Hi, % dd if=/dev/sda count=1 | hexdump gives all zeroes. If I increase count, occasionally some data shows up which isn't meaningful ascii, but mostly zero. The same flashdisk mounts fine on a known-to-work platform, and shows the same output for the above command. Also below is what I get from usb-storage when I type the above command on the platform that fails mounting. Do you have a suggestion for what to check? Since the drive mounts fine on a host controller that works, I guess it's not the partition table I need to inspect?
