Windows needs to be trained to identify CFast cards. You can train Windows in two ways:
1. Boot with the CFast Reader attached (cards do not need to be plugged in).
2. Plug in two CFast cards, and then hot-plug the Thunderbolt cable to the CFast Reader.
After either one of these training methods, Windows will continue to automatically recognize inserted CFast cards.

If you hot-plug the CFast Reader Thunderbolt cable without CFast cards installed, then Windows will not recognize cards.

These cards draw more power than the official specification. Sonnet has revised the CFAST reader to accomodate these cards. The original CFAST Reader had serial number starting with "A". Modified CFAST Readers have a serial number starting with "B". Sonnet is offering a free upgrade from A revision to B revision for customers with this issue.
