Alan, Thank you for the answer about the error. This particular drive has a separate power supply, so there is a possibility that the drive writes the cache out either as it senses its removal from the USB bus or as I turn off the power on the power switch (it may be a "soft switch"). And if the drive received its power from the USB bus I would be a bit more concerned. In any case, if it is the cache of the actual disk drive that is generating the error, I feel better about it than some cache in Linux not being flushed properly. I will go back and capture just this error again, then I will try to enter this as a support issue with the Iomega people, but quite frankly I think that I would probably not get as far with them as I have with you. ;-) Thanks again. md -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
