NAS SAN DAS Data Recovery Services

Network Attached Storage (NAS) devices are widely used for home and business storage. When a NAS fails, it can affect multiple users and disrupt everyday operations. Our NAS drive recovery service covers all major NAS devices and RAID arrays, including RAID 0, RAID 1, and RAID 5. Whether your NAS suffered logical corruption, physical drive damage, or a failed rebuild, we have the skills, data recovery tools, and knowledge to restore your lost data securely. H2: SAN Drive Recovery Storage Area Networks (SANs) provide flexible, large-scale data storage, but failures can be complex. Our SAN drive recovery services support environments affected by:

• Deletion or re-initialisation of LUNs
• Two or more drives failing or going offline
• Addition of incompatible hard drives to the array
• Hardware or software malfunction

From enterprise servers to advanced fibre channel systems, our engineers deliver complete SAN recovery solutions, ensuring data integrity and minimal downtime.

Direct Attached Storage (DAS) is widely used for fast, direct storage access. When a DAS device fails, it can compromise critical files. Our DAS drive recovery services cover both single and multi-disk configurations, including common DAS RAID setups. We support recovery from drive corruption, accidental formatting, controller issues, and even physical disk damage. No matter the failure, our goal is to provide a safe, professional RAID recovery service tailored to your DAS system.

Our engineers have extensive experience recovering from a wide range of failures, including:

• Deletion or re-initialisation of LUNs (SAN specific)
• Two or more hard drives failing or going offline
• Addition of incompatible hard drives to the array
• Hardware and software malfunctions
• Virus infections, operating system, or software upgrades
• Natural disasters such as fire or flood
• Physical damage to storage media

We provide recovery for devices from all leading manufacturers, including:

• Hitachi
• HP
• Snap Server
• NetApps
• Storevault
• TEAC
• IBM
• FortuNAS
• Intel
• U. S. Robotics

If your system is not listed, contact us; chances are we already have experience working with it.

NAS, SAN, and DAS systems are often used to store large volumes of business-critical or creative data. Our recovery services cover a wide range of file types, including:

• Virtual machines: VMDK, VHD, VHDX
• Databases: SQL, Oracle, Exchange, MySQL
• Business documents: DOC, XLS, PPT, PDF
• Multimedia files: JPEG, PNG, TIFF, RAW images, MP4, MOV, AVI video formats
• Email archives: PST, OST, EDB
• Backup files: proprietary system backups and disk images

Even if standard file recovery software cannot access your storage system, our engineers use the best data recovery software and in-house tools to ensure lost data can be restored wherever possible.

We support NAS, SAN, and DAS recovery across a wide variety of devices and environments, including:

• Small office and home NAS servers
• Enterprise-level SAN arrays
• DAS devices for direct storage access
• Cloud-integrated storage solutions
• Virtualisation platforms and servers
• Multi-disk RAID storage systems

No matter the scale of your storage environment, we can tailor our approach to your device and data requirements.

Our recovery process is designed to be secure and efficient:

1. Free Evaluation - We begin with a no-obligation assessment to diagnose the problem
2. Secure Imaging - Drives are imaged sector by sector to preserve the original media
3. Advanced Recovery - We reconstruct arrays and repair file systems using specialist data recovery software and hardware
4. Data Verification - You review the list of recoverable files before approval
5. Delivery - Data is returned on a secure external device

Unlike generic file recovery software, our methods combine proprietary data recovery tools, cleanroom technology, and expert knowledge of RAID structures to achieve the highest possible success rate.

There are several reasons to choose us to help recover deleted files and lost data, including the following:

• Over 25 years of experience in NAS, SAN, and DAS recovery
• Expertise in RAID configurations, including RAID 0, RAID 1, and RAID 5
• High success rates in complex recovery cases
• No data, no fee guarantee for peace of mind
• GDPR compliant processes ensuring data security
• Emergency services available for critical systems

From small office NAS devices to enterprise SAN environments, Disk Doctors provides complete storage data recovery solutions.

We understand that downtime can be critical for businesses and organisations. That is why we offer emergency recovery services for NAS, SAN, and DAS failures. Our engineers are available to prioritise urgent cases, helping you get systems back online quickly while ensuring your data remains secure. If you are dealing with a time-sensitive failure, contact us immediately for expedited support.

If you are facing NAS, SAN, or DAS failure, time is critical. The sooner you act, the better the chances of recovery.

Contact Disk Doctors today for professional NAS drive recovery, SAN drive recovery, and DAS drive recovery. As trusted storage data recovery experts, we are ready to restore your lost data quickly and securely using the best data recovery software, tools, and expertise available.

Can you recover data if multiple drives in a RAID fail?

Yes. Even if two or more drives fail or go offline, our engineers can often rebuild the array and recover the data. The success of recovery depends on the RAID level, the condition of the drives, and whether there have been attempts to rebuild the array after failure. In many cases, even heavily degraded arrays can still be reconstructed using specialist data recovery tools and in-depth knowledge of RAID architecture. By avoiding DIY fixes and seeking professional help quickly, you significantly increase the chance of a full recovery.

What if my SAN system lost LUNs?

We specialise in SAN recovery, including cases where LUNs have been deleted or re-initialised.

Do you support physical damage recovery?

Yes. We can recover data from media damaged by fire, flood, or physical impact using cleanroom technology.

Which RAID levels do you support?

We recover data from all RAID levels, including RAID 0, RAID 1, and RAID 5.

How long does recovery take?

The timeframe depends on the type of failure and the complexity of the storage environment. Simple cases, such as a single NAS drive failure, may take only a few hours to complete. More complex scenarios, such as SAN systems with multiple failed disks or corrupted RAID arrays, can take several days as engineers carefully reconstruct data and verify integrity. We always provide a clear estimate after the initial evaluation, so you know what to expect.

Is my data secure during recovery?

Yes. We follow strict GDPR compliant procedures and ensure all data is handled securely and confidentially.

Disk Doctors guarantees protection of your data throughout the data recovery process, from evaluation to handing data back to the client.

1. Disk Doctor Employees are selected through a rigorous process of selection and follow our strict rules and procedures for handling the client data.
2. Client media is cloned sector by sector onto our own lab media and all the data recovery work is carried out on the cloned media not the original media; this ensures that client’s storage media is always intact.
3. Upon successful recovery Disk Doctors by default keeps a copy of the data for 7days before it gets deleted automatically from our Lab Server. This helps in providing the copy of data again if some thing goes wrong during the transfer of data to client e.g. the data media gets damage or goes missing during the postal process.
4. Our agreement to recover the data includes the clause for protection and non disclosure of data as per legal rules and regulations. If you require separate agreement for data protection and non disclosure, we are happy to sign the agreement.
