Warning: Formatting your flash card will erase all data files! 

FORMAT ON DEVICE (i.e. Digital Camera)
Most devices that support flash cards (i.e. camera) will have a format utility. Before using this feature, make sure the flash card capacity and type is supported by the device. Also make sure the format (e.g., FAT32) options offered by the device are compatible with other device you might plan to pair the flash card with. To format the card, follow the Format instructions provided in the user's manual of the device. 

Type "This PC" in the Windows search window and press Enter. Locate and highlight the drive that corresponds with the card reader containing the flash card. Then with the right mouse button, right-click the drive and select "Format" from the pop-up menu to access the format utility. 

Choose the file system that is appropriate for the card size and the device you plan to pair the flash card with. Note, 2GB and below (standard capacity) should use FAT, 4GB to 32GB (High Capacity) typically use FAT32. With capacities 64GB and above (Extended Capacity), we recommend using exFAT. Once you make this selection, click Format to complete the format process. 


If you are using a card reader connected to a macOS system, open the "Go" menu and double-click on Utilities (If you do not see Utilities, double-click on Applications and then double-click the Utilities folder). Double-click on the Disk Utility icon. On the Disk Utility Dialog box, select the flash card's active partition. Note: There will be two listings for the card, the first one is the active partition and the second is the volume label. Click the erase tab located on the right side of the screen. Using the Volume Format drop-down, select “MS-DOS File System” from the list. Click Erase.

  1. システムによっては大容量のカード (1GBや2GBなど)に対応していないことがあります。カードリーダーが内蔵された多くのシステムでは、新しいものであっても、対応しているカードに容量制限があります。お使いのカードがこの制限を超えている可能性があります。コンピュータの製造元が提供しているファームウェアのアップデートにより問題が解消されることがあります。コンピュータの製造元にて、ハードウェアまたはソフトウェアの修正をお確かめください。
  2. 2GBのカードに対応しているデジタルカメラや外付けのカードリーダーをお持ちの場合、一度コンピュータに接続してみてください。それら外部デバイスを通じてカードの中身を表示できた場合、内蔵のリーダーに問題がある可能性があります。
