Matthew Dillon posted a July 16th Hammer update where he details causing a lot of write activity on a USB-connected, Hammer-formatted hard drive, and then yanking the USB connector out. Apparently, doing that 50 times over didn’t even faze Hammer. (Of course, be careful trying that with power.) He’s been committing a lot for Hammer, along with Sascha Wildner and Thoman Nikolajsen. A side benefit is that the Hammer work has exposed some issues in CAM.
