RAID 0 Data Recovery
RAID 0 data recovery is something we do on a daily basis. This type of array is used by home users and small businesses. Also known as a striped set, RAID 0 splits data evenly across two or more disks with no parity information for redundancy (see article HERE). We can recover data from these striped sets. Regardless of the problem, if you have suffered a drive failure, controller failure, or file system corruption, we can recover data from your RAID 0 array.

Many customers are utilizing this technology and they don’t even realize it. RAID 0 is commonly used in 500GB+ external drives. Some of the most common of these that we get in are LaCie Big Disk, Buffalo Technology drives, Maxtor One Touch drives, and some Western Digital MyBook drives. It should be noted that for any RAID 0 data recovery to be successful, ALL drives must be accessible. If one drive has physically failed, then we must first get that drive functional again so that we can image and destripe the set. If we cannot image all of the drives within the array then data corruption will be prevalent.
Guaranteed RAID 0 Data Recovery
RAID 0 data recovery is not as complex as other RAID types, but it does present it’s fair share of challenges. Depending on the configuration, recovering data from a RAID 0 array can be a time consuming processes. This is especially true when dealing with 6 or more drives in the array. When we perform RAID 0 data recovery, we start off by analyzing all of the hard drives, making any necessary repairs, and then imaging each hard drive sector-by-sector. That way we are working from a carbon copy of the original hard drive when we go to rebuild the array. We give our customers a 100% satisfaction guarantee on all RAID 0 data recovery work. We never charge an evaluation fee, and there is no charge if the data is unrecoverable. We’ll even provide you with a prepaid shipping label when you send in your drive for recovery. So you are risking absolutely nothing to let us help you.
Notation About RAID 0
It is important to note that RAID 0 was not one of the original RAID levels, and is not redundant. RAID 0 is normally used to increase performance, although it can also be used as a way to create a small number of large virtual disks out of a large number of small physical ones. A RAID 0 can be created with disks of differing sizes, but the storage space added to the array by each disk is limited to the size of the smallest disk—for example, if a 120 GB disk is striped together with a 100 GB disk, the size of the array will be 200 GB. Although RAID 0 was not specified in the original RAID paper, an idealized implementation of RAID 0 would split I/O operations into equal-sized blocks and spread them evenly across two disks. RAID 0 implementations with more than two disks are also possible, however the reliability of a given RAID 0 set is equal to the average reliability of each disk divided by the number of disks in the set. That is, reliability (as measured by mean time to failure (MTTF) or mean time between failures (MTBF)) is roughly inversely proportional to the number of members—so a set of two disks is roughly half as reliable as a single disk. The reason for this is that the file system is distributed across all disks. When a drive fails the file system cannot cope with such a large loss of data and coherency since the data is “striped” across all drives.
