As far as i know Windows takes the spanned volume as a full logical volume, and writes along it so that data falls whatever it wants to. What i'm asking is if windows allows for single disk jbod, writing each file independently on each disk and keeping a more or less level of occupation on each disk. Thanks.

When you have disks on a hardware RAID controller that are not in a RAID configuration you have JBOD which are no different that what you normally have in a computer. You would learn much more about all this if you would take the time to do some research on your own! You are asking a BUNCH of questions that you could find the answers to on your own if you took the initative to do some research and educate yourself! Spanned Volumes A spanned volume consists of disk space from more than one physical disk. You can add more space to a spanned volume by extending it at any time. To create a spanned volume, perform the following steps: Open Disk Management. Right-click the unallocated space on one of the Dynamic disks where you want to create the spanned volume and then click New Volume. Using the New Volume Wizard, click Next, click Spanned, and then follow the instructions on your screen. Here are guidelines for spanned volumes: You can create spanned volumes on Dynamic disks only. You need at least two Dynamic disks to create a spanned volume. You can extend a spanned volume onto a maximum of 32 Dynamic disks. Spanned volumes cannot be striped. Spanned volumes are not fault-tolerant. Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

How could a single disk be JBOD (Just a Bunch Of Disks)? The definition of bunch is more than one. So a single disk cannot be a bunch! LVM can be used to creat Dynamic Disks which allows you to span across more than one disk, but I'm don't think it is the same as a JBOD. And, LVM can be used to create a software RAID 1, but I don't think you can mix the two. Why don't you do some research on the internet and find forums that are intended to discuss your ideas?Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Thanks for your answer. I must note that we haven't understood each other, but it also seems this isn't the appropiate forum to discuss this issues as you earlier suggested. -------------------------------------------------------------- Relating to the JBOD + Raid 1. I don't know where to post this, so please if this is not the correct form/forum please tell me where to do it: I've been searching on a JBOD + RAID 1 and i've found nothing, so i'll explain how to do it. You have to actually lie to your OS, as you will be using two RAID software, windows and another (built-in to your motherboard - most motherboards nowadays have it in form of Nvidia MediaShield or Intel Matrix Storage). First you tell your motherboard to create a JBOD volume with all the physical drives that will use it (i wanted to use part of a physical drive to be windows boot partition, but you can't do the other way). Now, if windows doesn't have the motherboard driver installed - also called fakeraid - (which actually is who does the software raid) it will still recognize the drives as independent. You MUST install the driver to continue. Once Windows recognizes the drives as a single one, you can create a mirrored from the jbod and from your other storage medium. (Note: this can be done using dynamic discs, as windows will lovely threat them).

Well, because i intend to use windows built-in software. And as far as i know these are the official Windows 7 support forums. If i don't get the answer i'm looking for here i'll go to the server forums as you said :). When i said single disk jbod i meant that each file is stored on a single disk, so that it won't be split among various disk as does when you use a single logical volume.
