Perhaps Microsoft's KnowledgeBase site can tell you > how. I found a free tool to read a raw sector of a partition (NT Disk Viewer). Unfortunately USB Snoopy kept stopping capturing packets after a few seconds, so I was not able to see what was happening. Anyway, I goi a read error ofter a while the program seemed frozen. So I guess Windows is handling them retrying to read the sector and finally giving up. A question: If I rewrite these sectors I can fix these errors (at least temporarily). I also noticed that when the "check condition" bit is set some data is also tranferred. Is there get these partial data (e.g. with dd)?
