Hi! I have an Acer Aspire 7551-3650 laptop, and just in the last few days it has stopped recognizing an SDHC card when it is inserted in the SD slot. I went to the Acer website and downloaded the latest card reader, but that did not help. I would have thought it was a problem with this model not recognizing an SDHC card, but it has been able to read it without any problem up until now. Any suggestions would be most welcome!
