I dont know how to put music on my lexar!!!!!!

Don't know much about the Samsung phone; Can you put music on the 1 Gb memory card from another source (like a computer) and have it recognized by the phone?
Does the phone require music in a particular format? For example, if the phone recognizes .mp3 music files, but all your music is in Ogg Vorbis (.ogg) files, you will not be able to play them on the phone.

1) Find the Samsung phone manual (online?) and see if it requires music files to be in one format, or another.

2) Try loading music, in the proper format, from different sources onto your memory card.

Best of luck!

It appears in My Computer as a Removable Media only if it has a card in it. If it still doesn't appears with a card , even in another pc, then it's faulty, get a new one

To connect the SD memory card to the computer you need a USB memory card reader. Plug the SD memory card into the USB card reader and then plug the card reader into the computer's USB port.
The computer will see this as an external memory card, you can then click on this memory card (it maybe the D or E or F drive) and select the music files from your computer then copy and paste your music files to this memory card. I presume the music files you need to copy are MP3 or MP4 files.

Hi If your card is SDHC version is possible that you card adapter doesn't support it, you have to try another one.

Well this can be a nuber of problems one could be if you put them in the right folder and you can use windows media player and sync music insted of drag and drop

You should be able to just push it into the multicard reader on the right hand side of your Acer One.

You just need to connect the Lexar 1Hb to the USB port on your computer and let the computer recognize it and then after that double click Mycomputer and you should see there the Lexar , just double click on it and now you can copy and paste music from your computer to the Lexar...

Format the card in the camera and start over

You need to change your USB Port... try the back of your computer. Or you need a firmware update.
