There are two reasons: The first one is related to the unit of capacity. When card manufacturers say “MByte”, “M” means “Mega” which is equivalent to million (=106). On the other hand, Windows or other Operating Systems define “M” as 1024 times 1024 (=220). According to the fact, 256MByte is equal to 256000000 Byte as a definition of card manufactures, which is equivalent to 244MByte as a definition of Windows. The second one is related to the card itself. In general, memories on a card are consumed by not only the users but also by the card itself. For example a card needs management area or spare area. In addition, DOS (Windows) format needs some area even though it is very small.

Our card is compliant with a specification issued by each card association such as SD card Association or CompactFlash® Association. Therefore our card should work with the electronic equipment which satisfy the specification. However some problems may still be experienced. One of the major reasons is the “format issue” described in Q&A below. We recommend you format the card with the camera before using the card.

Please note that the format operation will erase all contents of the card.

The Performance of a card depends on several factors such as performance of the PC, interface between PC and the card, file system’s overheads, size of data transferred and so on. On the other hand our specification is defined as a case with ideal conditions. Therefore your benchmark result might be different from the specification.

As shown in the specification, our high performance series has a higher speed write operation compared with the standard series. However, the difference might appear small in some digital cameras because the overheads of the camera, such as compression of a picture might be rather large. On the other hand the difference will be greater for high-end digital cameras with high resolution, especially with a continuous shooting function.

In some electronic equipment which has SD card slots, MMC cards can be accepted. However SD cards cannot be used with electronic equipment which support only MMC cards, because a SD card is thicker than a MMC card even though other dimensions are same.

Please check with the manufacturer of the equipment.

The size of picture depends on resolution, compression method and quality of picture.

There are several types of format and for example when Windows XP formats a card FAT32, a file system is chosen as a default but some digital cameras might not support the FAT32 file system. Therefore we recommend that you format a card with the digital camera before using the card with the camera.

Please check the user’s manual or ask the manufacturer of the camera how to format the card with the camera.

Unfortunately not. Toshiba does not sell either the miniSD card adapter, the microSD™ card adapter or USB cap separately.

You will find necessary software on https://www.sdcard.org/downloads/formatter_4/

No, Please make sure that Card Reader support SDHC™ card format. There are many types of card reader available in market

In general:

Maximum data transfer speed may vary depending on the host device and file size. UHS-I is the ultra-high speed interface
in SD Memory Card Standard Ver.3.0

Situation:

With the adapter and Micro SDHC™ I EXCERIA™ Type HD runs the risk of consumers to connect two devices together, where the transmission speeds does not match.

Problem:

It happens sometimes some digital cameras generate data dropouts when writing to the card with adapter. In this case, image content is lost.

Solution:

To ensure that no image content is lost, it is recommended not to use any adapters. Better to use a card that supports the camera guaranteed.

USB Flash Memory TransMemory™ is formatted at the factory. If you need to format one again, use your computer.

Yes, you can.

Check the following items when removing USB Flash Memory TransMemory™ from the device.

On Windows© 98 Second Edition, be sure that the application (reading or writing of data) has finished operations, and that the access lamp on the USB Flash Memory TransMemoryD™ is not flashing.

On Windows© Millennium Edition, Windows© 2000 Professional, Windows© XP and Windows© Vista™, make sure that in the task bar USB Flash Memory TransMemory™ has ended and it is safe to remove it.

For Mac OSs, make sure that the TransMemory™ icon has disappeared before removing it.
