I have an array I used with Win Server , and want to continue using it for my personal data. I have a machine designed for virtualization working with win 7 ultimate as a parent OS at this time. I cannot find a hardware host controller to install into my system to provide an external esata connection to the array. You may well contact LSI or Adaptec directly or find a more appropriate forum to find the actual capabilities of these types of SAS controllers Office Office Exchange Server.
Not an IT pro? Windows Client. Sign in. United States English. Ask a question. Now I realized the question was also about Windows 7 - you should not use Win7 for anything anymore let alone dream about raid arrays.
If you want a low cost storage server use linux instead. DeaconFrost [H]F Junkie. Joined Sep 6, Messages 11, DeaconFrost said:.
Far be it from me to agree with him, but software RAID is not very portable. It does require drivers If you try taking a software RAID array to another computer, there's a very good chance it will not be accessible.
If you try to move a hardware array, it works perfectly. There's an old saying us old-timers have heard millions of times. Never let software do the job of hardware. No, there are no drivers. Software RAID is very portable as it specifically does not require any drivers. What do you think mdadm or ZFS are?
Windows is no different. I'm definitely not confusing the two. If you mix the order of the drives, swap architecture, etc, you can easily lead to a failed "array". Been there, done that enough to know it isn't very portable. It's no where near as flexible and portable as moving a RAID controller card to another system, powering up, and seeing your data.
With all the windows updates and things getting messed I wouldn't trust a software raid inside Windows further than I can throw it. It's a recipe for problems more than anything else, especially if you do raid0. A true hardware raid is completely transparent to Windows and cannot be broken by any windows update. And what happens when you RAID controller dies and you cannot find the same or someone that is compatible with?
I think the answer is obvious, but I have no experience in this to back it up. This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread. I have the same question 0. Report abuse. Details required :.
Cancel Submit. Are you using software or hardware RAID? Microsoft expects that most future systems will have this support. Customers should consult with their system vendor to determine the ability of their systems to support UEFI and disks that have storage capacities that are greater than 2 TB. For a system to be able to address the maximum capacity of a device that has a storage capacity of more than 2 TB, the following prerequisites apply:.
The Windows version must be one of the following bit or bit, unless otherwise noted, but including all SKU editions :. The latest storage drivers from your storage controller manufacturer must be installed. For example, if your system uses an Intel storage controller that is set to "RAID" mode, make sure that you have the latest applicable drivers from the Intel support site. Overall, you should contact your system vendor to determine whether the system supports device sizes of more than 2 TB.
For example, if your system uses an Intel storage controller set to RAID mode, make sure that you have the latest applicable drivers from the Intel support site. Consult your system vendor to determine whether the system supports both UEFI and the startup of devices that have storage capacities of greater than 2 TB. The following tables list Microsoft support for the various concepts that are discussed in this article.
This information provides an overall support statement about disks that have a storage capacity of greater than 2 TB. Hybrid-MBR is an alternative style of partitioning that isn't supported by any version of Windows. However, the remaining capacity cannot be addressed and, therefore, cannot be used. The following steps show how to initialize a fresh disk by using the GPT partitioning scheme to help ensure that Windows can address the maximum available storage capacity.
Make sure that you back up any important data before you try these steps. Click Start , type diskmgmt. If it's necessary, enter the credentials for a user account that has Administrator privileges. When a non-initialized disk is detected by Windows, the following window opens to prompt you to initialize the disk. If you select this option, this hard disk will not be recognized by Windows versions earlier than and including Windows XP.
Check the Disk Management window to verify that the disk is initialized. If it is, the status row for that disk at the bottom of the window should indicate that the disk is Online. After the disk is initialized, you must create a partition, and then format that partition by using a file system.
