How to see other partitions using the Terminal Emulator and mount them?
The Android's linux kernel would not have the SATA/IDE hard drives drivers installed into the kernel, all it can see is flash cards MMC, understands ext3fs and ext4fs, vfat filesystems so the answer to the question is no you cannot see other partitions outside of the domain of Android itself! What you can do though is this, build a new linux kernel with the appropriate drivers installed in place, then the mounts would work :)
