I don't understand what has to be written to disk if there is no activity. I will try to boot with ext2, but if the guilty is ext3, then it would be a significant drawback of ext3. I am still convinced that something is not right but if it is the way ext3 work (hd activity without other activities) then I wil have a look at other journalized fs. > > It shouldn't result in "a lot" of hd access - might just make the led > flash for a fraction of a second (short enough to make me wonder whether > I imagined it....). Yes it is not a lot but it is enough to keep the HD awake and then limit the battery autonomy. > Mounting filesystems with "-o noatime" helps a little bit - but might > cause problems for programs tat rely on atime on files (e.g. mail > notifiers, popularity-contest and the like) Yes. I have added the noatime option but without significant change. Most app don't care about atime. Christophe > HTH > > -- > Karl E.
