I currently have a single 500gb drive in my Duo which is full. I'm going to replace it with 2x 2Tb drives. Can I put the 500gb drive in an enclosure and access the files on it ?

Possible to read the data, but it's not recommended to do this. It isn't easy to read it using a Linux machine, but it can be done.

Be sure to choose disks from the HCL.

I'd suggest you do the following:
1. Backup all data (put one of the new 2TB drives in an enclosure an backup to this).
2. Verify backup is good
3. Upgrade to the latest RAIDiator (currently 4.1.7: http://www.readynas.com/RAIDiator_4_1_7_Notes) if you haven't already
4. Do a System > Config Backup
5. Power down, remove the 500GB disk. You can put this drive back in the NAS later if you need to.
6. Put the other 2TB disk (not the one from the USB enclosure) in the NAS.
7. Factory default: http://www.readynas.com/forum/faq.php#How_do_I_reset_the_ReadyNAS_to_factory_default%3F
8. Restore Config Backup
9. Restore data from backup
10. Remove the disk from the USB enclosure and hot-add (add it to the NAS while the NAS is on) it.
