I have a Synology NAS that I've set up with RAID 1. The device is set up with two drives, both the same size (i.e. 500 GB each), formatted in ext3, as a RAID 1 volume (i.e. even though the total capacity is 1TB, I effectively only get 500 GB).

In the case of a device failure where I can only access one of the drives, how can I recover my data? The solution I'm looking for is something like: 'Put the working drive in an enclosure, and use <some software> to recover your data.'
