You're saying that the device fails to carry out WRITE commands correctly and yet doesn't report any errors. This makes it nearly impossible to tell when an error has occurred, let alone figure out the reason for the error. We're pretty much reduced to guessing. For a start, you should post the entry in /proc/bus/usb/devices for the player. You should also check the output from dmesg to see if there are any errors or warnings in the kernel log when you plug in the device or when you write to it. By the way, are you careful always to unmount the player's filesystem before unplugging it? Alan Stern ------------------------------------------------------- Using Tomcat but need to do more?
