I had noticed these boot time messages in /var/log/kern.log for some time now: Buffer I/O error on device sr0, logical block 49150 sr 0:0:0:1: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK sr 0:0:0:1: [sr0] Sense Key : No Sense [current] sr 0:0:0:1: [sr0] Add. Sense: No additional sense information .. and further on: sr 0:0:0:1: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK sr 0:0:0:1: [sr0] Sense Key : No Sense [current] sr 0:0:0:1: [sr0] Add. Sense: No additional sense information end_request: I/O error, dev sr0, sector 196600 The same two sequences are repeated a number of times with different "logical block" and "sector" numbers. I could not find online documentation as to where they come from or their syntax - I could be wrong, but stuff like "Sense Key:" reminds me of scsi messages. On a hunch, I shutdown the laptop, removed the flash drive, rebooted, and sure enough they were gone. I'm guessing, but this looks like the kernel is performing some kind of sanity check on the device and does not like what it finds. Just wondering if this might have any relevance to the device slowly but surely going bad..? In any case, since this concerns only about half a dozen sectors out of apparently tens of thousands, at that rate, it looks like the flash drive will probably outlive its usefulness. Maybe the problem would eventually turn out to be the verbosity of those messages filling up the logs.
