Music files transferred thru card reader play poorly

[serendipiti]

Hi!
I have a Nokia 6233.It came with a built in 128mb MicroSD card.Recently i purchased a Transcend 2GB MicroSD card along with a card reader. Problem is when i transfer music files thru bluetooth(through nokia audio manager) they play ok on the phone but when i drag and drop files on the music folder of the card thru a usb card reader the files play with a garbled noise.I don't know what to do as transfer through bluetooth to fill up a 2GB card will take ages and i really want to use the faster way of using the card reader.Please suggest a solution!

Its the wierdest problem I ever seen...
Make sure your card reader is not damaged... or faulty...
Try formatting your card too.
Get a card reader of a friend and try transferring file through that and check if they play right.

a faulty card reader/cable is all that i see. why don't you directly connect the phone thru data cable and then check in mass usb storage mode?

Thanx mates for ur replies. It was the card reader that was causing the problem...replaced it...working like a charm.
