iPod problem!

I have this iPod not a apple make but a china made one about 2gb space, FM, Video playback, MP4 etc. Now the problem is i dont have any user CD but a manual & some cables, now i used this directly as a flash drive put mp3 files in it, deleted some unknown files from it & played the songs itworked fine for 2-3 days now when i put this to my machine it gets detected but as amemory drive i can even access this drive is my problem. Its being detected as a 1 mb fat file, i cant format it.
There are no songs i copied in it but the sample mp3 & video only. I can see my folder in which i copied the songs.
Now what can i do to correct it?

If its possible try to find the web site of you player and download the latest firmware and also the manual it will tell u steps to do a complete format try it.

This manual suggests me to format it with FAT file system but my windows formatting tool dont have that option. I think the disk is currupt.

Hey my friend...Try to format it from ipod itself...it will solve your problem....dont format it through your PC....it will delete your supporting files....
