High Capacity for SD Family
What are SDHC, miniSDHC, and microSDHC?
The SD High Capacity (SDHC
TM
) card, miniSD High Capacity (miniSDHC
TM
) card, and
microSD High Capacity (microSDHC
TM
) card are the new SD™ memory cards based
on the SDA 2.00 specification, introduced by the SD Card Association. This new SDA
2.00 specification enables SD cards to reach higher capacities: 4GB - 32GB
*
.
Because SDHC, miniSDHC, and microSDHC cards are recognized by new SDHC,
miniSDHC, microSDHC host devices differently
than standard SD, miniSD, and
microSD cards,
they are not backwards compatible with legacy SD, miniSD, and
microSD format host devices. Standard SD, miniSD, and microSD cards are
forward compatible with new SDHC, miniSDHC, and microSDHC host devices.
Legacy SD/miniSD/microSD host devices and SD/miniSD/microSD cards (up to
2GB) are FAT 16 file system compatible, while the new SDA version 2.00 file system
specification defines a SD FAT 32 file system for the new SDHC/miniSDHC/microSDHC
host devices and cards.
Be aware of non-SDA 2.00 specification compliant SD 4GB, miniSD 4GB, and microSD
4GB cards on the market. If these non-compliant SD/miniSD/microSD 4GB cards record
data in a SDHC host, and are then used in a legacy SD/miniSD/microSD host, issues and
problems may occur. File system incompatibility, data corruption, and potentially you
may actually lose the data/pictures. In addition, if these non-compliant
SD/miniSD/microSD 4GB cards are inserted into a legacy SD/miniSD/microSD host
device, the host device may not recognize/utilize the card as 4GB, and it instead may
read as a 2GB card. If the SD/miniSD/microSD 4GB card does not have
SDHC/miniSDHC/microSDHC on it, it is not SD 2.00 compliant.
More SDHC, miniSDHC, microSDHC compatible devices are expected to be available in
2007. To ensure compatibility, look for the SDHC/miniSDHC/microSDHC logo on cards
and host devices (cameras, camcorders, etc.)
Compatibility with SDHC/miniSDHC/microSDHC
4GB:
4GB SDHC/miniSDHC/microSDHC cards can only work
with SDHC/miniSDHC/microSDHC compatible host
devices. To ensure compatibility, look for the SDHC,
miniSDHC, microSDHC logo on the packaging. Please
check with your device manufacturer for their
current/future supported SDHC/miniSDHC/microSDHC
devices.
Helpful Tips when buying 4GB SDHC/miniSDHC/microSDHC cards
1. Please check if your host device accepts SDHC/miniSDHC/microSDHC cards
a. SDHC/miniSDHC/microSDHC logo may appear on packaging or manual
