How to download music onto a lexar mic...

hi, it should be in my computer, then sd card should be list of drives on the acer, if not you may need the updated drivers or it is broken, i know this because i have 2 newer acer notebooks, one the driver updates fixed. the second one,the chipset controlling the card reader,usb,touchpad, keyboard,are all dead.sent it to the factory and they want 450.00 flat rate,for repair for this problem. if the usb ports work on your pc, consider an external card reader,if the usb ports don't work, get an pcmcia cardbus usb. or xpess card whatever your acer is equipt with. here is a link for acer drivers. hope this helps you folkshttp://www.acerpanam.com/synapse/forms/portal20.cfm?website=AcerPanAm.com&siteid=7117&areaid=2&formid=3394#results
