Oh, I'm confused with another embedded device. There's no /var/log/messages.

Apparently detects the device, but cannot read the partition table (which makes me wonder what /dev/sda was, did you unplug the other disks?) That would either mean an unreadable device, or a full-disk format. But that should just work.

Next try, what does this command do (provided that your disk is still "sdb"):

MDEV=sdb /etc/mdev/mdev-mount.sh

/dev/sda is my interal disk is not unpluged

What's the output of "mount" (and "ls -al /dev/sd*" while you're at it) on those images?

And you are not using some form of multiboot, are you?

never used multiboot

Is it an NTFS disk? If not, what else?

Yes it is. and all problems starts with kernel update.
