If this problem occurs then your ML648B needs to be formatted.

1. Connect your ML648B to your computer with Windows XP or later.
2. By default your computer will recognize ML648B as GPX MTP Device. Press the POWER button from top of your ML648B, to change it to USB mode connection. You will also see USB on the screen of ML648B.
3. ML648B will now mount 2 drives, one as Tools (as CD-Drive) and second as Removable Disk (Drive) – under My Computer on your Windows Desktop.
4. Right click your mouse and then select the Format option. When the Format Removable Disk window appears select the Start button to start formatting your MP3 player. - Tha Mp3 Doctor

The computer recongize it as a removable disk.
plug in your mp4 player
click start
click computers
click removable disk
formate the disk
copy and paste you songs.

u might have to reformat it because mine did the same thing and sombody told me how to reformat it all u do is plug ur mp3 into ur computer with ur usb cord then go to a folder called 'my computer' then there should ba an icon that looks somthing like an mp3 and if u dont see it at first give it a few minuets then when it dose show up it should have the name of what ur mp3. RIGHT CLICK on the icon then click on FORMAT and it should reformat it.It might not work though oh and if the name of ur mp3 isent there but the icon is and were the name of ur mp3 should be it will say something like MTP device like it did 2 me when i tried to reformat mine.If that dont work u could try to reset it by holding the power button for 10 secends.Those might not cause neither 1 did 4me.good luck!!

Hi, you can try to upgrade the player's firmware, you can download it from the RCA Website (http://support.rcaaudiovideo.com/downloads.aspx?product=187), the firmware it's the second app listed.
If your computer doesn't recognize the player, you'll have to turn it off and keep "PLAY" pressed for 10 seconds while connecting it to the USB port, then update the firmware.

format the drive and use "safely remove hardware" function to diconnect it from the usb from now on

the best solution is a lawyer and a lawsuit to the nextar company.....

Change the MODE and try formatting again.

SETTINGS>MODE or USB.


Best of Luck.
