Storage Pool Error: Drive or storage space Issues; check the Physical drives and Storage spaces sections

Q: Storage Pool Error: Drive or storage space Issues; check the Physical drives and Storage spaces sections

I created a Storage pool with the following setup. Three 3TB drives with parity all in an external enclosure with eSata and USB 2/3 ports. It was connected via USB when created and had production data loaded and tested without any issues.
After a few days of use I decided to see what happened when I tried to access it via the eSata port. No luck, due to a driver on the eSata card issue with Win 8. So I powered all back down and plugged back in via USB. At this point the Storage pool went
into the state as per the screenshot below. Any suggestions to either fix the issue and/or retrieve the data that is in the volume?

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)


Has anyone tried the new Storage Spaces feature in Windows 8? Your experience with it?

More specifically:

1. If this system is used on a shared network with other operating systems such as XP and Windows 7, can the storage pool drives be set up as shared, and become visible and usable from the XP and Win 7 machines?

2. If you have a Network Backup drive, like WD My Book Live, will it see and back up the Storage Spaces configured drive just like any other drive on the network?

A:Storage Spaces (Storage Pool) Experience?

I've only set this up on a Windows Server 2012 configuration therefore I cannot provide the exact steps on how to set one up in a client environment. That being said, a storage space/pool is essentially a virtual disk that resides on one or multiple physical disks allowing you to accumulate free space. For example if I have multiple servers with free space on their data drives I can then create a storage pool to accumulate this. To allocate this storage pool/space to a user or machine you will need to decide what you wish to do with it. Below are a couple of examples of how:

Share via Windows Folder Sharing (UNC Path)Use iSCSI to use the current ethernet infastructure allowing you to assign the storage pool/space a drive letter to the client machineIn a server environment you may wish to use it for DFS (Distributed File System) to maintain redundancy

Personally I use my storage pool as an iSCSI drive for which i have partitioned.

You can only use the free space of a non Windows install drive. To my knowledge you cannot overcome this with partitioning.

In relation to your second question, you will only able to use the share as a safepoint backup if it is shared via Windows Folder Sharing. For example: \\computername\share

Also you will need to make sure that the NAS is on the same workgroup as the Windows 8 machine hosting the storage pool otherwise it will not be able to find the share. Hopefully this is what you asking however pleas... Read more

Hello everyone!

I'm having the following issue with my Storage Spaces setup.

As you can see, Storage Spaces says "Reduced resiliency; check the Physical drives section" but all disks are "OK".
I do have some performance issues and a noisy disk, however, I'm not sure which disk and why doesn't Windows tell me whick one.

Any ideas on how to solve this?

Thank you in advance!

A:Storage Spaces "Reduced resiliency; check the Physical drives section"

Generally, when a member drive is disconnected or has failed, it might occur this error.

I would like to suggest you troubleshoot as below:
1. Backup the whole Storage Space to a new hard drive in order to avoid data lost.
2. Attach the disks to another computer to identify which disk that had a problem.
3. Format the disk that did not show up in Windows Explorer and was not readable.
4. The reformatted disk was then added to the original Storage Space and the rebuild process started automatically.Please remember to mark the replies as answers if they help, and unmark the answers if they provide no help. If you have feedback for TechNet Support, contact [email protected]

When adding an initial drive to a storage pool I get the error "incorrect function"
System: Proliant ML110 G4, Windows 8 64-Bit, 4GB Ram
I have a 160GB drive installed on the motherboard's controller which hosts the OS
I've installed a single 2TB drive on a 2 Port PCI Express Internal SATA II Controller Card (JMB36x).
As soon as I create a pool using the 2TB drive I get the error "Incorrect Function" and the drive becomes RAW.
The drive id's are unique.
It's worth pointing out that the system without the new controller can only support 2TB max of SATA drives, but this is bypassed by the controller card I added?
Help is appreciated.

Hi All,

When creating a Storage Spaces Pool, the member drives are no longer listed in Disk Management.

My system has been hanging every so often and when I checked the Windows logs, I see a lot of critical error messages about Harddisk/DR10 having a bad block. Since Disk Management no longer lists the individual pool drives, how do I find out which DR10 is one of the pool member drives?

I've tried mini partition tool to see if it can see the drives, it doesn't. It can only see what Disk Management sees and that's only non-storage spaces pooled drives.

Many thanks!

In the Storage Pool section, I get this error message:
Drive or Storage Space issues; Check Physical Drive and Storage Spaces sections.

In the Storage Spaces section, I get this error message:

Error Inaccessible; check the Physical Drives Section

In the Physical Drives section, all 4 2T drives are checked as okay and have either 49.6% of their capacity used or 49.8% of their capacity used.

These drives are in a 4 disk enclosure that can be attached either by eSATA or USB 3.0. I get the same error under either attachment method.

I am guessing that the virtual disk information, metadata, is corrupt and the data on the four drives is not recognized as a storage pool any more. The device manager shows the disks individually, and the storage pool. is not recognized. In the Storage Spaces section of the Control Panel, the storage pool is recognized, but inaccessible.

Since the data on the disks appears to be good, is there a way to rebuild the virtual disk data. Parity is the redundancy method.

Thanks, in advance, for your help.

I had 3x 3TB drives in a parity pool. It started to fill up so i added a fourth 3TB drive and months later one of the original 3 began to fail on me. Performance was slow, then slower, then it showed disconnected.

I retired the drive and added a replacement, literally the same model 3TB drive. I cannot however, get it to remove the failed physical disk and repair the pool. I even tried adding another 2TB drive i had available in case it needed the extra space (didn't make sense but i was reaching).

I get the "drive could not be removed because not all data could be reallocated. add an additional drive to this pool and reattempt this operation."

Any ideas on what i need to do? I have searched a lot and don't really seem to be getting anywhere. The only way i was able to retire the drive was through powershell. I'm assuming it's a GUI issue and perhaps i'm not approaching it correctly via powershell. Attempting to repair virtual disk didn't work.

Any help is appreciated! I really don't want to lose this data. I wasn't able to backup much before the drive failed completely.

I've searched but not found an direct answer. Pls excuse if I have missed something.

I'm running a Storage Spaces on a Win 8.1 machine with a few partitions. I just discovered that my large partition couldn't be enlarged over 16TB due to my 4kb cluster size so I created a new, smaller, partition on the drive capacity that I had left with
64kb cluster size. Fine so far. I then started moving files to the new partition thinking that I could somehow reclaim the unused space from the old, large, partition and then "transfer" it to my new, smaller partition. But now I'm stuck as I can't
find a way to reclaim this unused space. Help!
I've tried running the "Defragment and Optimize Drives" tool but no change.
What am I doing wrong?

The idea of creating a large redundant storage pool seems like a good idea (I can finally get rid of FreeNAS box), but before I do that I have couple of simple question

1) Can I move a pool created on one windows 8 machine to another windows 8 machine?

2) what happens if disk where my OS resides crashes or I feel like re-installing windows 8 on a different set of hardware, will I be risking losing all my data if OS or hardware changes force me to re-install windows 8?

If the storage pool is independent of the OS disk it shouldn't matter if you need to reinstall. Storage pools themselves offer resiliency through striping and mirroring, if enabled.

You might want to take a read through this for more information.

I have a 4x 2TB drive storage pool setup with storage spaces under parity mostly used for movies/tv shows. I decided to buy 2 more 4TB drives and add them, but I only have space for 1 more at the moment (only 6 SATA connectors on my MB). After adding it (and appearing successful), it attempted to rebalance but eventually stopped changing the %complete and Storage Spaces eventually crashed. I tried again with my second drive, and the same problem. If I do "get-storagejob" in Powershell, every time i boot up it has 3 jobs (screenshot in linked Imgur album) and 2/3 of them always fail at 42%.
I've tried removing both of the drives that failed to add (crashes), I've tried cancelling the rebalancing (crashes), and many other things but Storage Spaces continues to crash as soon as those 2 jobs reach 42% or I do anything to change something.
Data on the drive appears accessible, but any attempt to view results in eternally spinning progress bars (sometimes a second or two of video before sputtering out). I'm usually pretty good with Google and can solve my own problems but this has had me spinning my wheels for days.

Hi. Can anyone help me? I am really concerned I may have lost the contents of the Storage Space I have created in Windows 8.

Having read an article by Woody Leonhard extolling the virtues of Storage Spaces and how it could take over from Windows Home Server,I began the transfer at the end of October. I started with 8 HDDs, most 1.5 or2Tb drives, but there were 2 @ 3Tb drives which I had been using elsewhere and which were already formatted as 2.72Tb. The transfer process was going well and I had got almost ? complete, with about 18Tb transferred on to the storage space based on a now grown pool of about 15 HDDs.

The Storage Space ? it was on a ?parity? basis- was ?all green?, although I was often prompted to increase the number of HDDs as the transfer progressed and all new HDDs had been successfully assimilated (Borg like!). The problem arose when I tried to add a new 3Tb Seagate HDD. It was only recognised as 2Tb and so I attached it to my main PC and formatted it via GPT and got 2.72Tb showing. I then put the HDD in the Win8 machine and in ?My Computer? it appeared as 2.72Tb. However, when I sought to add it to the Pool, the applet showed the HDD as being only 1.99Tb. Back in ?My Computer? it confirmed the HDD was 2.72. I thought it might just be a minor bug in the applet and clicked to add the HDD to the pool, but having done so, the overall size of the Storage Space only increased by 2Tb, not the 2.72 I expected. I immediately hit the? remove? button before anything... Read more

A:Help: Windows 8 Storage Spaces and 3Tb Drives

Sorry you are having problems with this. I was not running a Storage Spaces until you posted and then I decided to try it using 2 640 GB drives. Not many of us have 15 hard drives laying around.

None of us would want to be responsible for you loosing any data, so any suggestions should be vetted thoroughly before you take any action.

Considering the info you have given, I would try to add the last 3 TB drive and see if it can be incorporated, and don't worry about its size just yet. The Storage Spaces utility seems to format the drives, so being pre-formatted may not make a difference to it. Also, there may be some requirement by the utility to balance out the space for consistency. But I would guess right now, your primary goal is to remove the red notification on your space. Would you agree it is probably the result of the 2, 3 TB drives being shown as "disconnected"?

I will hope, that because the drives show as disconnected, the data was maintained on the remaining drives. Is there any way you can tell for sure?

So, some questions. of the 15 drives, how are they connected to your system?

Are you using a UEFI or Legacy install? My drives were configured as GPT by the Utility, but I run UEFI.

Now, my tests:

I had to test using a Mirror setup, since I only have two drives. You need at least 3 for parity. If I can find another drive, I might try that later.

But I created the pool, shut down the system and removed the drives. A reboot showed no... Read more

I'm hoping someone here might have experience with mirroring 2 drives in Windows 10. I'm reading How-to's but some of my basic questions remain unanswered.

I have an SSD (C) used for the OS and loading apps and a 2TB drive that holds for all my files, images and videos, etc.

I want to add a second 2TB drive and create a Storage Spaces 'Mirror' setup to offer redundancy in case the D drive fails. (I also have off-site of backups). From what I've read the mirrored drives will need to be formatted so I will have to backup and re-copy all the current data onto the Mirrored set.

But here's the question:

Will a single mirrored drive behave like a single drive if it's removed from the set and connected to another computer?

Does the file and folder structure of one of those mirrored drives offer access to the files if it's removed and accessed using a removable SATA dock on another computer?

Thanks for any help with this question.

I have a storage space consisted of 3 X 2 TB hd drives in parity mode. I used the drives writing 3,06 TB of files, that means I didn't used the whole available disc space (actually 2 X 1,81 TB available and 1 X 1,81 TB as parity). I added a new 2 TB drive to expand the array. But windows calls me to add 3 drives not 1 (as I did) and keeps saying I' m using 4,6 TB. I double checked the capacity of my files and it's indeed 3,6 not 4,6 TB.
I don't understand what happened. Are my files secure? Is there a way to check the health of storage space?

Let's get this clear right at the start, I manage servers for a living and I understand RAID arrays and storage pretty well. i know the differences between RAID 0,1,5,6,10,50, etc.

In playing with Storage Spaces on Windows 8 and using a resiliency type of parity has left me confused as to how the drives are filling up as fast as what they are.

In my lab, I created a Windows 8 VM, with 3 x 4GB additional drives. So, 12GB of RAW capacity between the 3 drives.

So, I created a Storage Pool using all 3 drives and am left with a total pool capacity of 9.75GB. It seems that about 750MB of each physical drive is consumed by overhead, leaving me with actual usable space of 3.25GB per drive.
So, I created a single space, used Parity for the resiliency type. I set the size to 6GB, so that including the parity information, only 9GB would be consumed. Thus, I'm not using "thin provisioning", but instead ensuring that I have enough capacity to actually store my data.

My confusion starts here. Even though I'm not yet storing a single file, approx 35% of my pool is being used. So, considering it's parity, and RAID (Raid 3 specifically from what I have read), I have to assume that it's just visually showing me that 1 out of my 3 drives will be used for parity, and thus nearly 33% will be consumed by parity.


A:Confused on Storage Spaces with Parity and free space

Adding Insult to Injury, I tried a 2-way MIRROR with Storage Spaces

Added 2 x 6GB drives to my machine, created a New Pool, created a new 2 way Storage Space pool. As expected, .75GB on each physical drive was unusable as a result of overhead...so my Pool provided 5.25GB on each drive, x 2 drives, so 10.50GB total.

And since I was using 2 WAY MIRRORING, I expected to only get 5.25GB of total usable space.

However, after copying the 7 files that are 4GB from above, my storage space went offline and said it was FULL. WTF???

You can see that Explorer reports things correctly, I have free space. My 2 way mirror drive is not 100% full.

My original goal for my Server was to have one giant Storage Pool with separate folders for Videos/Pictures/Documents/VM img/etc... After using this model for the past year, I have found some operational deficiencies with this methodology. For starters with one Storage Pool that meant I would have 16HDD's spinning 24/7 which is an excessive waste of energy and component lifecycle. Another issue was heat, when these HDD's were all in my desktop case I actually had to remove the side cover and cool them with a 12" desk fan (Ive since moved to a Norco 4224).
My new goal is to break up the server into 4 separate Pools. The problem comes in when I'm trying to dismantle my huge Storage Space and reallocate the HDD's to a completely separate Storage Pool. FYI Storage Spaces is not designed to reduce drives/capacity, it only works great when adding drives/capacity. Currently I have shuffled some drives around and managed to separate the main folders into their own Storage Pools. After I copied all the data from my original Storage Pool to the new, I would then delete the original files (10+TB) on the original Pool. Here's the bug; The files would be deleted from the Storage Space (the virtual disk), but the space would NOT be released from the Storage Pool.
What I mean by that is, my Storage Space (E:\ drive) shows that it only has 8TB of files (since the Pool is in parity that would take up 12TB in the storage pool) However, my Storage Pool (made up of 12HDDs) is sh... Read more

A:Storage Spaces error

I will attempt to help, assuming your Storage Space was set up as a Two way Mirror. If you did not use resiliency, let us know. The fact you cannot access the space in Explorer does not look good.

Since your drive shows as disconnected, do you know what caused it assume that state? Did you move it or add any drives?

The best option is to reconnect the drive and allow the Space to be rebuilt. But even with one drive showing as disconnected, I could still access the files in Explorer. It you are not running a Mirrored or Parity Space, the files may not be accessible.

The second option would be to add another drive to take the place of the one lost. After you remove the disconnected drive, the Space should rebuild itself.

See the attachment for a progression of having a drive fail. The total Pool space available should always be a consideration, and a Mirrored space needs twice as much available space as the data filling it.

Storage Spaces/Drive Pool makes independently checking each of the data hard-drives impossible?

I am setting up a new home PC\Server and decided to use Win 8.1 since I needed to upgrade to at least Win 7 Professional to use Disk Mirroring. Now I find out Win 8.1 has Disk Mirroring (From Disk Management Console) and Storage Spaces.

My question is which one is better and faster. I just want to mirror two drives (RAID 1) to store my pictures so if one drive fails I have a copy. I'm not interested in expanding this or adding drives that Storage Spaces seems to support.


A:Win 8.1 Drive Mirroring VS Storage Spaces-which is better

Basically, if you just want to stick with mirroring, just stay with RAID 1. You can also do Storage Spaces and set it up to basically act like RAID 1, but I can't tell you if one is faster or not. I'd imagine both are the same, that is of course unless you have a RAID card with a dedicated processor.

Hello everyone,

I have a windows 8 machine that acts as a media storage computer on my home network. It has 8 storage drives varying in size from 1 to 4 TB. I have been using Drive Bender to create pools, however am interested in switching to Storage Spaces.

Currently with Drive Bender I have created several pools for storage of different media (movies, TV shows, Audio, Photos). Each pool has several drives within it. There is no replication of the files within the pools. They are configured as JBOD with 1 mount point.

Since I have no replication of files I need to be able to get files of of a drive if something happens with the program that manages the space. Drive Bender does a good job of this and I never feel like I will lose a file if Drive Bender breaks.

1) Can I get files off of a drive if Storage Spaces "breaks" and how would I do this?

2) Drivepool (not Drive Bender) has several options that allow management of how data is written to the pool of drives (such as filling 1 drive then moving to the next keeping files together). Is this an option with Storage Space?

Thanks for any help you can provide me.

Windows 8:

It spins up, bios sees it, I'm 100% sure no damage was done to the data as the drive was off when the power plug was broken. windows sees it but storage spaces thinks it is a new drive. So spaces is still showing the raid0 offline and raid1 in lowered resiliency mode.

I believe I lost my boot drive. My computer hangs when it can't find SATA4 in BIOS. I tried switching cables, but it did not help. I have 4 drives in a storage spaces array and a single boot drive. The computer is older, so I am thinking about pulling the 4 drive array and putting it in a mediasonic 4 bay box. I would attach it via usb to a windows 8 laptop. I only use the array for media storage.

Will the laptop see the array correctly in the usb box?

A:Boot Drive Failure with storage spaces array

So I went ahead and bought the mediasonic 4 bay box. I put in the 4 drives from the array and they showed up without any problems on my windows 8 laptop. They are linked by USB, but still show up as a regular hard drive.

I'm trying to create a system image (Control Panel\System and Security\Backup and Restore (Windows 7) -> Create a system image), however my storage spaces drive is not listed in the available selection to save the image to.
Why is that and what can do about that?

Thank you.

I am really interested in drive pooling as I have a computer running windows 7 now that has 5 drives (3x2TB and 2X3TB) that act as my home media storage center. I have TV shows split between 3 drives and movies on 2 drives. When I access these from other applications, it can be hard to group everything together and if I run out of space somewhere, it is a nightmare.

Win 8 pro x64 is on it's way, but wanted to know how to set up Storage Space. I have looked through the tutorials, but cannot figure out how to set my system up, if I have media in different spots.

Do I create 1 Storage Space and all 5 drives are in it then I just have to point to if from my other applications to get to the data? Do I create a storage space for each type of media (music, TV shows, Movies, etc.)? When I add a drive to a storage space, how do I get it to include the files within the storage space and not just use the "empty" drive space?

I am not looking for redundency protection, but to make my handling of data across all the drives easier (e.g. "Did I put my Futurama series on drive 1 or 2...Did South Park make it on to one drive or did I have to split it up?)

Hi can you not dedicate 0ne or both of the 3Tb drives to video/audio. If you could then everything would be on one drive and I would guess each would take a lot of DVD's / downloads

Apologies if this has already been covered. I did try a search but got nothing specific to my problem.

I currently have 4 Windows 8.1 Pro units around my desk.
One is general day to day.
One is gaming, audio & video work.
One is a currently retired 'server' for backups.
One is the replacement 'server' for backups.
This contains an SSD system disk, a 2Tb HDD for Macrium Reflect images and 2 Storage Space pools.
One consists of 2x250Gb HDD's called DATA & assigned to drive letter 'D'.
The other consists of 4x1TB HDD's called STORAGE & assigned to drive letter 'E'

The replacement 'server' unfortunately decided to go do-lally :(
All I know is, it suddenly decided to reboot 4 days ago and everything went haywire.

As a result I purchased a new motherboard, CPU, ram with the intention of building a fresh install of windows 8.1 on the basis the storage pools would show up in the new system.

Here is the problem !
The pools show up in Control panel /Storage Spaces as DATA (F:) and STORAGE (G:)
Both pools show as OK and all 6 drives show as OK.
If I click on 'view files' nothing happens :(
If I go to windows explorer they show up as Local Disk (F:) and Local Disk (G:)and if I double click to open I get a 'Location is not available. F:\ is not accessible. The volume repair was not successful'. Same for G:

Why is Storage Space manager saying they are working properly when nothing else can access them?
Are they recoverable somehow or have I lost everything ?

I've posted on the problem I'm having with my Storage Space (set to file 2-way duplication) before.  I know I'm going to lose some files.  I removed one drive to reformat it to a larger clustersize and, while the array was repairing itself, I lost
a 1TB drive that will no longer connect.

I've "Removed" the drive and gotten the error "Can't remove the drive from the pool" because "...not all the data could be reallocated.  Add an additional drive.."

I already can't re-add the old 4TB drive (even though I've done nothing to it) because Storage Spaces says it's now an "unrecognized configuration".  At least a disk recovery tool can find files on it (though they're all named nnnnnn.JPG or nnnnnn.AVI
or nnnnnn.DOC)

However, my 15TB array (X:\) can't be seen because it thinks it's lost two drives - fair enough - and even though I know I'm going to lose some files (the most important of which were backed up in File History) it refuses to allow me to remove the faulty 1TB
drive.  I added a new disk and it STILL won't let me.  

How can I get my X: drive back? All of the disks in the array are 40-60% full - there's PLENTY of space to duplicate the files that ARE down to one copy!  What can I do?

(As per a suggestion in my other thread, I tried a System Restore to before the point where I'd Removed the 4TB drive and that didn't help since I couldn't select the X: drive to restore!)

I have a storage pool set up on my Windows 10 PC
The storage pool is a total of 6.5TB at the moment with 2.7TB of Data on it
I'm getting the Warning "Low Capacity" add another drive
When looking into it, when I set the drives up I set them to "Parity" which is obviously increasing my usage on the drives.
How do I change the Resiliency Type to None.
I'm fine with this as I monitor the drive's for any failure issues on a regular basis

Trying to add a formatted slave drive (IDE) to the storage pool or even making a new storage pool, the following error occurs "An error occurred and the operation might not have completed". In more details, it says "access is denied. (0x00000005)"

A:Access denied when adding drive to storage pool...

I figured out why the error occurs. In order to add or remove drives in a storage pool, the volume needs to be deleted in disk management. So IDE drives can be added into the pool. I was having "access is denied" error both adding and deleting to the spaces with IDE and SATA drives.

Windows 8 64 bit

2 wd my book 4tb drives
I can see them in disc management as dynamic, and am able to write to them.

I use "storage spaces" from control panel, and that's how I end up with the notice quoted in title line above.
Any ideas?

A:"no drives that work with storage spaces are available"

Dynamic disks are NOT eligible for being added to a storage pool. (See:
: though it refers to Server UI, the underlying restriction is applicable to both client and server).
You must convert the disks to basic disks using Disk Management UI before they will be usable with storage spaces. Note this process deletes all data on the disks that you are converting.

I'm creating a new Storage Space with two internal drives, a Toshiba 2TB and a Toshiba 3TB. The 2TB drive was successfully added to the storage space. However, adding the 3TB drive results in the following error:

"Can't add drives. Check the drive connectionis and then try again. Incorrect function. (0x00000001)"

Does Storage Space have a known issue with 3TB drives? I ask because I've run into this problem with Windows Server Backup in Windows Server 2008. I thought Microsoft would have rectified this issue with their latest OS release...

Any help / advice will be appreciated.

A:Can't add drive to Storage Space

I've seen similar reports, but the issues were caused by the disk controller. The drives had the same Unique ID, and that's what had Storage Spaces confused.

Check it in PowerShell and post results:

Get-PhysicalDisk | ft FriendlyName, UniqueId -auto

This is probably a dumb question, but, having created the pool, how do I put stuff in it? When I check the External Drive (d in my case) it says the file is empty .
Also my computer will not boot up until I detach the external drive. This has only occurred since I created storage places. What have I done wrong ? The last item in the screen shot (Toshiba) is the external drive

A:Storage Spaces

i think you need to make sure the computer harddrive is first in the list of drives to boot to in the BIOS ,to fix the computer not booting when the external is plugged in .
and to use the drive for storage you will have to add the files you want to save to it there yourself

Storage Spaces are a very intriguing part of W8. I'd like to give them a try. From what I've read if I try to use Storage Spaces on drives with files the files will be deleted. Is this correct?

If I move my files to another drive that's won't be part of my pool, can I then move them back to my new pools and have them on a drive with the same drive letter so the programs that use them can access them?

I would probably be using my F and G drives to use Storage Space. I assume I can give the pools the same drive letters then move the corresponding files over to them and my programs will be none the wiser that they are part of a Storage Pool?

A:Storage Spaces

Storage Space is quite interesting and I've spent a fair amount of time playing with it. And in the event that your host computer dies, you can simply pull out the drives, move them to another Windows 8 host and the system reads the storage spaces metadata baked into them and reassembles on the next computer without you having to do anything.

Yes, when you setup drives in your pool, it's going to format them at the start..so files would be wiped out. Copy them elsewhere and then copy them back.

Correct, you can assign and change the drive letters associated with your pools. And the programs are none the wiser as to which type of storage they are on.

I currently have 9 TB of data on storage spaces. I have it setup as a simple storage with no redundancy. I would like to add a new drive and pull out an old drive. I have followed many tutorials to do this but nothing seems to be working. I tried to mark the old drive as retired and remove it but windows will not move the data off of it. Is there a better way to do this? I am familiar enough with powershell so if I need to use that I can. If I knew it was going to be this hard to remove a drive I would have just used drive bender. Is there a way to take my existing storage pool and convert it to another program or go in at the drive level and move the files off the drive I want to drop?

Thank you

I have two drives (750 gb each) in a hardware mirror raid which the contents are very important to me. I bought a 2 TB drive which I created a new storage pool. I transferred all the contents from the hardware raid to the new storage pool (the 2 TB drive). Can I add a two way mirror to the storage pool (or convert the pool to mirror) after if I format and add the two 750 gb drives? When I created the pool, I did not have an extra drive to use for mirroring so I had to select the "none" option for resiliency.

A:Storage Spaces

I am sceptical of mirroring. It takes extra real time during operation and wastes a lot of space.

With all that disk space I would setup partitions for the data and image those. You can schedule that for as often as you like. It runs in the background and compresses the data. That way you use only about 60% of the space.

Hello, I am transferring all my data away from a WD MyCloud and moving it into my desktop. Currently I have 2 3TB drives in the MyCloud that I will be installing in the desktop after I move everything over. Well, I was almost done when the storage space filled up. So I plugged in a 500 GB drive temporarily and attempted to move the last 10GB of data over. It is still saying that its full and won't let me transfer it. I also tried deleting a few large files, but its still not letting me do anything. The 500GB drive is in the pool showing just a few files. Is there any way to rebalance the drives? Thanks for any help.
