This is a request to read 8 sectors (4k of data) from a point which is 128-sectors from the end of the device. The device never responds to the command, and we go into error recovery. We recover, we retry, and we keep getting the same response. This looks like a pretty broken device. Any idea what the real sector count is? Maybe take a look at the partition data reported by Windows? Matt -- Matthew Dharm Home: mdharm-usb@xxxxxxxxxxxxxxxxxx Maintainer, Linux USB Mass Storage Driver P: Nine more messages in admin.policy.
