ur card reader is built in ? i've a problem where i insert my SDHC card, it will prompt me to format the SD card...I downloaded the driver for Windows XP from Acer official site and now it's OK!
checked already..actually Vista/ XP manage to read the SDHC card, just W7 cannot...Yes...it's built in!
I don't have any problems...like these!
Check your card protection!
