sha256sum a dvd
CentOS-6.9
I am trying to verify a locally created dvd. I am using sha256sum in
this fashion:
sha256sum /dev/sr0
Which gave this result:
sha256sum: /dev/sr0: Input/output error
So I tried this:
sha256sum /dev/cdrom
Which, after some time, also produces:
sha256sum: /dev/cdrom: Input/output error
What does this mean and how do I fix it?

io_uring cause data corruption
...st case:
* Linux 5.7-rc3 (with the patch from previous mail)
* samba-4.12.1
* gcc-9.3.0
* liburing-0.6
* glibc-2.30-r8
=================================
Test 1)
Copy 10 10GB files.
1) ddrescue -s 10G -v -f /dev/urandom 0.bin
2) for((i=1;i<=10;i+=1)); do cp --reflink=always 0.bin $i.bin; done
3) sha256sum *.bin > sha256sum.txt
4) Windows 10, file explorer, copy the 10 files to a local disk D:\test\
5) Verify local files in D:\test with sha256sum
6) sha256sum was correct.
7) redid step 4 and 5. Now sha256sum was wrong, but all 10 files had the
same (but wrong) csum!

centos 7 will not install :(
Please ... any info on how
to proceed???
After I made sure it had the correct sha256sum,
and after I burned it to DVD, and and dd'd the DVD
back to a temp file and again checked the sha256sum
of the temp file, all was OK. Same sha256sum.

the DVD.
I got a message that it was not using VNC,

Using sha256sum instead of md5sum for package checksums

http://en.wikipedia.org/wiki/Collision_attack
Recommendation from the US-CERT concerning MD5SUM hashes:
http://www.kb.cert.org/vuls/id/836068
Based on the above information, the CentOS team will be using sha256sum

e-mail announcements to the CentOS Announce Mailing List.
