USB drive & memory card recovery

Drive not recognized, broken connector, unreadable SD card, vanished photos and videos. Small in size, complex in technique: drives and cards combine a controller, NAND memory and, often, a "Monolith" resin block. We handle them all, from USB drive to CFexpress.

Symptoms we treat

Does your device show one of these signs?

Broken / torn connector

Bent USB drive, connector desoldered after a drop or a wrong move in the port.

connector micro-soldering
Not recognized / 0 capacity

The drive or card no longer appears, asks to be formatted or shows a wrong size: controller or translation table down.

80%+ on logical failure
Deleted or formatted photos / videos

Camera or drone card wiped by mistake, formatted, or corrupted mid-shoot.

RAW / 4K data carving
microSD "Monolith" card

Oxidized contacts, cracked resin, mute card: the NAND and controller are embedded in a single block.

Spider Web technique
Our method

What the laboratory actually does.

Connector & board

Precision micro-soldering

Torn USB connector, cut trace, desoldered capacitor: under a stereo microscope, we rebuild the electrical connections to make the device readable again — long enough to extract the data.

Corrupt controller

Reverse engineering the FTL

When the device is no longer recognized, the translation table linking logical addresses to NAND pages is often corrupt. We access the controller in factory mode to rebuild it, without the original firmware.

Monolith card / drive

Spider Web technique

On microSD and monolithic drives, the NAND is embedded in the resin with the controller. We expose the internal contact points by controlled abrasion, then micro-solder wires onto them to read the memory — the so-called "Spider Web" technique.

Dead controller · chip-off

Board-level NAND extraction

If the controller is unrecoverable, we desolder the NAND chip, read its raw content, then reconstruct in software the interleaving, scrambling and ECC specific to the controller.

Photos & videos

Signature-based data carving

For files whose metadata is gone (format, corruption), we rebuild RAW, JPEG, MP4 and MOV by recognizing their binary signatures — including fragmented 4K video.

What you must never do to a failing drive or card

  • Keep using it or take new photos — every write overwrites recoverable data.
  • Accept the OS's "format the disk?" prompt — a format badly complicates recovery.
  • Force a bent USB connector into the port — risk of tearing off the NAND or breaking traces.
  • Run repair software repeatedly — it writes to the device and lowers the odds.
  • Try to "fix" a Monolith card yourself — abrasion without proper tooling destroys the contact points.

The golden rule: remove the device, stop all writes, and hand it over. For photos, take no further images on the affected card.

FAQ

Specialist answers.

My USB drive isn't recognized — files recoverable?+
Yes, in most cases. If the failure is logical or electronic, we repair by micro-soldering or rebuild the translation table. If the controller is dead, we read the NAND directly by chip-off. Stop using the drive and don't format it.
I formatted my SD card — are my photos lost?+
Not necessarily. As long as the card hasn't been reused, photos and videos often remain recoverable by data carving (RAW, JPEG, MP4 signatures). Remove the card and take no more photos on it.
What is a "Monolith" card or drive?+
On microSD and many recent drives, the NAND and controller are embedded in a single resin block. Recovery requires exposing the internal contact points by abrasion (Spider Web technique), then reading the memory by micro-soldering.
My drive's connector is broken — is it repairable?+
Yes. A torn connector or cut traces are repaired by micro-soldering. The goal isn't to reuse the drive, but to make it readable long enough to extract your data.
How much does recovery cost?+
The flat fee starts at €300 excl. VAT, up to €950 excl. VAT for a chip-off or a Monolith card. Free diagnosis, no data – no fee: only €25 due if we fail.
