Is there any ext3 feature that would cause disk layout to vary if one were to delete all the files on disk and then rewrite them in the same order? We've been doing some simple read/write file system tests in our lab that sometimes result in short delays being distributed throughout several files. As long as we don't re-wipe the drive, these delays occur at repeatable offsets within the affected files, suggesting disk seeks at the affected locations. To my understanding, deleting a file should mark all the data blocks as free. Thus, any previous disk state should no longer affect files that are written thereafter. Is this correct?
