SDHC card isnt being reconized by my computer

Try a different / all other USB ports on the computer, and if possible, a different computer if no USB port on your computer works with it. If it still doesn't see the drive, the drive is probably not working. If it does see the device, but is asking for drivers, provide a disk with drivers that came with the reader - or check the Sigma web site for drivers that work with you OS (Windows, Mac, etc.), download and install / extract.

If it sees the device, but doesn't see the memory card, the reader may not recognize the newer, larger capacity memory cards. SD cards are smaller than 4GB in capacity, and SDHC cards are 4GB and larger. Make sure that if you're trying to read an SDHC card that the reader SPECIFICALLY says it works with SDHC cards. Most SD readers can NOT be upgraded with firmware to be able to read SDHC cards - a new SDHC reader is required.

Good luck!

uplug sound card on start up and plug back in if windows still doesnt reconize the drive the min. it pops on right side computer click on it trouble shoot it.

Newer cameras may have SDHC cards - these have a high capacity. Older computers can't read the newer SDHC cards - they can only read the old SD Cards. The SD card and SDHC cards look exactly the same. The SDHC card will probably say "SDHC" on it somewhere. Fortunately you can buy a USB SDHC card reader for a computer for around £2 on amazon. I would buy one of those. You could search the internet for "usb sdhc card reader".

This camera was manufactured before the SDHC protocol was developed for SD cards. A 'standard' SD card protocol is 2GB maximum, and that is what the camera is compatible with. I'm pretty sure the cards you are trying to use say SDHC on them, right?

you need to search if the driver is instaled,if not go to dell.com and download the driver and this should resolve your problem.

Are you using software that came with the reader? Maybe that is the problem. Are the correct drivers installed? Check the device manager and make sure it does not show a problem device. Are you using my computer and clicking on the removable device? Does the card work ok in other computers or devices? Is your computer only USB 1.0 and the card reader requres USB 2.0? Are the USB 2.0 drivers properly installed on your computer? Try removing the software and drivers, re-boot, and just install the drivers and not the software.

your SD might be and SDHC or larger that 4GB. try to use a FAT32 formatted SD, no bigger than 4GB

some stuff they say is plug and play but i would go to the support site for the cam and try to find a driver for it and once you find it install it on your computer some stuff they say is but sometimes it really doesnt work without a driver if you dont already have the driver heres your cam and the drivers on this page http://www.radioshack.com/product/index.jsp?productId=3046311&tab=support

Try uninstalling the device and searching for new hardware. If that doesn't work try installing the latest drivers/firmware.

Older model printers won't recognize high-density memory cards.

2 gb is probably the largest to be used in your printer.
