Found this on BetaNews.com this morning and it just become active.
Get O&O DiskImage 5.6 Professional free for next 24 hours only. No, it's not the latest version (that would be version 6 which adds some features and you can buy from the same location for 50% off).
Both the 32 and 64 bit versions are available for download.
Note that you will need to create an account on the site and activate it before downloading.
Anyone have any experience with this product? As compared to, say, Macrium?
