Hi Donal, On Fri, 13 May 2011 17:33:07 +0100 you wrote: > embedded platform running the 2.6.8.1 kernel Did you mean that? Or was it a typo and should say 2.6.38.1? If the former then somebody will reply saying please use something slightly approximating a modern kernel. When you say it happens on "various brands", do you mean it happens on every stick you've tried, or only on some? If the latter, is there a pattern? Just as a random thought, does it happen if you substitute some other USB mass-storage device like a hard drive? That would tell you whether the slow write problem of flash drives is relevant (though your data rate doesn't sound excessive). I'm sure the knowledgeable folks here will have more useful suggestions.
