When an SD card becomes unreadable, every next step matters. For photographers, videographers, and business users, a failed memory card can put active work, client delivery, and irreplaceable files at risk.
This case study explains how PITS Data Recovery handled a SanDisk SD card data recovery case involving inaccessible video footage, encryption complications, and logical file-system damage after failed software attempts.
Customer Situation
The customer was a professional videographer who stored footage from a recent shoot on a SanDisk Extreme Pro SDXC 256GB memory card. The footage was needed for editing, client delivery, and project completion.
The issue started when the customer could not access the files because the card had been encrypted and the password was forgotten.
This created immediate pressure: delayed post-production, potential missed delivery expectations, and risk to the customer’s professional reputation.

What Went Wrong
After losing access to the encrypted card, the customer attempted to use third-party recovery and decryption software. Instead of restoring access, the software damaged the card’s logical structure.
The SanDisk memory card then became unreadable. The video files were inaccessible, and the original folder structure was no longer available. This changed the case from an access problem into a logical failure involving corrupted exFAT file-system records and damaged metadata.
This is where DIY recovery becomes dangerous. When software modifies a damaged file system or scans aggressively without a controlled image, it can compromise the same metadata needed to rebuild usable files.
How PITS Approached the Recovery
Step 1: Preserving the Original Card
PITS engineers created a full sector-by-sector image of the SanDisk card. This protected the original media from additional changes during recovery.
Step 2: Analyzing the exFAT File System
The team analyzed the exFAT file system and identified corrupted file-system records caused after failed third-party software attempts.
Step 3: Rebuilding the File Tree
Engineers rebuilt the damaged file tree to locate recoverable video files and restore directory relationships where possible.
Step 4: Working From a Virtual Disk Image
The recovery was performed through a virtual disk image, allowing engineers to reconstruct the logical structure without working directly on the original card.
Step 5: Restoring Metadata From Backup Areas
Where primary file-system data was damaged, engineers used backup file-system areas to restore missing metadata and recover usable video files.
Why Professional Recovery Mattered
This case required more than standard recovery software. The card had encryption access issues, corrupted exFAT records, missing folder structure, and additional damage from third-party tools.
PITS succeeded because the recovery workflow preserved the original card first, then rebuilt access from a controlled image. That process reduced avoidable risk and gave engineers a safer path to reconstruct usable files.

Industry-Leading 99% Success Rate
No hidden fees. No surprises. Just expert data recovery you can trust. We handle everything from simple file loss to extreme data recovery cases. If we can’t recover your data, no one can.
Recovery Outcome
PITS recovered 99.6% of the files from the SanDisk Extreme Pro SDXC 256GB memory card. Approximately 238 GB of video footage was restored, verified, and returned to the customer in usable condition.
The original folder structure was restored where possible, making the recovered footage easier to review and move into post-production. The customer regained access to the critical video files needed to continue the project without starting over.
What Not to Do After Data Loss
After SD card data loss, avoid actions that can reduce recovery potential:
- Do not keep using the card. New activity can overwrite recoverable data.
- Do not format the card. Formatting can destroy file-system metadata.
- Do not run repeated recovery tools. Multiple scans can worsen logical corruption.
- Do not save files back to the same card. This can overwrite the original data area.
- Do not test decryption tools on the original media. Recovery work should start from a protected image.
The safest move is to stop using the card immediately and request a professional evaluation.
