The memory card reader locks up? Why?
Many card readers were created before SDHC technology became available and are not capable of working with the new format. For example, a memory card reader that was made in 2002 can read a 1 GB Secure Digital (SD) card, but cannot read a 16 GB SDHC card. To use your higher capacity memory card without locking up the computer, do one of the following:
- If you are using the card in a camera or other device, you can attach the device to the computer using a USB or FireWire cable. When connected, most devices appear in Windows as a Removable Disk and can be used in the same way as the card reader.
- Buy a USB memory card reading device that plugs into an open USB port. Make sure the USB device can read SDHC. These devices can be used in any computer that has a USB port.
