Buffer I/O error on device sdc1
I have an external Hard drive connected to my Ubuntu 12.04 machine via USB.
This morning, I saw some messages on the monitor as follows:
Buffer I/O error on device sdc1, logical block 50132671
[... and more]
This is not the first time I have seen this message. The first time I saw these messages, I quickly detached it from my Ubuntu machine and hooked it up to my laptop running on Win 7 Pro so that I could run the "error-checking" tools over it. It's a big volume disk so it took more than half a day to finish the checking and the result was good.
So I'm puzzled as to why I still receive these messages from Ubuntu.
Any help would be greatly appreciated.
