64GB SD Card Shows Only 8GB After Corruption: Can the Photos Be Recovered?
Possibly, but do not run another recovery scan until you know what the 8GB reading actually represents. In this r/datarecovery case, a 64GB Lexar Professional 1000x camera card suddenly became unreadable, Disk Drill found nothing useful, and the computer then showed only 8GB. That size mismatch is the most important clue because an 8GB volume on a 64GB physical card is very different from the physical card itself reporting only 8GB.
Do Not Repair It Yet
Do not format the card, run CHKDSK, resize partitions, or save anything back to it. The photos matter more than restoring the card's usable capacity.
Does 8GB Mean the Other 56GB Is Gone?
Not necessarily. Windows Disk Management shows both physical disks and the volumes or partitions inside them. Microsoft documents Disk Management as a tool for viewing drives and their partitions, so the next step is to compare the card's total disk size with the size of the visible volume.
Check the Physical Disk Size in Disk Management
Connect the card through one known-good reader, open Disk Management, and find the removable disk by its size and connection time. Do not initialize or format anything.
Choose the Recovery Path
- The physical disk is still about 59–64GB, but only an 8GB volume is visible: this points to a partition or file-system problem rather than the card physically shrinking. Do not extend or recreate the volume yet. If the card stays connected and reads normally, create a byte-to-byte image first, then recover from the image or clone instead of repeatedly scanning the original card.
- The physical disk itself reports only about 8GB: try one other known-good reader that supports the card type. If the card still reports the wrong total capacity, stop ordinary software scans. Recovery software can only work with storage the device exposes to the operating system; the missing address space is not available to scan normally.
- The capacity changes, the card disconnects, or reads become extremely slow: stop DIY attempts. Those symptoms make repeated scanning riskier, especially when the photos are irreplaceable. A professional flash-memory recovery service is the safer next step.
If Disk Management shows the full physical capacity and the card remains stable, a tool such as Recoverit Memory Card Recovery can be used on the readable card or a stable image, with recovered photos saved to another drive. If the physical device itself remains stuck at 8GB, do not keep switching between recovery apps—the problem is no longer simply which software to choose.
For the broader reasons an SD card can show the wrong capacity, see the SD card showing wrong size guide. For this case, however, the only decision that matters first is whether Windows still sees the full physical card.
