Introduction

A redundant array of independent disks (RAID) is designed to introduce fault tolerance and/or faster performance for your data storage. While RAID volumes offer a number of advantages during normal operations, they are significantly more complex to implement and even more complicated to service in the case of catastrophic failure. RAID retrieval, in most cases, is something that should only be attempted by a well-trained data recovery professional. However, there are a few cases where basic RAID retrieval procedures are within the capabilities of an intermediate level technician with a working knowledge of RAID volumes and a professional-level  data recovery toolset. This website is designed to orient the in-house IT professional who may be attempting a minor to moderate RAID failure. These articles will help you asses the situations where a cautious RAID data recovery attempt may prove fruitful as well as those cases where inexperience may lead to further data loss.
DISCLAIMER: The content here is provided for information and illustration only. Data recovery is always an uncertain undertaking, and there are wide range of factors that will impact your chances for a successful recovery. Our content deals with typical cases, and a conservative approach is always recommended.

RAID Retrieval: RAID 0 vs. Raid 1 vs. Raid 5

RAID 0, RAID 1, RAID 5 and combinations of these (e.g. RAID 10) are the most common forms of RAID volume sets in use today. This article provides a brief overview of what each of these RAID levels consists of as well as what you should take into consideration while attempting a RAID retrieval.

RAID Retrieval Software

While each RAID retrieval job is unique, the tools of the trade for RAID recovery operations are fairly standard. This software provides a good starting point for evaluating your investment in RAID retrieval software and training.

RAID Retrieval Tips and Warnings

RAID retrieval, as mentioned above, is not something that should be undertaken lightly. Advice from the Internet or so-called gurus can lead to disaster if the basic guidelines of RAID retrieval aren’t followed. This article provides some useful general tips and warnings that apply to all RAID recovery endeavors.

RAID 0 Retrieval: Frequently Asked Questions

RAID 0 is a striped volume that offers no redundancy. RAID 0 volumes cannot be rebuilt on-the-fly, so when a single disk fails, you will be facing a data recovery challenge. This article provides reasonable expectations as well as specific tips for RAID 0 retrieval.

RAID 5 Retrieval: Frequently Asked Questions

RAID 5 volume sets are also striped volumes, but they include parity data. This allows the RAID to rebuild the data from the lost disk without interrupting service. However, RAID 5 volumes are still susceptible to data loss due to two failed disks, operator error, power outages and other circumstances. This article prepares you for a failed RAID 5.
