I had a Toshiba USB stick that was much better - it had a Public partition, which was visible when you inserted the drive, and a Private partition that became visible (and accessible as a normal drive) when you unlocked it.
So I think that the SanDisk SecureAccess is only suitable for files/folders that you're happy to copy manually - it's no use when you have huge folders that you want to synchronise daily, using FreeFileSync or rsync or anything else. The only automated copying it supports is making a backup, from the USB drive to your PC. Unfortunately I don't think it's possible - the SanDisk SecureAccess 'vaults' are only accessible via very limited interfaces, through their software application.
