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 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.

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.

Do you recommend "basic" or "dynamic" volume/partition method in Windows 10?

I plan to format a new 4TB HDD to be used for 3 purposes:

1. A secondary disk for windows paging file. Size = 3xRAM = 50 GB
2. Data drive (mydocs, music, video, photo, downloads, etc.) ~3.45 GB
3. Space for a image of my OS + apps of ~500GB

The OS and apps are on a separate SDD.


A:"Basic" or "Dynamic volume/partition method for HDD?

I'd keep the page file on SSD (you want it on the fastest drive you have) and have one partition on the new drive. There is no need to create a separate partition for system images - they can just go in their own folder.

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?


A:Windows Spanned Volume Survive a re-install?

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.

Scroll down to "Moving Disks to a Different Computer"

But as always, I recommend backing up Irreplaceable data first.

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

I would not bother. Spanned drives are PITA to backup, and if one fails life gets complicated.

Ok, so I got my Maxtor 300 Gig SATA Hard Drive and used the XP utility to create it. This is the first time I did that--I was so used to using Fdisk, I always did it that way in the past. Anyway, I'm using it as a data drive and followed the wizard in XP and ended up with a "Dynamic" volume instead of basic. I guess that's the default when you go through the wizard--I just kept clicling the "next" not even really paying attention to the choices as I usually do since I'm impatient!

Anway, I Googled and noted you need this for RAID drives and its not recognized in OS other than 2000 and XP, but is there any advantage to it? I'm not running a RAID configuration and my main OS disc is "basic". Does it matter? I can change it to basic it seems pretty easily according to MS article on it.

I'm hoping someone here can help. I'm very new to Raid, so you'll have to excuse my ignorance here. I'm using an HP pavilion p6210Y with 2x 2TB, WD Caviar Green's trying to set up a raid 1 array. I've reached the Nvidia raid array setup utility, and it appears I have successfully loaded the raid drivers.
After doing this, I inserted my Windows 7 x64 home premium install disc, and it sat on "Detecting storage devices...". After a few minutes of this, I was presented with an Error stating "No disks reserved for raid use, raid disabled." Then shortly after, switches to a message stating: "Reboot and select proper boot device or insert boot media in selected boot device and press a key."
I'm now unable to reach the Nvidia Raid setup, and unable to load the windows disc.

I'm certain the CD drive is good, as it works fine in another computer.

Do you have Windows on the drive now? How did you load the drivers? Drivers won't function without an operating system, so I'm a little confused about exactly what you did.

How did you run the setup utility? Does your machine support hardware RAID or are you using software RAID? Are there RAID settings in BIOS?

Is it possible to use 'dynamic' disc on a portable PC..?
As opposed to 'basic'...is it possible to convert a basic disc to dynamic in order to take advantage of the file system NTFS...?
I am reading in a Windoes XP book that this can't be done on a portable PC.
The ultimate purpose of this is to free unallocated space on C: drive which has 1.nn Gig of unallocated space.
Current properties of drive show 3.nn GB used spaced and 1.nn GB unallocated.

i have a 500gig primary hard drive for windows
2 320gig drives stripped ( using windows dynamic disks )
1 1.5t drive spare

question, can i add part of the 1.5t drive into the raid ? and use the remaining 1.2t ( ish ) as a seperate disk ?

will i need to partition the 1.5t first or can it be done through windows disk mananger ?

A:dynamic disks

Hmm... I don't think you can do that... RAID works at block level, meaning if you add the 1.5TB to the already stripped 2x320GB, then you'll be wasting the 1.2TB(-ish) and only use the 320GB off that 1.5TB disk... But Intel Matrix RAID can do that (IIRC)...

I'm new to this forum and I posted this in the XP section after a google search but think the question belongs here. I also did a search here without sucess.

I am dealing with a problem - I have files on an XP Pro dynamic disk and a computer change forced me to go to Vista Home Premium.

Previously, I tried to make a clone of the XP dynamic drive with Ghost and Acronis without sucess on my XP machine because I was concerned about random problems. I subsequently learned that neither program supports dymamic drives.

The Ghost people were no help but Acronis continued to work with me to resolve my clone delima. After numerous discussions Acronis sugested that I make a complete backup of the drive using one of their programs and then restore it. They said that I would have the opportunity to choose to reinstall as either basic or dynamic at the beginning of the process. Acronis even went as far as allowing me to DL the backup program. Unfortunatly the computer died before I could complete the process so I'm now stuck with files on a dynamic disk that I can't get to.

I also purchased a USB - IDE/SATA disk connector but dynamic drives are not supported on them in either Xp or Vista.

Microsoft took me down the wrong path with dynamic drives and I am a lot smarter now. NEVER NEVER again!!!

Is there any uinformation on this subject so I can get my files back???

Hi, First I'm new here. So sorry if this is in the wrong category. I also searched around and didn't see an exact answer to my question.

My set up: Windows 7 Ultimate. OS is not on a hard drive I want to span.

I have a few hard drives full of Movies. And currently I have to go to each hard drive to find the one I want. I want to be able to list all my movie hard drives as one drive thus they will all be in one place and easy to sort through. My understanding is since I don't a a piece of hard ware to enable raid I can use Windows Dynamic Disks to enable spanning.

What I want to do:
Enable dynamic disk spanning over 3 - 1.5 tb hard drives. Again none of these drives contain the OS.

So my questions are:
1. When converting a basic disk to a dynamic disk is there a way to keep the data?

I saw ways to keep the data going from dynamic to basic, but not the way I want to go. I don't really have a place big enough to back up all three at once, but I could back up one at a time if that would help. Not sure if all three need to be converted / added at the same time.

2. If one of the three hard drives fail will I lose all the data on all three disks or just the data on the one drive that failed?

If I would lose all the data, I'm not sure it would be worth doing it at all...

Is there any other way of doing this?

Thanks. I hope I gave enough background.

A:Using Dynamic Disks for spanning (what happens if one fails)

It's your call, but I would not want to entrust my data to a complexity such as dynamic disks. Would you still do it if you thought it had 1 chance in 100 of causing you major grief?

I'd just use a spreadsheet if necessary to keep track of the movies.

You might look here:




I found this blurb on the net. Make of it what you will:

"Although dynamic volumes can be used for expanding volumes it is
not recommended for permanent use. It is usually used as a temporary measure
on a server until downtime can be scheduled and a larger drive installed."

Currently I have this configuration:

Disk 0 (basic): WinXP (10GB), Unallocated (110GB)
Disk 1 (basic): Unallocated (400GB)
Disk 2 (basic): Win7 (500GB - raid0)
I would like to create one spanned volume from both unallocated partitions using the dynamic disk feature in windows 7. This way I can add space later if needed without having multiple volumes to think about. Also I hope that I will be able to quickly remove winxp when I don't need it anymore (waiting for updated software).

I currently boot into both xp and 7 with 7's boot menu.

To do what I plan I'd have to make both disk 0 and 1 dynamic and that would include the partition with windows xp. When I try to do this I get a warning that I will not be able to boot any installed operating systems on that volume after the conversion.

Is that the case? I really don't want to reinstall everything again...

Btw, xp put it's boot files (ntdlr, boot.ini) on the windows 7 partition onto which I installed 7 after xp without formatting it and that partition is set as the booting one in the bios.

Also, I found this here and it might help me but I'm not sure...
