PARTITIONS IN USB DRIVE

[Habari]

i want to partition a usb drive in 3 bits:
1.fat 32 , here i will store backtrack linux (primary)
2.ex2 for persistent change files (primary)
3.fat 32 for windows files (logical)
i did it with acronis and now the only thing ive managed is that windows wont recognize my usb pen in ANY partition,
i tried to remove partitions with acronis but it doesnt work!
any suggestions anyone??
