See here: http://wl500g.info/showthread.php?t=14128

With the information in that thread you can mount the external disk with Linux, access your data, umount and put it back to the WL700gE without loosing your data. No writing on the disk is needed (except maybe on the file system itself), therefore minimising the risks of loosing something..

If we can make a solution that combines the tricks to get a PC/WL700gE mountable disk from an existing WL700gE External disk without loosing data... maybe... If something else comes to mind I will post it here... But don't count on it, my major concern is getting my external disk from my WL700gE to my Linux system (back is not important)...
