I tried with other external hard drive and found an conclusion. The LS-CHL doesn't work with Prolific chipset external hard drive. LS-CHL can see the drive but can not mount the drive for unknow reason, that cause the LS-CHL not able to format the external hard drive and it just went coo coo. Maybe I am newbie or what but for some reason, when I used the LS-CHL to format external hard drive with EXT3, the external drive can not be read on XP. Don't get me wrong, I used ext2if/ext2fsd and non of them will work with the external drive just got formated with EXT3. So I went the other way, I formated the external drive with EXT3 partition by using Acronis Disk Director to see if it will work. The external drive can be read/write on my pc after formated by Acronis Disk Director and it is EXT3 format, but the external drive can not work with LS-CHL, LS-CHL does see the external drive but can not mount. Does LS-CHL using some speical ext3 format or what?
