Could someone tell me why my built in (sd) card reader doesn't work? My camera memory card works in every other computer I've tried except this one. I've made sure the windows imaging acquisition is turned on in services. Don't know what else to try. Running windows xp home edition on an hp pavilion desktop. Thanks. noboat

I hope this gives you some information you were looking for

CAUTION: Do not insert or remove memory cards while the light on the reader is flashing.

Doing so may cause loss of data on the card or may permanently damage the card reader.
