• Create Software Raid 5 Windows 10

I have always had a hardware RAID 5, but recently lost tons of data due to a drive loss, even after recovery steps. I am trying to set up a RAID 1 on 3 drives, and I.

I have had a win7 Ultimate 64bt running on a Dell XPS 420 with 4 drives. Disk 0 is a 300GB containing the OS. Disks 1,2,3 are 2TB seagate drives that I had installed and opted to create a RAID 5 volume. One of the disks failed, it was easy to identify as it was making a loud clicking noise. I removed the drive and got a replacement. When I installed the drive, as you can see in the picture, the bad disk 3, went to disk 4 and the new drive is now Disk 3. My question is how to get the new disk 3 to replace the old one disk 4 that is 'missing'.

I have looked far for information on using Raid5 on a Windows 7 Ultimate OS and have not been able to find any information. Also, will my data will be restored? I also used carbonite to backup all the important data but it would be nice to get the unimportant data back as well. Any help would be greatly appreciated.

Unlike in RAID 4, parity information is distributed among the drives. It requires that all drives but one be present to operate. Upon failure of a single drive, subsequent reads can be calculated from the distributed parity such that no data is lost. RAID 5 requires at least three disks. RAID 5 is seriously affected by the general trends regarding array rebuild time and the chance of drive failure during rebuild. Rebuilding an array requires reading all data from all disks, opening a chance for a second drive failure and the loss of entire array. In August 2012, Dell posted an advisory against the use of RAID 5 in any configuration and RAID 50 with 'Class 2 7200 RPM drives of 1 TB and higher capacity' for business-critical data.

After confirming with our product team, it says that RAID-5 is only supported on computers running Windows 2000 Server, Windows 2000 Advanced Server, Windows 2000 Datacenter Server, Windows Server 2003 or Windows Server 2008 Operating Systems. In Windows 7, only hardware-based RAID is supported. Thus I recommend that you check your computer to see if it meets this requirement and visit the motherboard’s support web site to download the RAID drive controller drivers.

It appears that simply adding your replacement disk didn't trigger an automatic rebuild of the array.

All you should have to do is go into the controller and add the new disk to the array manually, the array will rebuild, and in a few hours Windows will detect the array properly. As for your data, it's probably still intact. Just get the array back to healthy status and Windows should automatically detect the array. Hi Jeff, From this screenshot, we could see the failed volume number is 0. The disk you want to use to replace the bad one is seems disk 1. (it's different with the original screenshot you provided).

Next, make sure these number is not mess. And then run these commands: select volume 0 repair disk=1 Finish the process, run list volume again to check the result.

I just created a new software RAID-5 volume in the disk manager, but before it was done with the initial resynch, I had to reboot. When the server came back online, the status was 'resynching,' so I assumed that everything was going well, and if I watched it long enough that the percent completed would appear there, too. I left it overnight and it still just says 'resynching.' I discovered that 'Reactivate volume' was a valid option in the context menu, so I tried that, and the cursor flashed a few times and '4%' briefly flashed in the status field before disappearing. It still just says 'resynching,' and 'reactivate volume' is still valid in the context menu. I'm not sure what's going on, and there doesn't seem to be anything in the system event log.

Firstly, if it's a hardware issue, then wouldn't there be something in the event log? When a disk fails, or a controller stops responding, there is definitely an event. There is no warning icon next to any of the drives indicating a bad block or anything like that. Secondly, there is no hardware vendor to contact because I built this server. The drives all test OK, and the controller tests OK, so contacting those vendors won't get me anywhere. Yes, I know the initial sync can take a long time, but as soon as the OS is able to reasonably estimate how long it will take, it posts a% completion in the status field.

After being left along for 14 hours, it did not post a% completion. If it is a hardware based RAID, you won’t see any error messages in the event log. I wasn’t talking about the server. You should contact RAID controller or hard drive manufacturer. They can provide with to some vendor specific diagnostic tools. Are you using the latest BIOS on the RAID controllers?
