Looks good to me. I'm still sticking to the (assumption|hypothesis|foolish fantasy) that even cards that do not support partial block writes will still support 512 byte writes - mainly because I just don't see those ASICs in the el-Cheapo card readers being capable of doing the advanced buffering to convert 512 <-> 1024 or 2048, and hopefully one of these days I'll find a card to prove that. Until then, I don't have a leg to stand on, so I'll quietly hang back. Jordan -- Jordan Crouse Senior Linux Engineer AMD - Personal Connectivity Solutions Group
