Exchange Recovery - Now in the Simplest and Most Effective Manner
In the present scenario, fast, efficient and rich access to emails, notes, contacts, calendar entries, journal, attachments and other personal data have become prerequisite for the success of businesses. In the current scenario, Microsoft Exchange Server is becoming more and more popular day by day. The growing popularity of the this Server can be attributed to the fact that it delivers a messaging system, which addresses all of the business needs such as security, speed and availability, and so on. Moreover, the Server creates a separate mailbox for every user, which can be accessed through Microsoft Outlook. However, the Exchange Server database may get damaged in some cases and does not allows you to access the data, send or receive emails, create backup and perform any other operation on the database. This creates a situation of heavy data loss and requires Exchange Server Recovery at the earliest.
Consider a situation, when you are trying to access your mailbox from the Exchange Server. You are not able to access your mailbox, the operation does not completes and you may find the following Event ID in Application Event Log of the Exchange Server:

Category: Database Corruption
Type: Error
Event ID: 447
User: N/A
Computer: VOYAGER
Description: Information
Store (2624) A bad page link (error -338) has been detected in a B-Tree (Object Id: 2283, Pgno Root: 213598) of database
E:\Exchsrvr\MDBDATA\priv1.edb (3253654 => 3304833, 3253654).
In the above-mentioned situation, you are unable to send any file as an attachment along with the email. Using Microsoft Outlook, you can send plain text emails but you cannot access anything from the Exchange Server database and cannot send any file as an attachment along with the email. In case you try to attach any file to your email, the Microsoft Outlook gives the below-mentioned error message:
"The operation failed."
The above-mentioned error occurs due to damage to the EDB (Exchange Server Database) file or lets say the above-mentioned error appears when your EDB file becomes corrupt.
As said earlier, this problem occurs due to the EDB (Exchange Server Database) corruption. A number of factors are responsible for EDB corruption. Some of them are as follows:
1.Virus infection
2.Missing file objects
3.System crash
4.Improper system shutdown
5.Application malfunction
To deal with this, you need to perform Exchange Server Recovery. This simply means that you need to repair your EDB file and restore all your valuable and mission critical data from it. You can easily and successfully recover your Exchange Server Database file from a recent, valid and complete EDB backup.
In case of unavailability of a valid EDB file backup, you can repair your EDB file and restore your valuable data using an efficient, powerful and advanced third party Exchange Recovery tool.
These third party Exchange Recovery tools use quick, powerful and efficient scanning algorithms to methodically scan the damaged or corrupt EDB file and restore all of the Exchange Server mailboxes and their objects.

Data Recovery
A computer hard disk crashing is the stuff nightmares are made of for all those who depend entirely on computers for their day-to-day work. When one talks of a hard disk crashing, it generally implies problems in the computer, the magnitude of which can be ascertained only when the data is recovered.
There are two basic types of damage to the hard disk, physical damage and logical damage. As the name would suggest, physical damage implies actual damage to parts of the computer or the central processing unit. It would comprise of wires, circuitry, chips, fuses, burnouts, etc. It means replacement or repair of parts. Logical damage, on the other hand indicates damage to the file system like incorrect reporting of various functions, system crashes, loss of data, directories gone wrong and other unaccountable discrepancies. Most operating systems come with a basic inbuilt tool kit and are able to repair faults up to a certain level.

Backup is very important and even a basic user should regularly implement it. Backup has to be done regularly, checked regularly and the data has to be uncompressed. Data backup has different roles to play. An effective rotation scheme, backup to a remote location and recovery strategy involves use of checksums to avoid making redundant copies. Data can now be salvaged from the backup storage files. There is another feature that ensures effective storage and that is continuous backup where backup is an ongoing process. It is far more effective than traditional backup systems.
Most manufacturers ensure that their product has certain features regarding data recovery and repair of logical systems. Call in a professional and you will be able to retrieve most, if not, all your lost data.

ISO to Backup and Restore Your Hard Drive
Do you ever calculate the times you have performed operating systems installations? Well, personally, I cannot remember the actual times I have installed Windows for both work and personal. Let me give some rough figures.
Windows 3.11 - 5 times
Data Backup
Windows 95 - 5 times
Windows 98 - 50 times
Windows Me - 5 times
Windows 2000 - 5 times
Linux Red Hat - 3 times
Windows XP Pro - 100 times
Windows Server 2003 - 3 times
Windows Vista - 8 times
Honestly, I never enjoy going through the process of installing any of the operating systems. For those who know me, I will most probably be looking at the progress bar during the installation as if I am very interested. However, I am actually very frustrated and hoping that the progress bar could go as fast as it could be.
Attended Installation
Well, some of you may know that the normal installation through the OS CD or DVD (such as looking at the progress bar and clicking several next buttons) is called attended installation and it is possible that you create your own unattended installation using deployment tools. However, I will not be covering the Windows unattended installation.
Unattended Installation
Most companies use Imaging (ISO) to create a duplicate copy of installed operating system so that they can easily install the exact copy of operating system with their corporate settings to every new machine by extracting the ISO.
ISO Images
- ISO is an archive or a duplicate or backup copy of whatever files that you wish to store
In other words, I create ISO images to backup my entire operating system hard drive data.
Hiren BooCD and Norton Ghost to create ISOs
I use Hiren BootCD, the all in one Dos Bootable CD. One of the software included is Norton Ghost, which can be used to create hard disk images known as ISOs.
ImgBurn
ImgBurn is a Windows program and it's free. You can install it and create ISO images or burn the images into CDs and DVDs.
ImgBurn VS Hiren BootCD
The difference between the two is that ImgBurn needs to be installed as a Windows program and undeniably, a good and easy tool to create ISO images. However, if your hard disk is corrupted, you won't be able to use ImgBurn unless you have dual booting. Thus, you need to use HirenBootCD and Norton Ghost to extract your ISO images to the corrupted hard disk.
The Idea
Simple:
1. Complete an attended installation or manual installation from CD or DVD on one machine
2. Install all the necessary programs that you need such as Microsoft Office, Adobe Acrobat Reader and the likes
3. Perform operating system updates
After performing the steps above, boot your computer from Hiren BootCD and you will come to a screen for you to select the types of software that are bundled. Choose Norton Ghost from the list and from there, you can create an image out of your partition drive.
The ISO file can be stored in your hard disk for easy access but not in the same drive where you install your operating system. If your computer fails to load or startup properly, you can then pop in Hiren BootCD, boot from the CD and restore the ISO file.
The Practice
My own practice is to have at least two partitions, namely C and D.
- C drive will be the drive where I install my operating system and programs
- D drive will be my document drive
- A copy of ISO created from the C drive will be kept in D drive
Benefit
When operating system is corrupted, none of my document files will be affected when I extract ISO into the C drive. Extracting ISO to C drive will overwrite every data in C drive without any warning. However, after extracting the ISO, you will get the same settings and operating system as of the time when you create the ISO.
What's more? You do not have to go through the process of keying the product key, selecting the time zone, installing the drivers and commonly used programs.

Disaster Recovery - 5 Practices to Protect Your Business From Disaster
Almost everyone who has experienced data loss has had the same thought, "I know it happens, but it won't happen to me." Here are 5 ways to prevent your business from the unlikely disaster that could ruin your company.
1. Keep inventory. Be sure to keep photographs along with the receipts for all items of value that could potentially be destroyed so that you are appropriately compensated (if you have insurance) instead of being out of luck.
Data Backup
2. Keep copies of vital data. Whether your data is co-located or simply stored on hard drives, be sure to have backup copies of data that is essential to continue your business. Be sure to keep this stored at an offsite location as some events such as natural disasters may wipe out everything in the general area.
3. Go paperless. If you have loads of folders containing client files or critical company information, storing these away in seemingly safe file cabinets is extremely risky. The files could be ruined by any number of natural disasters as well as by human error. When a file is on paper it is time consuming to make physical copies and costly to find additional protected space to store the copies so it is safest to store these electronically.
4. Redundancy. Duplicate all important components of your system to make it fail-safe. If done correctly this forces the component as well as its duplicate to fail simultaneously in order to cause a system failure. This may be difficult to perform with little electrical experience but a professional can be hired for a very reasonable price.
5. Store expensive equipment or documents on the top floor. Unless tornadoes are your only fear, keeping things out of the basement and higher up will save you the outrageous expenses associated with flooding.

How to Rescue Data From Your Damaged Hard Drive
A damaged hard disk drive is one of the most unpleasant types of hardware failure. No, I don't mean that a burned processor or a damaged memory block are more enjoyable. Not at all - they are also disasters and in terms of money generally it is more expensive to replace a processor than to replace a hard drive but damaged hard drives have one very irritating property - you lose not only your hardware but also all or some of your data. Data is priceless and if you don't have a backup copy of it, then you are lost.
However, not all hard drive damages are that bad. There are cases when the hard drive is damaged but the data on it is alive. So, if your hard drive crashes, don't panic but hope for the best - i.e. the drive might have become an obsolete piece of machinery but at least your data is not buried inside. There are different strategies for evacuating data from a damaged hard drive and which one you can use depends on the sort of damage, as we'll see next.
Data Backup
What Is a Damaged Hard Drive A damaged hard drive come come in many flavors. In addition to that, there are many cases when the drive is not damaged but due to some reason the data can't be accessed. For a non-specialist all these cases might look the same - I can't access my files, so my hard drive must have gone off, while in reality the hard drive is perfectly OK but your data is inaccessible because of some prosaic reason.
Without getting into technical details, the shortest (and hardly most precise) explanation of a completely damaged hard drive is that this hard drive can't be accessed with any means even by a qualified PC technician. So, unless you are a PC technician yourself, you can't determine on your own if the hard drive is totally dead or not. However, since there are many cases when a drive is still alive but it can't be accessed due to a variety of reasons (most frequently software issues) you can try some of the approaches in the next section and see if they work. Even if they don't work, they will do no harm, but this does not mean you shouldn't be cautious when applying them.
What You Can Do on Your Own One of the cases when the hard drive is not physically damaged but is unaccessible due to software reasons is when the partition on which the data resides is inaccessible, or at least not from your operating system. In this case you can use an alternative operating system, for instance a Live CD with a Linux distribution and see if you will have more luck accessing the partition. This will work, if the partition table on your computer is not totally messed up. If you see that the data is still unaccessible, don't attempt to mess up with the partition table because you can make things worse. Instead, hurry up and find a PC technician and pray that he or she will be able to recover your data for you.
Another case when the data might still be alive is when the drive has been formatted on a high level. If the drive has been formatted on a low level, the extraction techniques will not work because the data has been physically destroyed. There are many tools to unformat a formatted drive. Most of the tools are paid ones but you can find free as well. Hiren's Boot CD comes with a bundle of data recovery tools and I generally prefer to use them than any other tools.
Software problems are common but hardware problems - I.e. bad sectors or a damaged controller are also not an exception. Unfortunately, there isn't much you can do about them. If data is sucked by a bad sector, then in 99% of the cases it is gone for good. The 1% stands for the rare chance that you have made copies of exactly this file and the copy is not on a bad sector but this is really a lucky exception. You can take the hard drive to a service but it is unlikely that they will be able to do much.
Another technique you can try on your own without risk to make the damage more severe is to go to your HDD manufacturer's site and see if they provide retrieval tools. Usually hard drive manufacturers provide diagnostic tools but if you are lucky, chances are that you will find a data retrieval tool as well. Very often the diagnostic tools themselves not only check for problems but they also can fix some issues, so they could help you save your data as well.
The above mentioned techniques to extract data from a damaged hard drive are only a small fraction of what can be done. However, many of the other techniques are more complicated and they do require some knowledge about a hard drive's architecture, so I wouldn't recommend you to apply them because you can make a lot of damage. Some of the techniques that require opening the computer case or messing with the parts of the disk itself are too dangerous to try at home. No, you will hardly destroy your home but you can surely further damage the hard drive, making it impossible even for a technician to help you. Additionally, you can void the warranty for the computer system, which is hardly what you want to achieve.
Take the Hard Drive to a PC Technician If you have tried to rescue the data from your hard drive on your own to no avail, you have no choice but to take it to a service. A PC service has more equipment than the standard user and there is a chance they will be able to help you but still, don't expect miracles. In some cases data extraction services could be free of charge, especially if you have bought the hard drive from them and the warranty has not expired yet but in other cases you will have to pay.
As you probably guess, fees vary. As a rule, the cost depends on the volume of data that needs to be extracted but generally it does not cost a fortune - you might be able find somebody to do it for around 0. Still, if your drive has serious physical damages, even if you go to a more expensive data rescue lab, there is no guarantee that your data can and will be restored.
Skilled PC technicians have more tools and techniques and their disposal. If you are interested in contacting a reputable company, try the service listed below. If you would like to learn more about hard drive data recovery techniques, here is a good article: www.wikihow.com/Recover-a-Dead-Hard-Disk. Some of the information in these articles might be useful to diagnose the problem, but don't even think of applying the techniques on your own. It is really risky!
