SanDisk SD Card Data Recovery – Intermittent Disconnection Specialists

At Cardiff Data Recovery, we’re Wales’s leading provider of expert Sandisk SD card data recovery services. With over 25 years of experience, we specialise in recovering data from memory cards that are physically or electronically unstable—including cases where a SanDisk Ultra microSDXC card disconnects or reconnects intermittently.

If your SD card is no longer stable when connected, keeps dropping in and out, or is unrecognised by devices, it may indicate damaged connectors, power instability, or internal controller issues. Our engineers can recover the data even if your system cannot maintain a consistent connection to the card.

⚠️ Symptoms of an Unstable SanDisk SD Card

  • Card appears and disappears in File Explorer or Disk Utility
  • Transfer progress stalls or is interrupted
  • Error messages such as “Please insert a disk into drive” or “Drive not accessible”
  • No response from cameras, phones, or card readers
  • Files present but cannot be copied
  • SD card becomes warm or causes reader to freeze
  • Light flickers or no light on card reader intermittently

These issues are common with older or physically worn SD cards, especially after extended use, repeated insertions, or exposure to moisture or static.

🛠️ How We Recover Data from a Faulty SanDisk Ultra SD Card

1. Initial Diagnostics and Contact Point Inspection

  • The SD card is examined under magnification to assess the condition of the gold-plated contact pads
  • We test the card in multiple professional-grade card readers to confirm instability
  • Loose or corroded contacts are cleaned using non-abrasive solutions
  • The card is connected via low-level forensic interface to ensure read-only diagnostics

If physical contact is intermittent, we proceed with manual pad bridging or adapter-level stabilisation.

2. Stabilising the Electrical Connection

  • For cards that connect briefly but then fail, we bypass standard readers using a custom microSD bench adapter
  • Controlled power supply ensures voltage consistency, reducing disconnection risk
  • Clock and command signals are monitored to detect errors during read attempts
  • Once stabilised, the card is prepared for a full data image

3. Bit-by-Bit Imaging and ECC Recovery

  • A sector-by-sector clone of the SD card is created using imaging tools capable of handling unstable media
  • The imaging tool is set to retry failed reads using ECC-assisted algorithms
  • We track and map bad or partially readable sectors, extracting usable data as the card fails
  • For extremely degraded media, imaging is performed in slow-read mode, which prevents overloading the controller

4. File System Repair and File Recovery

  • Once imaging is complete, the logical volume (typically FAT32, exFAT, or NTFS) is reconstructed
  • Fragmented, incomplete, or hidden files are recovered via deep scan
  • Original folder structures (e.g., DCIM, Photos, Video, WhatsApp, Documents) are restored
  • File types recovered may include:
    • Photos (.JPG, .PNG, .CR2)
    • Videos (.MP4, .MOV, .AVI)
    • Documents (.DOCX, .XLSX, .PDF)
    • App-specific data (e.g., voice notes, backups)
