Windows says the SD card needs formatting

Updated October 2026

Click Cancel. Windows can't read the card's file system, but the photos underneath are usually intact, and a deep scan can find them without it.

You need to format the disk in drive E: before you can use it means Windows can't make sense of the card's file table. Formatting writes a new one and can make the photos harder to find. Recover them first, then format the card.

Recover them in four steps

  1. Stop using the card or driveDon't take more photos, copy files to it or format it. Every new file can overwrite one you want back.
  2. Connect it to your PC and open Data Recovery ProUse the PC's card slot or a USB reader. If Windows asks to format the card, click Cancel. Click Yes when Windows asks for permission, so it can read the card directly.
  3. Scan and previewThe quick scan takes seconds; the deep scan reads every block. Files appear as they are found, each marked intact, partly damaged or not checked, so you see what can be recovered before you decide.
  4. Recover to your PCChoose the files you want and save them to a folder on your PC or another drive, never back to the card. You only pay if you choose to recover more than the free allowance.

Questions

Should I run chkdsk?

Not yet. chkdsk writes to the card while repairing it. Recover the photos first.
