Q. What file systems are supported under RAID Reconstructor?

A. RAID Reconstructor can reconstruct any file system provided the array is not of a proprietary order and the start sectors are the same across all the drives in the array.

Q. How do I enter my drives into RAID Reconstructor?

A. There are two ways. The first is to right click on the white space to the right of the drive number, you will have a drop down list to choose from. The second way is to click the three periods at the end of the white place and the same drop down list will appear.

Top


Q. My physical drives are not showing in the list, why?

A. There are two reasons why this can happen. If you are running Windows Vista or above, you need to close RAID Reconstructor and reopen it by right clicking on the RAID Reconstructor icon and choosing "Run As Administrator." The second reason is that the drives are still attached to the RAID controller which hides the physical drives from Windows. Attach the drives to a non-raid controller and you shoudl then see them in the list.

Q. I am missing a drive from my RAID 5 array, can RAID Reconstructor work without this drive?

A. Yes. If you have 4 drives, tell RAID Reconstructor that you have 4 drive and enter the three good drive while leaving one of the drive numbers empty. The software will rebuild the missing drive from the XOR data of the other three drives. This is the same regardless of how many drives you have.

Top


Q. I am missing a drive from my RAID 0 array, can RAID Reconstructor work without this drive?

A. Unfortunately, the nature of a RAID 0 does not allow for the loss of a drive in the array. There is not a way to recover this array with software.

Top


Q. I am missing two drives from my RAID 5, what can I do now?

A. A RAID 5 can only be recovered with the loss of one drive. If you have lost two drives, there is not a way to recover this array with software.

Top


Q. Under the Tools menu, what is the XOR test?

A. The XOR test verifies the checksum over a drive set and visually shows you the XOR of the drives in the set. Check the help file for detailed instructions.

Top


Q. Under the Tools menu, what is the entropy test?

A. The entropy test allows you to visually see how the array is put together. This can help to determine if a drive is missing or damaged.

Top


Q. What do I do with the block size, start sector, and rotation options on the main screen?

A. If you do not know these settings, do not touch these options. The software will determine and set these parameters automatically during the analysis.

Top


Q. Why can't I analyze when I have more than 11 drives when the software allows me to input 14 drives?

A. The analyze phase with 11 drives can take a few days due to the number of combinations where the block size, rotation, and start sector are concerned. 12 drives would take almost 7 years to analyze due to the exponential increase in the number of drives. If you know the exact parameters for the array, you can enter them into the main screen and skip to step 3. If you do not know the exact parameters, we can determine the parameters in less than 24 hours with our RaidProbe Service.

Top


Q. What does "Run the Differential Entropy pre-test and review the settings" mean?

A. The differential Entropy test will try to determine the best starting sector, and block size of the array. Once it determines them, it shows a preview of the settings to you, to allow you to make any changes, before it analyzes the data. This is the best solution if you are unaware of the parameters of your array.

Top


Q. What does "Review the settings" mean?

A. This allows you to manually pick your starting sector, block size, sectors to probe, and rotation. This is useful if you have an idea of what the block size, rotation or what the start sector is and will speed up the analysis by excluding the ones you know are incorrect.

Top


Q. What does "Just go" mean?

A. When you choose Just go, it runs the Differential Entropy pre-test and starts the analysis without the preview. You do not have the option to change any settings when choosing this option.

Top


Q. After the analysis, I get a message that says "This result is not significant", what does this mean?

A. This means the software did not find the proper parameters for your array. There are many reasons this could happen. If you have excessive file system damage, if your array is using a proprietary order or rotation, if the start sectors on the drives are different, and many more. In a case like this, we recommend using our RaidProbe Service and let us determine all the parameters for your array.

Top


Q. What do I do after I get a recommendation?

A. This means the software has identified the correct parameters for you array. You should click finish and proceed to step 3.

Top


Q. What if I get sector read errors during the scan?

A. Look at the message and it will tell you what drive the error occurred on. If it is a RAID 5, remove that drive from the drive listing in step 1 and run the analysis again. If you get more sector read errors, make images of the drives as soon as possible and then proceed using the images. If it is a RAID 0, make images of the drive and use the images instead of the physical drives.

Top


Q. Can I investigate the quality of my files before I buy the software?

A. No. RAID Reconstructor does not look at the array on a file level, so there is not a way to do this. The scope of the software is to determine the parameters of the array only. By getting a recommendation in step 2, you know that you are getting the correct parameters of the array and provided there is no major file system damage, you should be able to recover the data from the reconstructed array.

Top


Q. Why can't I select copy in step 3?

A. You must purchase the software before you have the ability to output the recovery with any of the options in step 3. Once you enter your key, you will have the ability to save your output.

Top


Q. What is a virtual image?

A. A virtual image is an XML document that tells our other software (DiskExplorer, GetDataBack, and Captain Nemo) how the array is put together and pulls the data directly from the physical media. This prevents you from having to output an image that is the full size of the array or writing the data to a new drive before recovering the data.

Top


Q. What does the virtual image selection do?

A. It outputs a small file (less than 3kb in most cases) that will allow you to recover the data using our other software (DiskExplorer, GetDataBack, and Captain Nemo) without the need for a full image or the data being written to a new drive first.

Top


Q. What does the image selection do?

A. This outputs a raw image file that is the same size of the array. For example, if the array is 600GB, this will output a 600GB file, regardless of how much data is on the array. This is useful if you have a different recovery software you wish to use.

Top


Q. What does the physical drive selection do?

A. This allows you to write the data back to a new drive directly. This is useful if you only have a controller failure, you can write the data to a new drive, reboot and have full access to the data. You may even be able to put the drive back in the machine the array was on and boot from it. This will destroy any data on the drive, so be careful when using this feature.

Top


Q. What do the links in step 4 do?

A. Once the Virtual Image/Image is made, these links open the image in the application link you choose. For example, if you have a virtual image and you click the Captain Nemo link and you have Captain Nemo installed, Captain Nemo will launch and the image will mount itself up and present the data to you (provided there is not any file system damage preventing Captain Nemo from mounting the image). If the application you choose is not installed, you will be presented with a link to download the software first.

Top


Q. Why do I get the message that the file does not exists when I click a link?

A. The only time you will get this message is when you have the software installed for the link you clicked but you have not created the output file in step 3. Create the Virtual Image/Image and then click this link.

Top


Q. What image types are supported in RAID Reconstructor?

A. Any single file RAW image will work, unless it is created by our software, then a multi-file image can be used. You can not use an encase image, however you can output that encase image to a single file DD image and use that in RAID Reconstructor.

Top


Q. How do I create an image in your software?

A. You can create an image in either GetDataBack, Captain Nemo, or DiskExplorer. Each has its own way to create an image so check the help file in each of them. They all produce the same type of image file. Do not use DriveImage XML as that is not a compatible image for data recovery.

Top


Q. Why can't I choose RAID 1 in the software?

A. A RAID 1 is two or more drives that are exactly the same data duplicated across the RAID 1. You can simply take one of the drives and scan it in GetDataBack to recover the data.

Top


Q. Why can't I choose RAID 10 (1+0) in the software?

A. A RAID 10 (1+0) is two RAID 0's put together. You need to determine which drives belong to each side of the RAID 0 and then use RAID Reconstructor to analyze the RAID 0. If you can not determine the correct drives on each side, you should use our RaidProbe Service and let us take care of it for you.

Top


Q. My RAID is my boot drive, how do I run RAID reconstructor now?

A. You need to move the drives into a working machine as slave drives or you can use a bootable CD with our software on it to get access to the drives. The drives need to be attached to a non-raid controller for this to work. You can find all the details about creating a bootable CD here.

Top


Q. What about support for RAID 5E/5EE/RAID 6?

A. These types of arrays can only be recovered currently using our RaidProbe Service.

Top


Q. I have my virtual image/image, how do I decide which product to use for recovery?

A. If possible, you should always use Captain Nemo as it is faster and more efficient than using GetDataBack. If you have file system damage and the image does not mount in Captain Nemo, then you should use GetDataBack at that point.

Top


Q. Other than speed, why shouldn't I use USB drives?

A. USB does not support error checking, therefore the data that RAID Reconstructor is using could be unusable and corrupt your recovery. Do not use USB drives for data recovery purposes. Remove the drive from the external case and install it internally.

Top


Q. Is there a way to add user defined parity schemes to RAID Reconstructor?

A. There is not a way to add your own parity schemes. You can use our RaidProbe service and we can determine the parameters for you.

Top


Q. How do I recover a Network Attached Storage (NAS) RAID?

A. A NAS usually is a Linux software RAID. You need to find the start of the RAID partition, usually the last and biggest partition. Run the analysis from there. A more convenient way is our new software NAS Data Recovery that does all the work for you.

Q. Isn't there an easier software for the recovery of a simple Windows RAID?

A. Yes, try our fully automated RAID Recovery for Windows.
