Author’s Note: While most of this piece discusses configuration options for any operating system Apache supports, some of the content will be Unix/Linux (*nix) specific, which now includes Macintosh OS X and its underlying Unix kernel.
One of the many pieces of the Website puzzle is Web logs. Traffic analysis is central to most Websites, and the key to getting the most out of your traffic analysis revolves around how you configure your Web logs. Apache is one of the most — if not the most — powerful open source solutions for Website operations. You will find that Apache’s Web logging features are flexible for the single Website or for managing numerous domains requiring Web log analysis.

Before starting, the MBR included in the files are incorrect, for the mbr, please use the link at the bottom of this post.
What is this
These are backups of a brand new, never booted, Western Digital MyBook World Edition 500GB (single drive not II) Since the only way people as of creating these have to restore a bricked MB WE is to rebuild a Debian edition using the sources available which takes a long time and is confusing to many. I decided to open up an brand new one and rip the hard disk images, partition table, master boot record, and complete file systems keeping all permissions. The Firmware is 01.01.18. I used System Rescue CD, to obtain access to the drives. Running PartImage fails, so I used DD.
| Name | Partition Type | Partition Size | File System | Mounted On |
|---|---|---|---|---|
| sda1 | ext3fs | 2.80 GiB | /dev/root and rootfs | / |
| sda2 | swap (v1) | 101.98 MiB | ||
| sda3 | ext3fs | 964.84 MiB | /dev/md3 | /var |
| sda4 | ext3fs | 461.89 GiB | /dev/md4 | /shares/internal |
This was acquired by running “dd if=/dev/sda of=sda_mbr bs=512 count=1″
You would restore this by “dd if=sda_mbr of=/dev/sda bs=512 count=1″
- Partition Table -
This was acquired by running “sfdisk -d /dev/sda > sda_ptable”
You would restore this by “sfdisk /dev/sda < sda_ptable”
- BitByBit Disk Copies -
(These are exact copies of the partitions and will extract to be the partition size)
These were acquired by running “dd if=/dev/sda1 | bzip2 > sda1_image.bz2″ on each partition where sda1 is sda1-sda4
You would restore this by “dd if=sda1_ima of=/dev/sda1″, however since I piped them out as bzip2 files you will need to pipe in the std out of bzip into dd. I can’t remember the command line options at this time.
WARNING: SDA4_IMA.BZ2 will extract to 461.89 GiB, as each file will extract to its original partition size.
- File System Dump Containing Permissions -
(These contain the file system for each partition while keeping full fs permissions)
This is acquired by mounting each partition as read-only as ext3 and tar/gzipping them with permissions. I can’t quite remember which command options I did at the time.
You would restore these by mounting the partition and just extracting and writing over your files in your partition as root. You may need to delete other files you have created that are not in the archive, especially in your init.d.
You can also grab the files you may have corrupted individually as this is a copy of the files and structure. When mounting the FS you need to specify the type as ext3. Auto will detect the raid configuration and is unable to mount.
Since I am not positive about storing these files and Western Digital’s EULA, I posted them on rapidshare.
Please mirror and post here. Posting back to rapidshare is pointless unless you reencode them in another compression format, as once a file is deleted, so is it’s hash.
WD_MYBOOK_WE_500GB_FILE.7z (59MiB)
WARNING: These expand to the 500GB, mostly of empty space.
WD_MYBOOK_WE_500GB_IMA.7z (57MiB)
I forgot to include SDA3_IMA.BZ2… please get it from here SDA3_IMA.BZ2 (19k)
(Since wikidot tells browsers this is a text file, please save the file directly from the link or use wget to download it.)
bzip2 -cd SDA1_IMA.BZ2 | dd of=/dev/sda1
-c is to force stdout and d is to force decompression. Then it is just passed to dd that writes bit by bit into the partition.
I can tell you that both files (MBR and SDA1_IMA.BZ2) did work smoothly.

Macintosh OS X
Step1
Start your computer and wait for Mac OS X to load.
Step2
Choose ‘About this Mac’ from the menu located on top left corner of the screen.
Step3
Open ‘Activity Monitor’ from the Utilities folder.
Step4
Click on the System Memory button located at the bottom of the window. You will know the amount of RAM installed and the current usage.
Step5
Note that RAM testing in Mac is not very common as the system is comparatively safe.
Step6
Use the software memtest 86+. Download the free memory testing software memtest 86+ from Microsoft (see link below). It runs on most of the configurations. You need to download the diagnostic and read the details.
Step7
Testing the RAM with this software in the first phase that will take less than 30 minutes.
Step8
Reboot your computer with the disk or CD-ROM on which you installed Windows Memory Diagnostic. You will view the interface and the first test pass will be conducted. This will be followed by a second test until you exit. It will identify if there is hardware problem of RAM or the motherboard.
Step9
Use the ‘Rember’ test if you are using a lot of graphics. This is more of an auto-run test after you launch it. In a few minutes you can view the results in the Rember Log screen.
