Hi List,
I find somewhere in the Net that to check the goodness of CD we can use
dd if=/dev/cdrom of=/dev/null
If the o/p is without any errors then CD is fine.
I checked this with a CD i have. I got the following o/p
[root@snmoorthy root]# dd if=/dev/cdrom of=/dev/null
dd: reading `/dev/cdrom': Input/output error
2392+0 records in
2392+0 records out
CD is partially written and I can understand that reading beyond that
gives I/O error. While giving following command with blocks
[root@snmoorthy root]# dd if=/dev/cdrom of=/dev/null count=2392
2392+0 records in
2392+0 records out
Here I have specified the blocks in "count" parameter. My question is,
is there any way to find the bytes currently used in CD so that I can
specify in "dd" command.
TIA
Moorthy
