What Causes RAID Data Corruption?

Data corruption is fairly uncommon on most RAID arrays thanks to a number of safeguards that protect against common sources of file loss. However, when corruption does occur due to logical or physical issues, RAID users often face serious consequences.

What Causes RAID Data Corruption?

Although redundant RAID configurations protect against hard drive failures, most setups will not provide protection from data corruption.

Some of the most common causes of RAID file corruption include:

  • Virus Damage
  • Physical Media Failures
  • Controller Issues
  • Sudden Power Outages and Electrical Events
  • Software Errors and Malfunctions

Because most RAID systems will detect hard disk failures and adjust accordingly, data corruption due to a single hard drive failure is unlikely on RAID 5, RAID 1 and other common configurations. A notable exception is RAID 0, which is not redundant. Logical (software-based) corruption is far more likely for most arrays, but data recovery engineers need experience with both logical and physical failure scenarios to treat RAID file corruption.

At Secure Data Recovery Services, we specialize in RAID data recovery and array repair. Our engineering teams have significant experience with all types of RAID data corruption, and by using a unique team-oriented approach, we give each case the attention it needs for fast, reliable results.

We offer free media diagnostics for RAID 0, 1, 5, 10, 6 and all other configurations. Contact us today to set up an evaluation or for more information.

Avoiding Data Loss When Treating Corrupt RAID Systems

You should immediately back up functional data before attempting to treat RAID file corruption. If the corrupt files are critically important, you should contact a professional data recovery company before taking any further actions.

Do not run chkdsk on a RAID array if you suspect that a physical media issue is causing file corruption. Filesystem utilities can cause data loss on degraded striped arrays, and we regularly receive RAID 5 systems that are inaccessible due to a chkdsk process.

Do not run data recovery software on a RAID array. Most data recovery utilities are designed for non-striped data and may cause file access issues. Never try to rebuild a failed array if you have a problem with widespread data corruption or filesystem corruption. The best course of action is to shut your system down to preserve your files in their current condition and to contact a professional data recovery provider.

Choosing a Reliable RAID Data Recovery Provider

RAID arrays can lose data in hundreds of ways, and data recovery companies should have experienced engineering teams that can create an appropriate strategy for any failure scenario. Even when RAID data corruption was clearly caused by a certain event or file process, engineers might need to try several strategies to restore damaged files.

Factors that can affect the data recovery process include:

  • Number of RAID Hard Drives
  • Extent of File Corruption
  • Operating System and Filesystem
  • Location of Corruption
  • RAID Configuration Level
  • Controller Type

Secure Data Recovery Services' engineers have years of experience with all common RAID configurations. We can treat corrupt databases, email archives and other large files with proprietary utilities, and if your array has physically damaged hard drives, we can perform essential repairs in our Certified Class 10 ISO 4 Cleanroom. Cleanroom technology filters potentially harmful particles from the data recovery work space, allowing for more reliable physical repairs.

We always make complete clones of all RAID drives before treating corrupt files in order to preserve your original media. Secure Data Recovery Services offers fast, safe RAID repair and recovery, and our free diagnostics give you an easy way to assess RAID data recovery costs before committing to the process.

A Secure Option for RAID Data Recovery

RAID arrays typically contain hundreds of sensitive and protected files. To keep your data safe, you need a secure data recovery provider with up-to-date networks and media access protocols.

Secure Data Recovery Services has an advanced set of security credentials. We were the first RAID data recovery company to earn a SSAE 16 Type II Certification and one of the first providers to join the United States General Services Administration's contracting schedules.

Our credentials include:

  • PCI Security Certification
  • Information Systems Security Association Member
  • SAS 70 Certification
  • SSAE 16 Type II Certification

If your RAID array has corrupt or inaccessible files, contact Secure Data Recovery Services to schedule free media diagnostics. Our engineers can accurately determine the causes of RAID file corruption, and within 24 hours we will provide a media failure report with a turnaround estimate and price quote. We offer several service levels for RAID data recovery including a 24/7/365 emergency service with a 48-hour average turnaround.
