Don't hit me, but i tried dumb thing:
# sync
# perl -e 'print "B"x4000;'
# sync
# debugfs -R 'logdump -ac /tmp/output' /dev/hda6
# vi /tmp/output
But i didn't find any patterns which look like four thousand equal characters.
I guess, data will be encoded bevor written to disk. Why? How it is done?
Maybe anyone can tell me quickly, how data is handled (encoded etc.)
before written to disk (i know this doesn't circumvent taking a good
book about filesystems/ext2 some day...)
bye
