RAID 0 + 1 Data Recovery Service from True Industry Experts

Your business might use a Redundant Array of Inexpensive Disks (RAID) to store data across multiple drives for increased security. RAID links two or more disks to create a storage device with high capacity, low cost and efficient performance. RAID 0 + 1 is one such system. Business owners and individuals often believe if they have a RAID, their data are secure because they are reproduced in more than one location. However, all RAID systems are vulnerable to failure and sometimes need the services of a data recovery professional.


RAID 0 + 1

RAID systems use a variety of techniques to transfer data to disks. With striping, data maps across physical drives in sequence across the array. Mirroring creates an exact duplicate on corresponding drives, so it takes up twice as much space.

RAID 0 + 1 is sometimes referred to as a mirror of stripes. It typically needs at least four disks. When data transfers, disks inside groups are striped, but groups mirror each other. RAID 0 + 1 has similar performance and storage capacity to RAID 10, but lower fault tolerance.

Signs of Drive Failure

RAID 0 + 1 can fail for a number of reasons. When a system is used around the clock for years, components eventually wear out. Sometimes employees drop or jar equipment and the impact causes internal damage. Power surges and storms can create internal damage. Electronics generate heat, and poor ventilation can cause them to wear out faster than expected. Viruses, worms or malware can damage directory structures, files and registries.

If you notice any of the following from your RAID system, shut it down and contact an expert:

  • Clicking sounds that signal hard drive damage
  • Error messages that state your computer cannot find the operating system
  • At startup, your computer cannot find the hard drive
  • File access is extremely slow, signaling potential data corruption
  • An inserted USB drive cannot be recognized

Why You Shouldn’t Attempt Recovery Yourself

Most of the time, data can still be retrieved when systems fail. Permanent data loss occurs when users try to fix a problem using incorrect methods.

Users sometimes search online and find downloadable software or free tools, but for most organizations those solutions just make things worse. RAID is made of several disks that work in groups, saving data in multiple locations according to a set of rules specific to each system. Installing the wrong software or attempting recovery could permanently overwrite the mission-critical data you’re trying to save.

If you experience system failure, Flashback Data offers a no-data, no-fee guarantee. We’ll evaluate your media at no cost, so if the price is more than you are comfortable with or your data is completely lost, it won’t cost you a thing. When you mail it to us or drop it off at one of our locations, we’ll give you a firm quote and wait for approval before we proceed with repairs. Get your data back on your timetable and stay updated every step of the way. Contact one of our experts to find out more.



It depends on the RAID level and your knowledge of the system. If it is a complicated setup that you are unfamiliar with or feel uncomfortable at all, contact a data recovery RAID professional immediately, especially where critical information is involved. In the event of a single hard drive failure in a redundant RAID type where the data is still accessible, replace the failed drive with an exact spare and let it rebuild the array. If you have a second failure, or you have hot spares set up and you are unsure of the order of the drives, you will only make matters much worse or even unrecoverable if you try to replace or rebuild drives. Whatever you do, do not reinitialize your system if you are concerned for you data.

We have seen countless situations where staff that is not completely familiar with their systems, try to ‘fix’ the problem but only make it impossible to perform a RAID data recovery. In most of these situations, it would have been possible if they contacted a data recovery professional before trying to reinitialize.
