That's entirely the point. If we stay silent we get complaints about not telling people that there's something wrong. If the error messages are not excessive and scary, then people don't report them and so we never hear about problems that are occurring. > I can understand why some > people might misinterpret those messages and assume it's a hardware problem. Quite frankly, the biggest problem we have *always* had is that people don't bother to read their log files when something has gone wrong or selectively quote the logs when reporting the bug. This is the primary reason for the "how to report a bug" FAQ entry asking for the *full logs* to be posted in a bug report. Removing error messages because they are "noisy" is not the answer. Verbose error messages (especially corruption reports) are there mainly for the benefit of the developers, not the user. The user needs to know when a corruption has occurred, but we need to understand the what, how and why of the issue. It's far better to scare users by dumping all the relevant info into the log when an error occurs than to be sitting around scratching our heads going "WTF?" like we are right now because there isn't enough information in the logs to have even a basic clue of what is going wrong...
