win7 sd烧录的问题

啊权

今天想了解下如何烧写软件。由于win7 dnw使用不方便，因此我采用了sd卡烧录。但是我发现烧录一直走不下去，希望大家能帮我看看是什么问题。采用的烧录方法是论坛中提到的《210ii 更新 android4.0 inand rom的笔记》（http://www.bbs.9tripod.com/forum.php?mod=viewthread&tid=20667）
在执行这两个命令时   sdfuse flash kernel zImage，   sdfuse flash system x210.img。板子会被挂死。如下：
x210 # sdfuse flash system x210.img
[Fusing Image from SD Card.]

ptn 1 name='kernel' start=N/A len=N/A (use hard-coded info. (cmd: movi))
ptn 2 name='ramdisk' start=N/A len=0x300000(~3072KB) (use hard-coded info. (cmd: movi))

ptn 4 name='userdata' start=0x10D5DA00 len=0x15E8B600(~358957KB)
ptn 5 name='cache' start=0x26BE9000 len=0x6751800(~105798KB)
ptn 6 name='fat' start=0x2D33A800 len=0xBE083000(~3113484KB)
Partition: system, File: /sdfuse/x210.img
Partition1: Start Address(0x2000), Size(0x760c00)
reading /sdfuse/x210.img
268435456 (0x10000000) bytes read
一直停在上面的一句话上。以为是SD卡的问题，换了一张sd卡，结果还读不到文件：x210 # sdfuse flash system x210.img
[Fusing Image from SD Card.]
[Partition table on MoviNAND]

ptn 2 name='ramdisk' start=N/A len=0x300000(~3072KB) (use hard-coded info. (cmd: movi))
ptn 3 name='system' start=0xB11E00 len=0x1024BC00(~264495KB)
ptn 4 name='userdata' start=0x10D5DA00 len=0x15E8B600(~358957KB)
ptn 5 name='cache' start=0x26BE9000 len=0x6751800(~105798KB)
ptn 6 name='fat' start=0x2D33A800 len=0xBE083000(~3113484KB)

各个大侠能帮忙看看为什么吗？
使用的操作系统是win7（不过这个应该和使用SD烧写应该没有关系），SD卡格式化为fat格式，同时 zImage 以及 x210.img使用的是光盘提供的。只是为了体验下如何烧录。
望各位大侠指点。

终于找到原因了。将SD卡格式化为FAT32,烧写就可以成功了。但是还是不明白为什么有的兄弟可以用FAT有的不行呢？
