MyMPx.org - Help with generic Mp4 player -trouble formating/configuring

I purchased generic 8 GB Mp4 player from sourcinggate for $63 CDN including taxes, shipping & handling. When I attached the Mp4 player to my CompaqPressario (XP operating system) the Mp4 players was formatted to FAT32 and I lost 4.2GB. To top it all off, my computer does not recognize the generic Mp4 player. I have to go into Devices, Action, click on USB controllers and scan for hardware changes so that my computer recognizes the Mp4 player. I have managed to download a lot songs onto my Mp4 player. Now it there any way I can get back the 4.2GBs I lost when my pc automatically reformatted the generic Mp4 player? Also is there anyway I can configure or format the generic Mp4 player so that my computer automatically recognizes it. I have searched www.download.com for firmware, drivers, software etc but can't find anything. I have attached a link of the product I purchased on sourcinggate.

Widescreen Portable Mp4 Player 4.3-inch Touchscreen FM 8GB - $63.00 - Buy from China

Any words of advice would be appreciated.
