Factors Affecting Data Recovery on RAID 1

A RAID 1 consists of one or more disks that are mirrored, but not striped, to another set of disks. RAID 1 fulfills the RAID acronym (Redundant Array of Independent Disks) by offering true redundancy, but with notably slower performance than RAID 5 or other striped configurations for many applications.

Factors Affecting Data Recovery on RAID 1

Dozens of factors can affect the RAID data recovery process, but our knowledgeable staff can treat all failure scenarios effectively.

RAID 1 configurations are fairly reliable, but as is the case with any digital storage system, a RAID 1 array can lose data due to sudden disasters or major system failures. When data loss occurs, you should look for a data recovery provider with extensive RAID experience.

Secure Data Recovery Services' engineering teams specialize in RAID data recovery. We operate dozens of offices across the United States, and our experts treat hundreds of RAID arrays each year. We are extremely familiar with RAID 1 data loss and can provide fast service, affordable rates and free media diagnostics for all types of RAID systems. Contact us today to schedule a no-risk evaluation.

Common Causes of RAID 1 Data Loss

As is the case with RAID 5 and other redundant configurations, RAID 1 arrays often lose data during rebuilds. This can occur due to hardware or software errors, leaving users without access to critically important data. Rebuild failures are a major problem for larger RAID 1 arrays, as users may neglect to replace failed RAID members right away.

When a RAID rebuild failure occurs, it is important to keep the RAID powered off. Never attempt a second rebuild after a first rebuild fails. This can result in major overwrites and other serious data issues that will complicate data recovery attempts.

Most RAID 1 arrays have only one level of redundancy, and data loss can also occur when electronic or environmental events cause several simultaneous media failures.

Some of the most common causes of data loss on RAID 1 include:

  • Brownouts, Blackouts and Power Surges
  • Accidental Deletion or Formatting
  • File Corruption
  • Major Electronic Faults
  • Multiple Hard Drive Head Crashes
  • Fire and Water Damage

The extent of media damage and file overwrites greatly affect the chances of a successful RAID data recovery. To prevent unintentional media damage, you should turn your RAID off as soon as you notice failure symptoms. Early warning signs that can indicate RAID failure include loud clicking sounds on smaller systems, failed rebuilds, mount issues and file corruption errors.

Choosing a RAID Data Recovery Company

Data recovery companies use very different technologies to treat RAID arrays, and you should carefully look for a qualified provider for a reliable experience.

Among all of the factors that affect RAID 1 data recovery, laboratory outfitting is probably the most important. Qualified data recovery companies treat failed RAID media in a certified Cleanroom, which prevents airborne contaminants from coming into contact with the exposed internal components of hard disk drives. Secure Data Recovery Services uses a Certified Class 10 ISO 4 Cleanroom to keep client media as safe as possible. Class 10 ISO 4 specifications are extremely strict, and we maintain our certification through regular testing. Visit our Cleanroom page for more information.

Additionally, we have a number of specialized RAID tools including firmware repair equipment, RAID simulation computers and proprietary file utilities. Our engineering teams have experience with RAID data, which allows for higher recovery rates and more dependable results. We make full bit-level clones of all RAID media before using any data recovery programs or logical recovery techniques in order to keep your media safe from accidental overwrites or damage.

RAID data recovery companies should also follow strict security protocols to protect their clients' data. Secure Data Recovery Services was the first provider to earn a SSAE 18 Type II Certification, and we comply with all federal privacy laws.

Our certifications include:

  • PCI Security Certification
  • SAS 70 Certification
  • SSAE 18 Type II Certification
  • Information Systems Security Association Member
  • Green Business Certification

We offer high-security services through the General Services Administration contractor schedule. Contact our customer service team for more information or visit our certifications page for an overview of our credentials.
