SD card reader seems to be dead

FIRST attempt to use the SD card in a different device /SD card reader like a phone, camera, printer or third party card reader. You need to find out whether there is a problem with the card or the reader is if the other device can see it access files or save files to the card and seems to be working correctly then it's probably a reader problem could possibly be drivers or the reader it's self. It could also need to be reformatted in order for your device to use the SD card. The other possibility is that the card has gone bad and then you will not be able to get it to work no matter what you do it does not take much to damage one of the SD cards.

I would check you have all the latest updates for your Vista installation as I know for some versions of Windows extra updates are necessary for exfat support.

Does the SD card read; is it accessible; in other devices?

The SD Card may be broken

The limit for SD cards for your system is 2gig, you will need to purchase an external reader, your 4gig card is a SDHC

Replace the card reader, it has died - it happens. Luckily this is a cheap fix.

No you don't need something to make your sandisk(sd) card to work when you place it in the sd slot of your computer, now if your sd card is a hc or high compacity card then it would not work because the sd card reader is not new upgraded enough to the point of reading the hc cards if its not a hc card then your sd card reader may be broken you can buy a good new sd card and more port hub to work on your computer but i would check first if it is your card not the card reader.

I would like to inform you that Acer's laptop doesn't support all kinds SD memory cards available in local market. Its not compatible with all physical dimensions of various memory card companies. So in that case you need to use EXTERNAL Memory card reader which is attachable to USB ports.

If this solution was helpful to you then please rate 100% (or FIXYA) for this solution, otherwise don't rate at all. It was my pleasure helping you.

Hi corgee, you can't copy images off the SD card unless your printer is connected to the PC.
If you still want to have access to your SD card & not use the printer you can buy a SD card reader for as little as $5.00. Your card reader would plug right into a free USB port.
