I have scoured the internet and although I have seen topics that start to 
address this they get sidetracked and end up somewhere else.  My desire would 
seem to be simple:

After I 'chroot /mnt/USB0' to a USB ext2 thumb drive that has the 
Technologic-supplied Debian on it, I cannot see the information on the 
'original' root of the flash drive (/dev/mtdblock/1).

How do I mount the flash drive or see it from the new chroot?

My principle motivation for needing to do this is that I have bad blocks on my 
flash drive (some of which can be seen by 'dmesg' after bootup) in the flash 
drive area used by TS-Linux.  The utilities I would need to address this (like 
'badblocks') are not found in TS-Linux, but are available in Debian.

By the way, if I use the supplied 'loadUSB.sh' to effect a boot to Debian it 
often hangs on the way there--possibly due to the afore-mentioned bad blocks on 
the flash.  If I can't identify and sequester those areas, my TS-7250 will 
always be problematic.
