SanDisk USB and Memory Card Recovery: SD, microSD, Extreme, Ultra

Quick answer: Is your SanDisk USB drive or card not reading, asking to format, or are your photos gone? Do not panic but act right: write nothing new and do not format. USB and card cases are often logical (file system corruption) and recover with high success. DSET recovers SanDisk SD, microSD, Extreme, Ultra, Cruzer and other flash media. First diagnosis free, no data no fee. Info: +90 536 662 38 09.

Why microSD and USB are special cases

Unlike a hard drive, microSD cards often combine controller and NAND in a single monolithic chip. This makes recovery harder when the card is broken or burnt, the classic chip off method needs special technique and pinout solving on monolithic cards. USB drives may have separate controller and NAND, a different approach. Known SanDisk controller architectures help an experienced lab.

Most common SanDisk faults

Symptom	Likely cause	Approach
"Format the disk"	File system (FAT/exFAT) corruption	Do not format, logical recovery
Lost photos	Wrong removal from camera/phone	Deleted file scan
Wrong capacity / 0 bytes	Controller failure	Controller level access
Not recognized at all	NAND or controller death	Chip level read
Physical breakage	microSD fragility	Chip off, pinout solving

See USB not reading and SD card corrupted.

Key rule, do not format or write

Do not accept the format prompt, do not take new photos or copy files, overwritten data does not return. If the card is in a camera, power it off and remove it.

Beware fake/inflated cards

Some cheap cards are faked to show more than their real capacity and silently corrupt data past a point, we detect this in diagnosis.

Why DSET

Since 2003, USB and card cases are usually the lowest price range, and we have experience with hard monolithic microSD and chip off cases. See the price list.

FAQ

Formatted by mistake? Still recoverable if nothing was written, stop using it now. Broken or burnt microSD? Possible via chip off and pinout solving if the NAND is intact. Deleted photos back? Often, if not overwritten. Which products? SD, microSD, Extreme, Extreme Pro, Ultra, Cruzer, iXpand and all brands.
