I would like to know if this is an error to be worried about or is just info? And if there's a way to avoid this output. Also, when a I run 'dmesg', I have this output (if I clear with 'dmesg -c', it will appear again in the next minutes): Buffer I/O error on device sdk, logical block 0 end_request: I/O error, dev sdk, sector 0 Buffer I/O error on device sdk, logical block 0 end_request: I/O error, dev sdm, sector 0 end_request: I/O error, dev sdm, sector 0 printk: 1 messages suppressed.
