# E-scripts on hard disks (partitions, parameters, etc).

# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.
#
# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my
# .emacs.
#
# Note 7: if you see a strange command check my .zshrc -- it may
# be defined there as a function or an alias.
#
# Note 8: the sections without dates are always older than the
# sections with dates.

# Error: The partition table on /dev/hda is inconsistent. There are
# many reasons why this might be the case. However, the most likely
# reason is that Linux detected the BIOS geometry for /dev/hda
# incorrectly. GNU Parted suspects the real geometry should be
# 16067/16/63 (not 1008/255/63). You should check with your BIOS
# first, as this may not be correct. You can inform Linux by adding
# the parameter hda=16067,16,63 to the command line. See the LILO
# documentation for more information. If you think Parted's suggested
# geometry is correct, you

<T_VoiD> edrx: badblocks or e2fsck -c . you could use a file list from
the sector, but the value has to be divided depending on the block
size I never know, so better create the list with badblocks + e2fsck
-l (or use directly e2fsck -c)
