The error message (repeated 3 times) I read from the screenshot is:
kernel: [ 3009.877308] sd 9:0:0:0: [sdb] No Caching mode page present
kernel: [ 3009.877311] sd 9:0:0:0: [sdb] Assuming drive cache: write through

This reminds me of bug #733565 [1], which is about a request to silence 
these error messages.
I have seen similar messages and they seem to be totally harmless and 
have nothing to do with hardware failure.

Best regards,
Andreas
