This FAQ answers frequently asked questions from customers about Toshiba SD memory cards.

Problems

My memory card was working fine, why did it suddenly stop working?

Perform the following checks and actions.

• 1) Are you using an SD card that exceeds the capacity supported by the device?
  • →Check the capacity supported by the device.
  • ⇒* Even if you have been able to use the card, the device may not support the card's capacity.
    Continued use of a card on a device that does not support its capacity will lead to corruption and deletion of recorded data, and malfunction of the card.
    Note that just being able to use a memory card in a device does not mean that it is a compatible device.
• 2) Have you formatted the SD card on the device?
  • →SD cards are formatted at the factory. However, some instruction manuals for digital cameras, mobile phones and other devices, but not personal computers, may include instructions such as, "Format the SD card on the device before using it." If that is the case, follow the instructions in the instruction manual and format the SD card on the device.
• 3) There is a problem (bad connection, etc.) with the slot on the device.
  • →Is the SD card recognized when inserted into another device?
• If the above measures do not solve the problem:
  • →Format your SD card on a computer using specialized SD memory card formatting software 'SD/SDHC/SDXC Memory Card Format Software' (a separate window will open). Use an external SD card reader or a computer with an SD card slot that supports the capacity of your SD card.
  • * Always use the software above when formatting your SD card on a PC. The SD card will not be formatted correctly if you use your PCs standard format function.
  • * Even if you use the special software to format an SD card, before using the SD card on a digital camera, mobile phone, or other device, check the user documentation of the device to see if formatting on the device is required. Follow the instructions in the user documentation if formatting is required.
  • →If formatting your SD card on a PC using SD/SDHC/SDXC Memory Card Format Software does not solve the problem, contact the window in each region. click here.

The 2GB microSD card/SD card I bought was supposed to be 2GB. However, it's recognized only as a 1GB card.

A probable cause is that one of the devices you are using (SD card reader, cellular phone, digital camera, etc.) does not support a capacity of 2GB. Normally, 2GB cards cannot be used on devices that do not support a capacity of 2GB.
However, in rare cases, 2GB cards sometimes can be used.
If a card is mistakenly formatted on a device that does not support 2GB capacity cards, it will sometimes be formatted to the maximum capacity supported by that device (in this example, 1GB).
Use of cards on devices that do not support a capacity of 2GB might also result in malfunction.
Always check with the manufacturer of the device you are using to see if the device supports the capacity of the SD card you are using.
If the card is mistakenly formatted on a device that does not support a particular capacity, or the card's capacity is different from what it should be, you might be able to restore the card to its normal state by reformatting it using the SD memory card exclusive format software 'SD/SDHC/SDXC Memory Card Format Software (a separate window will open)' on your PC or on a card reader that supports the card's capacity.

• * The SD card will not be formatted correctly if you use your PC's standard format function. Always use the software above when formatting your SD card on a PC.

What devices are best suited to use of the UHS-I card?

Digital cameras, digital video cameras, and other devices that support UHS-I cards. Though only some digital camera, USB recorder, and other products are currently available, it is expected that a large number of digital cameras, digital video cameras, PCs, and other devices will support UHS-I in the future. A UHS-I card can be used on a current (non UHS-I compatible) device as the device supports the card's storage capacity and speed class.
