How to fix ACL errors in diskutility
If you try to repair permissions and get a bunch of acls found but not expected.
To fix this some chmod commands need to be executed in the terminal.
Essentially open up a terminal and do the following:
cd / ls -le
Look at the Applications and Library folders in the listing and you should see they have specific ACLs. On one of my machines the Applications folder had 2 and the Library had one. On the other both had just one.
To remove these ACLs do the following:
sudo chmod -a# 0 "/Applications" sudo chmod -a# 0 "/Library" # etc...
If you had more than one on either directory you can execute the same command until they are gone.
How to DoD 5220.22-M secure wipe a disk
If you need to trash a disk its always smart to first erase all your data in a way others cannot recover it easily.
This script is a nice way to wipe it on a DoD 5220.22-M compatible way.
!/bin/sh if [ -z "$1" ] then echo "Usage: $0 ad1" exit fi doExit() { exit $? } trap doExit SIGINT confirmed=0 for n in 1 2 3 4 5 6 7 do if [ -c "/dev/$1" ] then if [ "$confirmed" -eq 0 ] then echo "Erase /dev/$1 ?" read -e confirm fi if [ "$confirm" = "yes" ] then confirmed=1 /bin/dd if=/dev/urandom of=/dev/$1 bs=8b else echo "Be careful!" exit fi else echo "Device not found!" exit fi done
How to determine the partition sizes of your disk for FreeBSD usage
Partition sizes
First of all, what I mostly do. I press A for the default partitions and then raise them. Below are some default sizes who are advised.
| partition | mountpoint | size | SoftUpdates | my size |
|---|---|---|---|---|
| a | / | 1GB | N | 1GB |
| b | SWAP | 2-3x RAM size | - | 2x RAM size |
| d | /var | 512MB to 4096MB | Y | 5GB |
| e | /tmp | 1GB | Y | 1GB |
| f | /usr | Rest of disk (at least 8GB) | Y | Rest |
For the root partition it might be smart to keep track of how large the kernel is.
This size was a default of 512MB but this is too small to install 2 kernels (kernel and kernel.old).
Another thing is the /tmp partition, this defaults to 512MB, raise it to 1GB (for tar / gzip etc)
How to backup from a Western Digital Sharespace to another Sharespace
There is a newer version of this script available here.

Lately I've been busy with making a backup script to automate the backup of a WD Sharespace drive.
This script has been made to backup between two Sharespace drives.
The script works quite simple. In a endless loop it keeps on running when you start it to the background with: ./backup.sh &
It scans for the shares on your master drive and it will Rsync it to your slave drive on the share backup.
Put this script on your slave drive in /root/backup.sh
If you decide to modify this script please leave my name in the script.
