硬盘式播放器 HD300挂载问题

[FoReStTrEe]

症状：MPIO的HD300硬盘播放器，使用的是TOSHIBA MK2006GAL 20G的微硬盘，9.04下将HD300直接接到USB口上作移动硬盘拷贝数据，发现如正常U盘，能直接自动挂载，拷贝文件正常后右键“卸载”，拔下后播放器亦使用正常。后于XP系统下连接HD300，不能直接识别（未见分区，但整个盘未分区，为FAT32文件系统），设备管理器下同本机硬盘类似，可见如TOSHIBA MK2006GAL USB storage 字样，说明硬件可识别，“安全删除硬件”时无反应长时间等待，故无法正常删除硬件。遂返回UBUNTU，连接USB后无反应，fdisk -l也无反应，lsusb可见如下内容：

DigitalWay经查即为HD300，Device信息也正确

可见也正常识别了硬件，但是水平不够，看不出是什么问题，接下来该怎么办？请详细告知
