[plug] error trying to boot into ubuntu 10

[Phillip Bennett]

Hi David,

>From reading the log you posted, this part seems the most important to me;


[  490.196216] ata3.00: status: { DRDY ERR }
[  490.196219] ata3.00: error: { UNC }
[  490.198376] ata3.00: configured for UDMA/133

(media error) <F>
[  494.543507] ata3.00: status: { DRDY ERR }

From, this you can see the DRDY ERR  (Drive Ready, Error) and the UNC error
(UNCorrectable error) which has meant physical errors for me in the past.
This is also stated as a physical error at
https://ata.wiki.kernel.org/index.php/Libata_error_messages.

I can see the error on the second last line there says "media error".  It
looks to me as though it gets the error and resets to try again, only to hit
the same error again, and does this for a little while.  I think this is
definitely a hardware error that will need fixing.

I fixed mine by formatting the drive and having it mark the bad sectors as
such.  I don't really trust bad sector mapping that much, so would recommend
a replacement.

Hope this helps,
Phil.
