Hi folks,
Could everybody with a cd-rw drive try the following program, and see if works (ie produces lba output) or if it complains about I/O error (and dumps a kernel message saying so, please send that too btw).
axboe@burns:~/proggy $ sudo ./trigger_rahead /dev/hdc /dev/hdc: trigger LBA 1024, ra LBA 1050
Thanks
