RAID 4 Data Recovery and Repair Services

Although RAID 4 is one of the least common RAID configurations, there are thousands of RAID 4 systems in the United States alone. Many of these arrays act as network storage servers, and RAID 4 data loss is often disastrous.

Raid 4 Recovery

While RAID 4 offers some fault tolerance, data loss is still an occasional issue.

Common causes of data loss on RAID 4 systems include:

  • RAID Controller Failure
  • Permanent Parity Loss
  • Multiple Hard Drive Failures Past Point of Fault Tolerance
  • Accidental File Deletion
  • Unintentional Formatting or Partitioning
  • Virus or Malicious Software Damage
  • Electronic Damage
  • Operating System Failure

When your RAID 4 fails, you need a RAID data recovery company that can provide you with fast access to a working copy of your data.

At Secure Data Recovery Services, we specialize in RAID 4 data recovery and repair. Our engineers have significant experience with NetApp devices and other RAID 4 systems, and we offer fast results for our clients through dozens of state-of-the-art facilities.

We offer risk-free diagnostics for all RAID 4 systems. Contact our customer service team to start a case or read on for an overview of RAID 4 technology and our RAID services.

An Overview of RAID 4 Technology

Raid 4 Data Recovery

A RAID 4 stripes data across two or more disks at a block level. The blocks range in size from 16-128 kilobytes. A dedicated parity disk holds information that allows array to quickly find and access data. If a single hard drive fails, the RAID will not lose data; the array can access the parity disk and rewriting data from the damaged member to a new, working hard drive.

RAID 4 is fundamentally similar to RAID 3 and RAID 5. However, RAID 3 uses byte-level striping instead of block-level striping, and RAID 5 distributes parity information over all of the disks in the RAID.

RAID 4 offers some fault tolerance, but parity loss is a potentially serious issue. RAID 4 also has a serious performance bottleneck in its dedicated parity drive, and RAID 5 generally offers better performance as a result. However, some businesses use RAID 4 with unconventional parity strategies in order to avoid potential downtime. RAID 4 is most useful for network-attached storage and in other applications where uptime is critically important.

Common Data Loss Symptoms for RAID Arrays

A RAID 4 array can fail for a number of reasons, and data recovery engineers need to perform a full system analysis before attempting repairs in order to avoid potentially serious consequences.

Some of the most common data loss symptoms include:

  • Clicking or Whirring Sounds from RAID Member Drives
  • Error Messages Indicating File Corruption
  • Disappearing or Inaccessible Files
  • Virus Infection Error Messages
  • RAID Controller Does Not Recognize Hard Drives

While some of these symptoms indicate a specific type of failure scenario, it is impossible to accurately diagnose a RAID failure without performing a physical media evaluation. Secure Data Recovery Services' experts can assess media damage within 24 hours, providing you with a risk-free analysis of your RAID failure event. Our evaluation reports include a price quote and a turnaround estimate. When possible, we will also include a list of recoverable files.

Dedicated Technology for RAID 4 Repair and Data Recovery

After you approve our data recovery evaluation report, our engineers will repair physically damaged RAID members in a Certified Class 10 ISO 4 Cleanroom, which protects exposed hard drive components from dust and other potentially hazardous contaminants.

No data recovery company can safely work with physically damaged media without an appropriately controlled laboratory, and Secure Data Recovery Services was the first provider to earn a Cleanroom certification under Class 10 ISO 4 specifications. These standards allow for a strict maximum of 10 particles per cubic foot of laboratory space.

Our engineers use specialized tools to safely restore damaged RAID 4 hard drives to an operable condition, at which point we can reconstruct your array and treat logical data issues. Because we have experience with NetApp and other RAID 4 implementations, we can quickly treat file damage to control your turnaround time.

We typically return recovered data via secure FTP or on dedicated external media. Contact our customer service team at 1-800-388-1266 to discuss return media options or to start a case.

Secure Data Recovery

A Certified Source for RAID 4 Data Recovery

As RAID 4 is a popular configuration for network-attached storage servers, data recovery companies need to exercise extreme caution when handling data from damaged systems.

Secure Data Recovery Services holds a SSAE 16 Type II Certification, and we were the first data recovery provider to successfully earn this credential. SSAE 16 Type II certification requires annual tests, network audits and staff protocol interviews.

Our other credentials include:

  • SAS 70 Certification
  • PCI Security Certification
  • Green Business Certification
  • General Services Administration Contractor Certification

Secure Data Recovery Services is also a member of the Information Systems Security Association, unlike most other RAID data recovery companies; we offer full access to all of our security reports online. Visit our certifications page to view audit report, attestation comments and more.

We handle hundreds of RAID data recovery and repair cases each year for Fortune 500 clients, government offices and other high-security clients. To view letters from our RAID data recovery clients, visit our testimonials page.

Fast Turnaround Times and High Recovery Rates

RAID failures can challenge your business's day-to-day activities. Secure Data Recovery Services offers several turnaround options to help you limit system downtime when necessary.

Our RAID experts can complete most cases within two to five business days depending on the size of your array, its block size, the condition of your RAID media and several other factors. We will present an accurate, case-specific turnaround estimate after evaluating your device.

If you need faster service, we offer an expedited 24/7/365 service. This option gives you the fastest possible results in emergency situations. Our engineers often complete emergency cases in less than 48 hours.

Secure Data Recovery Services also offers RAID repair services. We can restore your damaged RAID 4 to a working condition while performing data recovery services, greatly limiting your productivity losses following a major hardware failure. Contact our customer service team for details.
