[colug-432] No I/O Errors?

[Thomas Cranston]

I returned my HDD for replacement, and am now running the original
drive that I was getting I/O Messages on when I ran md5sum.

I just downloaded Linuxmint 14. Ran md5sum. md5sum matched No error messages.

1520: ~/Linux_Distros/mint$ md5sum linuxmint-14.1-cinnamon-dvd-64bit.iso
1b103578411b421cc012cddf3253e32c  linuxmint-14.1-cinnamon-dvd-64bit.iso
1520: ~/Linux_Distros/mint$

Looked into /var/log messages and dmesg.

I do not see anything that indicates I/O errors.

Am I missing anything?

Back on Dec 2 2012 when I got error messages after running md5sum, I
may have downloading via wireless to my router. Don't remember. This
time I connected with Ethernet cable.
