Thanks for quick response, I do not mean user use fdisk command on CD/DVD. However, whenever using 'fdisk -l' command, the system will access each first sector on each SCSI device (including CD/DVD on it) and the DMA transfer on blank CD/DVD will not return any data.
Shouldn't the drive return error status in this case?
The timeout is detected and error handler will be called.
But user may also run 'hdparm -t' or even 'dd' with offset on a drive. Have you tried your workaround with those?
Using PIO on some first sectors will avoid the issue.
