data recovery FAQs
What types of storage devices can you recover data from?
We recover data from many types of storage, including hard drives, SSDs, RAID arrays, NAS systems, servers, Macs, smartphones, USB flash drives, memory cards, virtual machines, helium HDDs, external storage, and supported cloud-connected environments. The available recovery method depends on the device, failure type, and condition of the original storage.
Can data still be recovered when a device is not detected?
Often, yes. A device may stop being detected because of mechanical, electronic, firmware, controller, file-system, or other storage problems while recoverable data remains available. Our engineers evaluate the original device to determine the safest recovery path.
How quickly will my device be evaluated?
Your device is examined within 2 hours after it arrives at our San Jose lab. After the evaluation, we provide the available recovery options and a fixed quote before recovery work begins.
Do you perform all data recovery work in-house?
Yes. All diagnostics, imaging, recovery, file reconstruction, and verification are performed in-house at our San Jose lab. We never outsource your device or data to third-party data recovery companies.
