Recovering RAID Arrays with Diskinternals Raid Recovery

With so many motherboards these days coming with built-in RAID controllers, the demand for disk tools to support native RAID arrays is there, but so far it is rarely met by software manufacturers. Diskinternals Raid Recovery is among the first few products to feature dedicated low-level support for the various types of RAID arrays. How does this data recovery tool fare against its single-disk competitors? Read our Diskinternals Raid Recovery review to find out!

Dedicated, Native and Software RAID Arrays

RAID arrays are a cheap and easy way to get bigger, faster or more reliable storage out of existing hard drives. Connect several hard drives into a striped array (RAID-0) and get a performance increase and a bigger storage at the same time at a cost of reliability. Mirror several disks into RAID-1 and get bullet-proof storage but sacrifice capacity for reliability. Form a RAID 1+0 (or RAID-10) array to get benefits of mirroring and striping at the same time, and receive performance gain and reliability by using three or more disks. Or use striping with error control to form a RAID-5 array that balances performance with reliability.

In theory, RAID looks bright and handy. But what happens of one of the disks breaks? Even worse, what if you were using a RAID controller built into your motherboard, and that motherboard failed?

RAID-Specific Data Recovery

If you used a mirrored array (RAID-1), just swap the faulty disk for a new one, or continue using the remaining disk(s) as usual. Simple? Sure. But how many people are using mirroring? By using RAID-1, one is losing storage capacities of all disks in the mirror except the first one. There are no performance benefits either. RAID-1 is strictly for reliability, and as such it is not widely popular at home or small offices.

If you used any other kind of RAID, you may be in trouble. RAID-0 does not have any built-in data recovery capabilities at all, while RAID-5 and 0+1 can tolerate a failure of a single disk. Attempting to recover data from these arrays with data recovery tools designed to work with single disks will cause severe damage to the contents of the disks, and will make any future recovery attempts difficult or impossible.

If you used a native RAID controller on a computer motherboard, you’re in trouble. Your only options are either replacing the motherboard with exactly the same model (or a model with a compatible RAID controller from the same manufacturer), or somehow trying to retrieve data from the broken RAID array.

Diskinternals Raid Recovery

Diskinternals Raid Recovery comes handy when you have a corrupted or dismounted RAID array, or simply have an ordinary case of logical data corruption that can happen whether or not you used a RAID or a single disk.

Diskinternals Raid Recovery: Operation

Diskinternals Raid Recovery re-assembles and recovers data from corrupted RAID arrays completely automatically. It is the first tool in our review lab to automatically detect the type of the RAID array, including the manufacturer of the RAID controller that was used to create the array. Importantly, Diskinternals Raid Recovery is able to recover data from corrupted RAID arrays whether or not the disks of the former array are connected to a compatible RAID controller or not. Therefore, you can easily plug your disks into a PC with no RAID controller, run Diskinternals Raid Recovery, and see it recover your files and data.

Diskinternals Raid Recovery is designed to be easy to operate, and indeed, we had no trouble running the program and using it to scan a dismounted RAID array on our test PC. The product operates as advertised, which says a lot about such complicated product. The interface is friendly, and not much different from Windows Explorer. Its operation is very similar to Diskinternals Partition Recovery that we reviewed earlier, except that it gives you an ability to control parameters specific to RAID arrays.

Watching Diskinternals Raid Recovery re-construct an array is amazing. You can simply drag and drop separate disks to form an array, and see how the array is being automatically detected with your original disks and partitions stored on that array becoming visible. Amazing stuff!

Featuring advanced data recovery technologies that are familiar from other DiskInternals products, Diskinternals Raid Recovery supports PowerSearch, BootCD, FTP Export, and Live Preview technologies. Click the links above to read our detailed reviews about these features.

Conclusion

There is not much choice of data recovery tools to support RAID arrays, and almost none of them support motherboard-based Native RAID. Diskinternals Raid Recovery is a pleasant surprise here. It was easy to operate, and worked exactly as advertised.

Diskinternals Raid Recovery works whether or not the disks are connected to a compatible RAID controller, allowing you to simply connect your ex-array to any compatible IDE or SATA ports in any computer. Supporting RAID 0, 1, JBOD, RAID 5, and 0+1 arrays, working with arrays created with dedicated RAID hardware and RAID-enabled motherboards manufactured by Intel, NVidia, and VIA, and supporting software-based RAID by Microsoft, also called Dynamic Disks, Diskinternals Raid Recovery is a truly universal RAID recovery tool that is well worth its price. Highly advanced technologically, Diskinternals Raid Recovery truly deserves our Editor’s Choice Award.
