Every few months, I like to completely blow away my Windows system and reinstall it. This is primarily because I install so much junk on the system that it just starts to clog everything up. A freshly installed copy of Windows always runs so much quicker and has that “new OS smell”!

I firmly believe that more people would do the same if it wasn’t such a pain to do! Most people figure that you simply need to set aside a full day to do the job right.

So, I’ve put together a two part checklist of things that you should do before and after you completely reformat your system to start over.

Before You Reformat

  1. Move all of your data off the computer and put it on a different system or drive. The most important folder to backup is the user profile (%USERPROFILE%) folder. This will usually back up 95% of what you want including your My Documents, music, pictures, favorites (for Internet Explorer), e-mail, etc.
  2. Backup all of the device drivers that are being used on the system and store them somewhere else. I use a freeware program called DriverMax but I am sure that there are several other good ones out there.
  3. Make sure you have a copy of all the software installed on your computer along with all of the license keys. A quick way to get a list of all installed software is to use something like Belarc Advisor. If you do not have the license keys, a program like Magical Jelly Bean Keyfinder might be of help. This includes operating system and software that you bought by download. I usually start making this list a few weeks before I decide to rebuild my system.
  4. Download AutoPatcher and prepare a Windows/Office update CD/DVD.
  5. Create an image of the system just in case you missed/forgot something. There are a number of free imaging programs available. This way, even if there is something that you forgot to backup, you will still be able to get it back from the image.
  6. Perform a thorough check of your hard drive. If your drive has errors or problems (r you just want a bigger hard drive), now would be a really good time to replace the drive. Some tools include:
  7. Make sure that you have all of your account information for your Internet provider, including e-mail. Have their phone number handy in case you run into trouble.
  8. If you do not have all of your online accounts information memorized, now is a good time to write record them so that you do not destroy the information when you reformat your drive.
  9. Make sure that you have your wireless network information recorded and available.

If you have lost your passwords that are stored on your computer, here are some tools that may be able to help you out:

After You Reformat

Well, you’ve reformatted your disk so there is no turning back. Here is a general overview of the process:

  1. Make sure only the bare necessaries are plugged into the computer (monitor, keyboard, and mouse).
  2. Boot from the Windows CD and install Windows.
  3. Install all of the drivers that you backed up earlier.
  4. Plug in all of your peripherals and ensure that they are all working correctly.
  5. Install Office if you had it on your computer.
  6. Install all of the updates from your AutoPatcher CD/DVD.
  7. Run a disk clean and defragment on the drive.
  8. Reconnect your systems to the Internet.
  9. Install all of the applications that you want installed on the system.
  10. Migrate all of your files to your newly built system.
  11. Setup all of your accounts again.

I’m sure that there are a few things that I have forgotten but this is a really good start. Let me know what I’ve missed or if there is something that you do that I do not and I will add it to the list.

UPS devices have become so cheap these days that everyone should have one on all of their computers. What surprises me is that nobody has designed a standard computer power supply with built-in UPS capabilities.

Some of the advantages of such a design include:

  1. Continued running even when power goes out.
  2. Can (carefully) move a computer to a different room or location without shutting it down.
  3. Laptops do it, why not desktops?
  4. Only the critical devices (i.e. the computer) are on the UPS and not other non-essentials like monitors and printers. This will allow for a longer running system without power.
  5. The ability to gently shut down the system from a hardware (not OS) perspective.

If any of the readers out there are hardware developers and would like to pick up on this idea, feel free. Just drop me a line to let me know how the idea pans out!

It is only a matter of time before most IT professionals find themselves having to do some sort of a forensic analysis on a computer. The problem that most people come are then faced with is their lack of experience in performing these tasks.

And all of the pressure does not help either because there are often some pretty high staked involved.

This is where Helix comes in. Helix is a live CD that is designed to find out exactly what is on that computer and what individuals have done with it. From their website:

Helix is a customized distribution of the Knoppix Live Linux CD. Helix is more than just a bootable live CD. You can still boot into a customized Linux environment that includes customized linux kernels, excellent hardware detection and many applications dedicated to Incident Response and Forensics.

Helix has been modified very carefully to NOT touch the host computer in any way and it is forensically sound. Helix wil not auto mount swap space, or auto mount any attached devices. Helix also has a special Windows autorun side for Incident Response and Forensics.

Helix focuses on Incident Response & Forensics tools. It is meant to be used by individuals who have a sound understanding of Incident Response and Forensic techniques. That said Helix is used by the following organizations for Incident Response/Forensics Training:

  • Some of the tools that are on the Helix CD include:

    Many of you are familiar with the concept of computer imaging. Essentially, you take a system, configure it the way that you would like, and then duplicate the hard drive to all of the other systems, saving yourself all of the same steps that you did on the first system.

    Now, there are a lot of great commercial software programs out there that can do this for you. Acronis and Ghost come to mind. But, not everyone can afford these options. For those of you find yourself in this situation, I present you with a list of options that are available for free or are open source. (All descriptions are copied from their respective websites.)


    Partimage

    Partimage is a Linux utility which saves partitions having a supported filesystem to an image file. Most Linux and Windows filesystems are supported. The image file can be compressed with the gzip / bzip2 programs to save disk space, and they can be splitted into multiple files to be copied on CDs / DVDs, … Partitions can also be saved across the network since version 0.6.0 using the partimage network support, or using Samba / NFS. If you don’t want to install Partimage, you can download and burn SystemRescueCd. It’s a livecd that allows to use Partimage immediately even if your computer has no operating system installed (useful to restore an image), and it allows to save an image on a DVD on the fly.

    PING (Partimage Is Not Ghost)

    PING is a live Linux ISO, based on the excellent Linux From Scratch (LFS) documentation. It can be burnt on a CD and booted, or integrated into a PXE / RIS environment. Several tools have been added and written, so to make this ISO the perfect choice to backup and restore whole partitions, an easy way. It sounds like Symantec Ghost(tm), but has even better features, and is totally free.

    Clonezilla

    Clonezilla, based on DRBL, Partition Image, ntfsclone, and udpcast, allows you to do bare metal backup and recovery. Two types of Clonezilla are available, Clonezilla live and Clonezilla server edition. Clonezilla live is suitable for single machine backup and restore. While Clonezilla server edition is for massive deployment, it can clone many (40 plus!) computers simultaneously. Clonezilla saves and restores only used blocks in the harddisk. This increases the clone efficiency. At the NCHC’s Classroom C, Clonezilla server edition was used to clone 41 computers simultaneously. It took only about 10 minutes to clone a 5.6 GBytes system image to all 41 computers via multicasting!

    IRestorer

    Drive Snapshot (IRestorer) creates an exact drive image of your system into a file, including the operating system, installed programs, your data and all security attributes, while windows is running and you continue to work. If disaster strikes (a virus, worm, trojan, or hard disk crash), a complete and exact restoration of your system will be possible in only few minutes. The image file can be mounted as a virtual drive, so you can easily restore (or use) single files or directories, using the Windows Explorer, or other programs. Restart to DOS is only necessary, if you must restore your system partition. Otherwise there is no need to reboot, not even during installation. Drive Snapshot saves only the used disk space, compresses the data and is extremely fast, a P4 - 3.0 GHz will save approx. 2.5 GB/Min on a modern hard disk!

    Linbox Rescue Server

    The Linbox Rescue Server is an asset management software including 5 modules :

    • system backup for emergency crash recovery, hard disk cloning or deployment using a
      PXE network boot. This module was fully developped by Linbox FAS.
    • file backup, based on the famous BackupPC, to which we have added a configuration interface,
    • inventory, based on ocs-inventory agents, and on an agent which runs during the PXE network boot,
    • Software deployment module which works with Linux, MacOS X and MS Windows clients, or any Un*x system running OpenSSH,
    • remote control, based on TightVNC.

    HDClone

    Copies smaller drives onto larger ones for migrating or backing up complete installations as well as for data rescue. The download package contains a program to easily create a bootable floppy disk or CD/DVD under Windows with only few clicks. A floppy image, ISO image, and manual as PDF are also enclosed.

    DiscWizard

    If you are setting up your new drive, you can use the install instructions to assist in mounting the drive, then use the tools built into your operating system to prepare the drive.

    G4L

    G4L is a hard disk and partition imaging and cloning tool. The created images are optionally compressed and transferred to an FTP server instead of cloning locally.

    MaxBlast 5

    If you are setting up your new drive, you can use the install instructions to assist in mounting the drive, then use the tools built into your operating system to prepare the drive.

    DriveImage XML Backup Software

    DriveImage XML is an easy to use and reliable program for imaging and backing up partitions and logical drives.

    The program allows you to:

  • Backup logical drives and partitions to image files
  • Browse these images, view and extract files
  • Restore these images to the same or a different drive
  • Copy directly from drive to drive
  • Schedule automatic backups with your Task Scheduler
  • Image creation uses Microsoft’s Volume Shadow Services (VSS), allowing you to create safe “hot images” even from drives currently in use.Images are stored in XML files, allowing you to process them with 3rd party tools. Never again be stuck with a useless backup!

    Restore images to drives without having to reboot.

    DriveImage XML runs under Windows XP, Windows Server 2003 and Windows Vista only. The program will backup, image and restore drives formatted with FAT 12, 16, 32 and NTFS.

    DuBaron DiskImage

    DiskImage is the ultimate tool to backup and restore partitions, entire harddisks, usb keys, floppy drives and (read-only) optical media. DiskImage features built-in zip compression, it’s own compression method for data
    > 2Gb, MD5 and SHA1 checksumming, a hex editor, and various tools like drive speed and seek testing.

    Dumping and restoring partitions, usb sticks, floppies, optical media, diskimage is the swiss army knife.

    WinDD - Disk Dump for Windows

    WinDD - Disk Dump for Windows! Windows XP version of Unix ‘dd’ command. Safe, effort-free backup for FAT, FAT32, NTFS, ext2, ext3 partitions.

    Partition Saving

    Partition Saving is a DOS and Windows program that is used to save, restore and copy hard-drive, partitions, floppy disk and DOS or Windows devices.

    With this program you could save all data on a partition to a file (such as you could save this file on a CD for example). Then if something goes wrong, you can completely restore the partition from the backup file. You no longer have to reinstall every piece of software from scratch. All you have to do is restore the partition from the backup file and then update any software that was modified since the backup was created.

    NFGDump

    nfgdump (Ntfs-Fat-Generic-dump) is a Win32/Linux tool that dumps/restores NTFS (including 3.1=XP), COMPRESSED NTFS, FAT16, FAT32 and arbitrary (generic) partitions. Dump files support compression, encryption, splits, page file content removal, etc.

    Forensic Acquisition Utilities

    This is a collection of utilities and libraries intended for forensic or forensic-related investigative use in a modern Microsoft Windows environment. The components in this collection are intended to permit the investigator to sterilize media for forensic duplication, discover where logical volume information is located and to collect the evidence from a running computer system while at the same time ensuring data integrity (e.g. with a cryptographic checksums) and while minimizing distortive alterations to the subject system. The components of this package are not intended to preclude changes to the subject system while the evidence collection process is under way. A third party hardware or software write blocker should be employed in those circumstances where it is deemed necessary to guarantee that no changes occur to the subject volume prior to and after the imaging process.

    Self Image

    SelfImage is the little hard drive utility with big aspirations.SelfImage is capable of making an image file of a hard disk or hard disk partition, and can restore an image back to any drive or partition that doesn’t have open files. Useful for making backups. Unlike dd for Windows (or cygwin), SelfImage is capable of creating an image of a partition that is currently in use.

    SelfImage can even create images of partitions that Windows doesn’t recognize (partitions that Windows doesn’t have mounted on a drive letter). This is perfect for the dual-boot system, you can create an image backup of a Linux partition directly from Windows.

    PC inspector clone maxx

    PC INSPECTOR™ clone maxx is the new professional hard drive copying program from CONVAR. Using the new direct DMA support, data can be copied from hard drives in high speed mode with speeds up to 3.3 GB per minute.This high speed is achieved by PC INSPECTOR™ clone maxx through intelligent inspection of the PC motherboard and the hard drive controller. The software independently determines the fastest data transmission rate and achieves these exceptional speeds through optimal utilization of the DMA chipset on the motherboard of your PC.

    PC INSPECTOR™ clone maxx can be started directly from a boot diskette. The copying process is always based on the physical drive and is independent of the file system (e.g. FAT12, FAT16, FAT32, HPFS, NTFS, Ext2, Reiser, etc.) or the number of partitions.

    g4u - Harddisk Image Cloning for PCs

    g4u (”ghosting for unix”) is a NetBSD-based bootfloppy/CD-ROM that allows easy cloning of PC harddisks to deploy a common setup on a number of PCs using FTP. The floppy/CD offers two functions. The first is to upload the compressed image of a local harddisk to a FTP server, the other is to restore that image via FTP, uncompress it and write it back to disk. Network configuration is fetched via DHCP. As the harddisk is processed as an image, any filesystem and operating system can be deployed using g4u. Easy cloning of local disks as well as partitions is also supported.

    FOG :: A Ghost-like Computer Cloning Solution

    Fog is a Linux-based, free and open source computer imaging solution for Windows XP and Vista that ties together a few open-source tools with a php-based web interface. Fog doesn’t use any boot disks, or CDs; everything is done via TFTP and PXE. Also with fog many drivers are built into the kernel, so you don’t really need to worry about drivers (unless there isn’t a linux kernel module for it). Fog also supports putting an image that came from a computer with a 80GB partition onto a machine with a 40GB hard drive as long as the data is
    less than 40GB.

    Fog also includes a graphical Windows service that is used to change the hostname of the PC, restart the computer if a task is created for it, and auto import hosts into the FOG database. The service also installs printers, and does simple snap-ins.

    Each has its own pros and cons but all have a purpose. I am personally really liking FOG and am finding a lot of different places to put it to work.

    FarewellFriday was my last day of work before the big move. I have had to leave jobs a number of times in my IT career and I think this was probably one of my best exits so far. With the average person changing jobs several times over their careers, leaving one’s job with class is an extremely important skill to master.

    While this may not be a very technical post, I think that it is something that is critical for every IT person to know. So, with that in mind, here is what I have learned about leaving gracefully.

    Don’t Burn Your Bridges

    In my mind, this goes without saying but for some it may not be as obvious. You never know when you will need these people or this company again. You might be looking for work in the future and need a reference or maybe they will be hiring again in a few years and you might be needing a job.

    It never hurts to have more people on your side than against and pushing people away is never a good thing.

    Give As Much Advance Notice as Possible

    When my wife and I first decided that we were going to move, we know that this was going to happen more than two years in advance. I notified my employer immediately and they have known for a very long time that I was moving on. While I understand that this is a very unusual situation, it is generally in everyone’s best interest for you to give as much advance notice as possible.

    My general rule of thumb is to give my employer twice as long notice as is legally required of me. I generally give at least one month.

    Also, the more specialized your position and the harder it is to find a replacement, the longer your notice should be. This benefits your old employer and also indicates to your new employer that you are loyal and trustworthy.

    Help to Find Your Replacement

    Only you really know what you do and that makes you a very important asset when recruiting for a replacement. Help your old employer find your replacement by offering to help with the interviews, talking with friends whom you know in your industry that may be interested in your position and help them word the Internet and newspaper “Help Wanted” ad.

    Train Your Replacement

    Once your replacement has been found, help to train them. Get them to work a few days with you so that they can learn the ropes from a veteran. While your company can provide them with a job description and basic training, only you can show them those special nuances of the job that you have learned from your years of experience.

    Work As If It Is Your First Day Until Your Last

    A lot of people start to slack off as their last day draws near. This can be a huge mistake. This became very clear to me as I was leaving my last position. I did a lot of extra tasks that I was not technically required to do but it was noticed and because I pushed hard right to the very end, they decided to give me the annual bonus even though I was not technically eligible for it because I was leaving before the bonuses were distributed. Sounds like a win-win to me!

    Maintain a Positive Attitude

    It is really tempting to have a “What are they gonna do? Fire me?!” attitude once you have handed in your resignation. Don’t fall into this trap. These are the types of things that people remember when prospect employers call for references. You also don’t want people’s final thought of you to be “What a jerk!” or worse.

    Ask For Letters of Reference

    Letters of reference can be very helpful when looking for future work, even if you already have a new job lined up. Now is the time to ask for them because you are in a better position to positively influence what is in the letter. It is much harder to get an accurate and glowing letter of reference several years down th road.

    Offer to Help in an Emergency

    This hold especially true if you are in a technical position. I told my old employer that if there was an emergency, I would do what I could to help out my replacement and the rest of the technical crew. I made it very clear that this would be on a best effort basis and that their would be some compensation required for my help but that I would be there if needed.  This increases people’s opinion of you while also protecting yourself from being taken advantage of.

    Make a Clean Break

    I remember very clearly one individual that I worked with who quit to work for another company. His decided to take some time off before starting his new position.  Imagine how surprised we were when he showed up at the office the day after his last day of work!  He hung out at in the break room.  He would wait for people at the coffee shop during coffee break.  Eventually, his old manager had to come right out and tell him that he didn’t work there anymore and could no longer come around to “visit”.

    Once you have quit your job, move on and do not dwell on the “good ol’ days”.

    Keep In Touch With Your Work Friends

    This may seem contrary to the previous point but actually, it is complimentary to it.  A friend that I met at a previous job has become a real mentor and support to me, even though he and I have not worked together a coworkers in over six years.  We made it a weekly ritual to get together for lunch and shoot the breeze.  But, we made sure to meet at a restaurant that was not one frequented by other former employees.  This way there was a very clear break between me and the company but not between me and my friends.

    Write a “Thank You” Letter to Your Boss

    Your parents taught you from a young age to always say thank you.  This also goes for the people who were responsible for putting food on your table and shelter over your head in exchange for work over the past number of months or years.  Do the classy thing and put a thank you in writing emphasizing everything you learned from working for them and for the opportunities that you received from the position.

    Send a Farewell E-mail

    Depending on your company, this can be a broadcast e-mail to everyone in your company, your office, your department, or just a few select friends.  Make sure you thank everyone for their contributions and let them know what the future holds for you.  You may even want to provide them with updated contact information.

    Don’t Brag About Your New Job

    I remember once a person working on the same team as me got a new job and from the time he announced he was leaving to the actual moment he walked out the door for the last time, all he could talk about was how wonderful his new job was, how much more money he was going to be making, and how wonderful the new company’s corporate culture was. All he ended up doing was making those up us left with our crappy, low-paying jobs and depressing corporate culture feel depressed.

    While you want people to feel happy about your new career, you want them to be happy that you are moving on to bigger and better things, not that you are just moving on.  Don’t lift yourself up by putting others down.

    Conclusion

    I know that some of these are not going to be possible in every situation, especially if you are leaving under less than desirable circumstances (i.e. fired, laid off, etc.) but do whatever you can to implement as many of these as possible to maintain your professional status.
