What file systems do you support for data recovery?

We support all major file systems including NTFS, FAT32, FAT16, exFAT, HFS+, APFS, ext2/ext3/ext4, XFS, ZFS, Btrfs, ReFS, UFS, and proprietary NAS file systems from Synology, QNAP, Buffalo, and NetApp.

How long does data recovery take?

Standard recovery takes 3-7 business days. Emergency service available in 24-48 hours. Complex RAID or severely damaged drives may take 1-2 weeks.

Do you offer a no-data-no-fee guarantee?

Yes. If we cannot recover your critical files, you pay nothing for the recovery attempt. Free evaluation determines recoverability before any commitment.

Recovery Methods

Data Recovery Methods & Techniques

We use industry-leading techniques and specialized tools to maximize data recovery success.

Logical Recovery

Best for: Deletions, formatting, corruption

Software-based recovery for drives that are physically healthy but have logical damage. We scan for deleted files, rebuild file systems, and extract data without opening the drive.

Techniques: File carving, signature scanning, MFT analysis, journal recovery, partition reconstruction

Cleanroom Recovery

Best for: Mechanical/physical failures

Physical recovery performed in ISO Class 5 cleanroom environment. We repair or replace damaged components including heads, motors, and PCBs to access the platters.

Techniques: Head replacement, platter transplant, motor swap, PCB repair, firmware patching

Chip-Off Recovery

Best for: SSDs, USB drives, memory cards

Advanced technique for flash storage where NAND chips are physically removed and read directly. Used when controller is damaged or encryption bypasses are needed.

Techniques: NAND chip extraction, raw dump reading, ECC correction, wear leveling reconstruction

RAID Reconstruction

Best for: Multi-drive arrays, NAS, SAN

Virtual reconstruction of RAID arrays without original controller. We analyze stripe patterns, parity data, and drive order to rebuild the logical volume.

Techniques: Stripe analysis, parity calculation, block order detection, destriping, array simulation

How It Works

Our Recovery Process

A proven 6-step process that maximizes your chances of successful data recovery.

Free Evaluation

Send your device or contact us for assessment. We diagnose the issue and provide a detailed quote within 24-48 hours.

Quote Approval

Review our detailed quote with success probability. No obligation - approve to proceed or we return your device free of charge.

Forensic Imaging

We create a sector-by-sector clone of your drive to work from. Your original media is preserved and never altered.

Data Extraction

Using appropriate techniques based on failure type - logical, cleanroom, chip-off, or firmware repair - we extract your files.

Verification

We generate a file listing for your review. You verify that critical files are recovered before finalizing payment.

Data Delivery

Recovered data delivered on new external drive, cloud upload, or encrypted transfer. Original device returned if requested.

FAQ

Frequently Asked Questions

Get answers to the most common questions about our data recovery services.

We recover data from all storage media including hard disk drives (HDD), solid state drives (SSD), RAID arrays (all levels), NAS devices (Synology, QNAP, Buffalo), SAN storage, USB flash drives, SD/microSD/CF memory cards, optical media (CD/DVD/Blu-ray), and tape storage (LTO, DLT, DAT). We support all major brands including Seagate, Western Digital, Samsung, Toshiba, Crucial, and more.

We support all major file systems including Windows (NTFS, FAT32, FAT16, exFAT, ReFS), Mac (APFS, HFS+, HFS), Linux (ext4, ext3, ext2, XFS, ZFS, Btrfs), and enterprise/NAS file systems (Synology SHR, QNAP, NetApp WAFL, VMFS). We also recover from virtual disk formats (VMDK, VHDX, VDI, QCOW2).

Pricing depends on media type and failure severity. Logical recovery (deleted files, formatting) starts at $299. Physical HDD recovery starts at $499. SSD recovery starts at $599. RAID/NAS recovery starts at $799. We provide free evaluation with no-obligation quote. Emergency rush service available at additional cost.

Our overall success rate is 95%. For logical failures (deleted files, formatting, corruption), we achieve 98%+ success. Physical HDD failures average 90% success. SSD failures average 85% success. We provide honest assessment during free evaluation - if recovery is not possible, we tell you upfront.

Evaluation: 24-48 hours. Logical recovery: 3-5 business days. Physical recovery: 5-10 business days. RAID/complex cases: 7-14 business days. Emergency service: 24-48 hour turnaround available. Timeline estimate provided after free evaluation.

Yes. Clicking or grinding sounds typically indicate mechanical failure - damaged heads, failed motor, or platter issues. Do not power on the drive as this can cause further damage. We perform cleanroom recovery with head replacement or platter transplant. Success rate for clicking drives is approximately 85-90%.

Yes. We specialize in SSD recovery including controller failure, NAND chip damage, firmware corruption, and wear leveling issues. For severely damaged SSDs, we perform chip-off recovery - removing NAND chips and reading data directly. Note: TRIM-deleted files on SSDs are generally not recoverable due to how SSDs handle deletions.

Yes. Quick format only erases file system pointers - actual data remains on disk. Full format is also recoverable in most cases. Critical: Stop using the drive immediately after formatting. New data written to the drive overwrites original files permanently. The sooner you contact us, the better the recovery chances.

Yes. We recover from all RAID levels (0, 1, 5, 6, 10, 50, 60) and handle multiple drive failures, failed rebuilds, controller failures, and configuration loss. We can reconstruct arrays without the original controller by analyzing stripe patterns and parity data. NAS devices (Synology, QNAP, etc.) are also supported.

Absolutely. All recovery work performed in secure facility with restricted access. We sign NDAs on request. Recovered data is encrypted during storage and transfer. All copies are securely destroyed after delivery confirmation. We are HIPAA and GDPR compliant for healthcare and EU clients.

If we cannot recover your critical files, you pay nothing for the recovery attempt. The free evaluation determines recoverability before any charges. You approve the quote and file list before we proceed. You only pay when we successfully recover your data. Evaluation and return shipping are always free.

Stop using the drive immediately. Pack in anti-static bag (we can send one). Surround with 2+ inches of cushioning material. Use sturdy box - not envelope. We can provide prepaid shipping label upon request. Do not open the drive casing or attempt DIY recovery on physically failing drives.

It depends on the ransomware variant. For some older variants, decryption keys are available. For others, we may recover previous versions, shadow copies, or unencrypted backups. We can also recover files that existed before encryption if they were not overwritten. Success varies - we provide honest assessment during evaluation.

Yes. We offer 24-48 hour emergency service for critical situations. Emergency cases are prioritized and worked on immediately upon receipt, including nights and weekends. Additional fees apply for rush service. Contact us immediately for emergency data loss - time is critical.

Your original device is returned to you after recovery unless you request otherwise. If drive is non-functional after physical recovery, we can provide certificate of destruction if needed. Recovered data is delivered on new external drive, USB, or via encrypted cloud transfer - your choice.
