I now believe that the device state is being maintained in the kernel (Driver???) because of failure of disk to respond to host query to identify itself or to host query to report it's DMA status?? Please have a look at the error messages I had posted at http://www.sendspace.com/file/761te2 Guess I should download full kernel source and peruse the drivers code to see if and where the read-only state is being set as a consequence of no response to host's queries. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
