SD Card Shows 0 Bytes in Windows: Fix and Recover

When an SD card shows 0 bytes, Windows cannot read its file system or capacity correctly. The card may be corrupted, locked, unsupported by the reader, or physically failing.

Do This First

• Stop saving new files to the SD card.
• Try another card reader or USB port.
• Check the lock switch on a full-size SD adapter.
• Do not format the card before recovering important photos or videos.

Check the SD Card in Windows

1. Open Disk Management and check whether the card has a drive letter.
2. If it shows RAW, unallocated, or 0 bytes, avoid quick formatting until files are recovered.
3. Open Command Prompt and run chkdsk X: /f only when the card still has a readable file system.
4. If Windows asks to format the card, click Cancel.
5. After recovery, format the SD card or replace it if errors return.
