Windows 10 storage pool errors.

Q: Windows 10 storage pool errors.

So I recently bought a new external drive to replace my old one. So I recovered most of my data from my old drive then went to create a new storage pool with the new one.
But when I do so, I get an error message saying "Can't prepare drives- close all applications using the drive." (Error code is 0x00000005) Is there a way for me to fix this or not?
To help further the drive is a seagate BUP slim SCSI drive 1TB. It's formatted as a backup, any answers for this problem is much appreciated.

Preferred Solution: Windows 10 storage pool errors.

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

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

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


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 had to reinstall Windows because of a corrupted MBR and the Windows OS drive suddenly became a GPT drive. Once Windows was reinstalled my storage pool was unrecognized and I was given the option to reset. I was not ready to do that. Then when Windows
was updated and now it shows no drive. But I can pull up the data drive and able to create an image with Patrician Guru. Before I do that or that or just wipe the drive. Is there is any way to reinitialize the pool?

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

Yeah so umm . . . my OS HDD died yesterday, and my other two drives are in a storage pool together (thus not bootable) after two days of trying to set up a dynamic partition in the pool using diskpart (which I'm now fairly confident can't be done XD) was wondering if there is a way to simply delete the storage pool with the tools you have available on the usb boot installer from the iso.

Otherwise I'm going to have to wait until i can buy a new HDD, which in my position could be a very long time, well, unless there is a way to make the thing bootable as is that I failed to think of. There isn't exactly any help on this topic available yet (I may be the first to hit this for all I know, heh heh)

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

Hi there,
i created a storage pool on windows 10 (goal was actually to create a windows firendly RAID0). Problem is when i plug it on a windows 7 machine, i can see disks in the disk manager but the Storage pool it self is not mounted. I cannot access the storage

Good Morning!!
Could any suggest me to overcome the below scenario.
We are unable to add the new physical disk in storage pool without stopping the cluster service. I have noticed that StorageSubSystemFriendlyName has different naming standard initially and it got changed post the cluster service stop. 

Below power-shell command works post the cluster service stopped.

I have a spare computer running windows 10 pro, running as a "server". I have added 4 1 tb harddrives and pooled them to have one storage space of +/- 4tb. my question is, If one of my drives fail will the whole pool be gone? i ask because i had created the pool and then the computer had some issue so i disconnected the 2 new drives that i had put in and restarted the computer ( at this point only 2 drives were connected out of the 4) but the pool storage space wouldn't show up, after reconecting the 3rd and 4th drive the pool showed up. is there any way i can save my data in case of one drive failing????

Windows is really making me upset lately, with the forced windows 10 upgrade dialogues  and all. Today I got some hard drives in the mail along with a usb enclosure all together 5 drives 4TB each. From what I understood windows storage spaces was
supposed to be similar to raid. I heard there was something like raid 0, 1, and 5 so I thought this would be great I could have 1 big 20TB drive. So I went to set this up and the first thing I noticed was the raid 0 was nothing like normal raid 0. There is
no speed increase it just morphs all the drives into one drive with no performance increase and all the chance of data loss without parity. So I decided to do 1 disk parity, oh boy doing that let me have only 12TB of usable space as 6.1TB went to redundancy
for 1 disk. I really don't understand that as in normal raid 5 only 1 disk would be used for redundancy but in this case almost 2 full disks out of 5 are being used for redundancy. Anyways the major issue I have is the whole thing is being spun down and put
into some power saver mode every 2 minutes regardless of what I have things set to. I turned of hard disk spin down in power options, turned of usb power saving in power options, and a tried to use a tool that claims to keep disks awake in windows. This is
really getting me upset as every few minutes when I go to use my external hard drive I have to wait 30 seconds for all the disks to spin up in the storage pool and for windows to recognize it. This is not mak... Read more

My question: can I get away with only adding one 3 tb drive without losing my current data? or do i need to add 3 drives as windows is indicating?

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.

My organization is currently using Netware 6.5. We need to expand our Groupwise storage pool (currently 200 GB) by 200 GB. Unfortunately, we're not well-versed in Novell and we don't know for certain what the maximum pool size is for Netware 6.5. The system is left over from a previous net admin and I've been combing through the Netware Administrator's Handbook, but I'm not finding it. If anyone knows this information or can direct me to it, I would greatly appreciate it.

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.

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

Thats because you only can choose a maximum pool capacity of 10.9 TB.

I was setting up a test storage pool consisting of five 2TB drives. I set it to parity and was surprised to see how small my storage pool was. I'm not sure how the inner working go but I thought I would suffer one drive worth of space to parity but it
is much more than that. Five 2TB drives totals to a little over 9TB total (stupid measurements) but when I set it to parity I only get about 6TB when I was expecting closer to 7.25. Why so little? How does Windows calculate parity for a storage pool?

Hi all,

I have been looking at building a NAS for my home and I have noticed that Windows 8 now contains a pretty decent system for protecting my drives (I'm talking about the Storage Spaces feature).

I know we have had Raid 5 support in the past but I very much like the idea of being able to grow the "Storage Pool" by replacing the drives with larger ones when they die and eventually being able to make use of the extra space.

Once of the most important things to me is HOW the user get notified when there is an error on the array (Storage Pool). I have been playing with yanking out drives while writing data and the scary thing is that the system doesn't actually alert you anything is wrong except for the tiny 'action center' flag appearing in the lower right hand corner of the screen. The other kinda annoying thing is that this flag doesn't show anywhere on the Start Screen, only on desktop mode.

LASTLY, another scary thing is that even if you do notice that a message has appeared in the action center, you are told that the drive missing or failing ISN'T a high importance issue!!! Its a general maintenance message ??

So my question is, does anybody know a better way to get these action center messages? I googled for email notifications from the action center but found nothing. I suspect this is because the action center has been a fairly useless feature of Windows until now.

Or alternatively, can anybody recommend a better Storag... Read more

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.

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!

I added 2 new exact same 4 TB drives that I want to set up as a software raid 1 to prevent loss of data if a single drive fails. It should write the data to both drives at the same time. This should be straightforward to set up - under control panel - storage spaces - create a new pool - select the drives then add them to a "storage pool" and select what type of raid.

These are blank drives - after I select them and try to add them to a pool I get the error "Can't prepare drives" - "Close all applications that are accessing the drive, and then try again." "Access is denied. (0x0000005)"

Nothing is accessing the drives...........

I went into control panel - administrative tools - computer management - storage - disk management - and deleted the volumes from both drives, so they are no longer formatted - now I get a different error message "Can't create pool" - "Check the drive connections, and then try again." - "The request is not supported. (0x00000032)"

I use this computer personally at my house - I just have important data that I don't want to lose and this is a great feature built into Windows 10 - but I cannot get past this point of adding the drives to the pool.

These were initialized as GPT disks because of the capacity. Bitlocker is off, and no other encryption.

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.

Hey Guys,

I keep having BSOD's I did a upgrade from win 7 to 8.1 then I changed hardware in the comp so I was getting lots of BSOD's (I changed CPU motherboard and ram).

I did a bit of investigative work and found some drivers to be causing them so I did a clean reinstall of windows 8.1 and it got rid of most of my problems. Now however I use XBMC for my frontend as this build is an HTPC and if I alt tab out of xbmc to do something else, chances are good that I'll get a BSOD. Its about a 1 in 5 chance it'll BSOD

It's almost always bad pool header or some kind of 'pool' problem. I've also noticed in my bios it says I have 4gb of ram however in windows it says I have 2.

I'm wondering if it's a ram problem? I've run memtest for about 20 minutes no errors (I know thats not long enough I'll run longer later) Also, memtest doesnt immediately see my second stick, it takes about 3 - 5 seconds before it see's the second one, is that normal?

I can post crashdumps let me know if you need me to, and what ones to post.

Also CPU-Z says I have 4GB single channel windows 8.1 system settings says 2GB

Dear Forum Helper

I am experiencing several BSOD errors (named above) a day. Sometimes other errors appear, microsoft seems to be quite creative in giving error names.

The problem can appear anytime, and always when I shut down my computer, or when I put it in sleep-mode.

I have started my laptop in safemode with internet and without internet connection. When restarted in normal mode after having had it in safe mode without internet connection, windows does not want to report an error. Therefore I am guessing it has something to do with a driver related to my wireless / or a program dependent on the internet connection.

Here is my dumpfile.

Thanks alot for your help!

I recently have been having constant BSODs within the past month or so that at first seemed graphics related. I am not sure what the problem is but any assistance would be greatly appreciated.

OS: Windows 7 Ultimate x64 SP1
CPU: AMD Phenom II x4 965 Deneb @ 3.4 GHz
RAM: 8GB G.Skill Ripjaw Series DDR3 1600 (4x2GB) **Originally 4GB See Below
VID: Sapphire RADEON HD 6850 1GB
HDD: 300 GB Hitachi SATA (Primary) / 1.5 TB WD Sata (Secondary)
PSU: Thermaltake Toughpower 700W PSU

Originally I had thought this to be a graphics card issue because I had a prior GeForce GTX 280 die on me. It was replaced by a GeForce GTX 460 Superclocked and I was still experiencing BSODs.

After that I ran Memtest to test my ram and it came back with no errors. I only ran the test for a few hours so I am wondering if I did not test thoroughly. I ended up purchasing another 4GB and just replacing the original RAM. The machine still continued to blue screen so I figured it wasn't a memory problem and installed the original 4GB of RAM.

I am still continuing to receive 0x1A (Memory Management) and Bad Pool Header errors. Any help that I could get would be greatly appreciated.

A:Recent BSOD errors (Memory Management/Bad Pool Header)

Typical Memtest86+ runs should be done with at least 7 consecutive passes.

Nothing here is conclusive so far. I recommend you start Driver Verifier to see if it's driver related.

So far my biggest suspicion is hardware. One of the crashes mentioned code corruption where one solitary bit was lost. Often memory failure is not the cause of solitary bit problems, but they still have the potential to do so, in which case you'll want to run Memtest more. Usually, however, this is caused by either a failing Motherboard, CPU or PSU, or one of the components are overheating.

You can check with overheating using HWInfo with Sensors only enabled. Log two 30 minute sessions: one for idle, and one for high load (gaming, benchmarks, etc.). Send to use for viewing.

Hi. I've always had issues with removable storage on this Desktop - Dell Dimension 4600 Windows XP Home SP3. Never much of a problem until I installed the new version of Avira Free. I've already addressed this issue on their forum, but received no helpful response. But the new version starts, stops, and restarts the service several times during a scan. And if I have a flash drive plugged in, I receive Removable Storage Service errors. Not sure of the particular ones, because I've since uninstalled Avira 10 and using 9 instead. However, I've noticed when I go to Computer Management in the Control Panel and then to Removable Storage, I get the same errors. And then I have to manually unplug the flash drive and reinsert it, because I can't access the drive until I do, and Safely Remove won't work. Same thing happened when I used Avira. And with Avira, it also occurred on our laptop. Haven't seen if it occurs when just accessing Removable Storage.

I mentioned I've had problems with Removable Storage before. Basically, if I have our printer on while running our nightly backup, I receive disk errors and warnings on the flash drive - something about a paging error. And when we have another flash drive in the other port and print something, that disk gets errors. We use two USB ports on the front of the tower. I've tried uninstalling the flash drives and plugging them back in to reinstall the drivers. But since it doesn't really cause any noticeable problem, it's not too important... Read more

Hello! I was recently playing a game on my computer when it suddenly crashed. After several attempts to restart, it eventually succeeded, but immediately swarmed me with error message pop ups. My computer cannot detect the local network, but all external hardware have been confirmed operational (been using my phone on its wifi for the past 6 hours). Additionally, whenever I try to access my device manager, I get an error telling me there is insufficient storage to perform the operation. My SSD has 3.8 GB of free space at the moment (has been below that for most of its use), and my computer still lists itself as having 8GB of RAM. I've tried accessing my device manager and network manager on my admin account, the hidden admin account, and in safe mode with the same problems occurring every time. I've run an SFC scan which has detected corrupt files without being able to repair them. I've pasted the log below in hopes that someone can interpret the information and tell me what I need to do to fix my computer. Any help or advice would be appreciated.

I was asked by answers.Microsoft.com to refer this question to this forum.

BTW there doesn't seem to be an option for Windows 10 forum. So I  had to choose Windows 8.

1st of all everything was fine until 2nd of December.

My Laptop installation of Winodw 7 and then upgraded to 10 was configured from the start to have the USER folders (u sing a script provided by Microsoft) on an SD card through an Expresscared media read/write because my system disk is a 64gig SSD
( which BTW means that system restore has been disabled).

on 3rd of December when:

I turned the machine on it couldn'the read my user profile.I tried to login in safe mode but I got sihost warning: unknown hard Error! But I got into prompt screen and ran diskpartThere is an inbuilt SD card reader slot in the machine where I store large downloadBut the system could only see the main SSD and the expresscared SD card with user folders on itI ran sfc /scannow &  then DISM and the sfc /scannow again until both were successful.But again diskpart  only detected the SSD and Expresscard SD cardBut the attributes on the SD card claims that Current state read-only : Yes although read-only flag is No.I have checked the SD card on other machines and it is not write protectedI have tried introducing writeprotected entry in the registry with values of 0 and 1 without successI have tried everything else that I could in Safe mode but other than what is expected in safemode (e...

DIY desktop computer used as test box. Both production (build 10586) and development (build 14322) installed.

I use storage spaces (two 1TB drives pooled in two-way mirror, ReFS formatted) with build 10586 for backups and archives.

Whenever I restart into build 14332 the storage spaces drives show constant disk activity and Storage Spaces does not appear in the This PC window in build 14332. When I return to build 10586 I again have a lengthy period of disk activity once more. However the Storage Spaces does appear in the This PC window in build 10586 as expected and I can access the space just fine. I get messages that Storage Spaces needs attention and when I access the Storage Spaces window via the Control Panel the drive statuses show that repair is under way. After a few minutes the drive statuses change to OK. However, the status bar at the top of the Storage Spaces area remains orange and I have a warning message. This status persists over restarts of build 10586.

Question 1: Since the physical drives section shows that the devices are OK, where can I check further for the exact problem?

Question 2: How can I clear the warning message if in fact ReFS has fixed itself?

Question 3: Is there a method to preventing this the next time I boot into a preview build short of turning off or physically disconnecting the pooled drives?

I have posted feedback, although I mistakenly left the type as "suggestion."

Here is the disk management panel (... Read more

I need help very bad and I read a post that JCGRIFF posted to help an individual out on but that was awhile ago! I need that type of help if someone can help.

Good day all, I hope someone can help me with a consistent BSOD problem I've had today.

Every time my Steam client starts up and attempts to download its latest update, I get a BSOD with a Bad Pool Caller (one time out of about a dozen crashes it was Bad Pool Header instead). I have tried the Steam support, but their guides are focused on the program crashing, not the whole computer and I have had no luck fixing it there.

I downloaded DM Log Collector and attached my report, but I want to point out now that Windows has not produced dmp files for any of these crashes, even though the correct options are checked in the "Startup and Recovery" settings.

Thank you kindly for any help you can offer.

PS - I'm headed to bed, I'll be back tomorrow around 7am EDT.

A:BSOD on Steam Update, Bad Pool Caller or Bad Pool Header, no dmp files

Make sure your dump logging is enabled.

Click Start, point to Settings, and then click Control Panel.
Double-click System.
Click the Advanced tab, and then click Settings under Startup and Recovery.
Check Write an even to the system log, and Automatically restart.
In the Write debugging information list, click Small memory dump (256k).

Hello i would like to know why im crashing so often, literally i crash 4 or 5 times daily at random times, and i keep getting those BSOD's, but all this started when i updated to Win10 (I knew that updating at day 0 was a bad idea z.z )
I will leave the minidumps attached so you can analyze and hopefully tell me what is failing, but i already suspect a driver failing because no win10 support.

Apparently you need to tell Windows that you want to use the machine as a file server and that it should allocate resources accordingly.  Set the following registry key to ‘1′:

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache
and set the following registry key to ‘3′:
After making these changes and restarting, I haven’t seen this issue arise again

Hello i have a computer with win7 32 bit .And it started responding very slowly after an year or so.
So i decided to move onto Win8 64 bit.but after downloading i realized that win 8 64bit setup couldnt run on win 7 32 bit.So i decided to do a clean install from a flash drive of 16 gb.So when i started my computer and tried to boot into the flash drive it got stuck at the message "Verifying DMI Pool Data".I left it there for an hour but still no progress.

Please help me out of this situation .
Any help would be appreciated

A:Windows 8.1 installation stuck at verifying DMI Pool Data on Windows 7

Win8 is not an upgrade, but a quirky phone app pretending to be an OS. You'd be better off working through the Troubleshooting Steps for Windows 7 to resolve the problems with 7 which always runs perfectly if it is installed and maintained correctly.

Format the flash stick using Option One of UEFI Bootable USB Flash Drive - Create in Windows

Then boot the stick as a UEFI device in BIOS Boot Menu to install as UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums

If problems persist test your hardware from Troubleshooting Steps for Windows 7.

You can also set to Legacy, CSM with Legacy Boot first in BIOS setup, then install WIn7 normally to an MBR drive. In either case you should delete all partitions during the booted install.

A:Bad pool caller on windows 8

Wow! That's a lot of memory dumps!

Please provide this information so we can provide a complete analysis: Blue Screen of Death (BSOD) Posting Instructions

Unusual set of dumps:
- many different BSOD error codes. Usually indicative of a low-level/hardware problem
- each one blames ewusbwwan.sys - a driver component of your Huawei 3g modem

I'd suggest first replacing the Huawei 3g modem drivers with a freshly downloaded set of the latest, Win8 compatible drivers. First un-install the one's that are on the system - then install the freshly downloaded one's.

Please update these older drivers. Links are included to assist in looking up the source of the drivers. If unable to find an update, please remove (un-install) the program responsible for that driver. DO NOT manually delete/rename the driver as it may make the system unbootable! :
