## Description
```
> ls -l /home/blitzkrieg/file.iso
-rw-r--r-- 1 root root 4625235968 апр. 14 23:43 /home/blitzkrieg/file.iso
```
Then i burned this iso with Xfburn on DVD-RW
And then i try to get dd image:
```
dd if=/dev/sr0 of=/home/blitzkrieg/newfile.iso bs=1024k
ls -l /home/blitzkrieg/newfile.iso
-rw-r--r-- 1 root root 4625543168 апр. 15 14:39 /home/blitzkrieg/newfile.iso
```
newfile.iso is larger than original iso 307200 bytes. It contains 307200 of zero!
I've try this three times and every time i got the same result.
Than i try burn iso with brasero. The first try was succesfully.
