Right now you probably in a lot of mental pain, and all you’re concerned about is recovering your data as quickly as possible - so we’ll refrain from comments on the wisdom of regular back ups. The time for preventative measures has gone - the issue at hand is data recovery.
First - a simple tip could save you a lot of money. Take out your rolodex and get hold of your tech-savvy friends. If you’re in luck, they’ll offer to help, and if you’re really lucky, they might even have some disk recovery software.
If you’re out of luck, then get out your wallet or purse out now... because this is going to cost you. Also, be prepared for a lot of time being wasted - data recovery can take a long time.
The first thing to establish is what exactly is wrong with your hard disk:
* Either your computer won’t boot up, or
* Your computer boots up OK but you can’t see one of your other drives.
Let’s see if we can eliminate the worst scenario. Listen closely to your hard drive - is it making any sort of weird noise, such as scratching, scraping, ticking etc?
If so, then your drive is physically damaged and the only hope that you have is to take it to a data recovery service where experts might be able to get your data off for you. These services are expensive and time consuming - so you need to make a judgement call as to the value of data on the disk:
If it’s only your saved game data or downloaded music files you would like back, you’re probably better off kicking yourself for not backing up, and accepting the data loss.
If, on the other hand, it’s a book or other type of information product that you’ve been working on for years, then send it to a data recovery service for an evaluation and quote - it usually costs nothing.
If your hard disk sounds OK, then you stand a decent chance of recovering data yourself.
First you’ll need to download some software to help you out.
Unfortunately, the better software utilities are not free, but the good news is that many allow you to try them out to see if they can access the data. There are some freeware products available but generally speaking these are not easy to use - no user interface / little documentation, or they are not very effective.
There’s a list of recommended software on our site - http://www.recoverdatafiles.com - compare the different options then download a few of the trial versions.
Your next steps will be based on how your hard drive/s were setup:
* If you only have a single hard drive that has not been partitioned or split into different “logical” drives, you’ll probably need to attach the hard drive to another computer that has enough space to store all your data. This can be quite technical so if you don’t have the skills please get a computer savvy friend to help out.
Another option is to purchase an external USB hard drive case. You can then simply slot the hard drive into the case and plug it into another PC using a USB port.
* If you have a multiple drive setup and your computer boots up fine, then it will merely be a case of getting the downloaded software to read the files and then copy them to another drive - provided you have a drive with enough space on it. If not, you’ll need to attach the hard drive to another machine with enough spare capacity.
* The scenario where you have a multiple drive setup, where the problem drive is the one that contains your operating system files is more tricky.
Look for a data recovery software package that has a boot disk option available. What this means is that when you start your computer with the boot disk in it, it will automatically run the data recovery program without trying to start windows. You should be able to see your files and then copy them across to another drive.
Hopefully these tips will enable you to get all your important files back.
Once you’ve had some time to recover, please take a look at the various articles on our website - our goal is to make it one of the best resources on data recovery.

Data Backup - Prevention Is Better Than Cure
by: Justin Koh
Imagine that you have been working on a file for the entire day and there was a power surge that caused your computer to 'black out'. It would have been a frustrating experience for us as we had put in a lot of time and effort into it. I am sure that many of us would have experienced data loss in some form or another and have learnt to be wiser to backup our data to avoid any form of data loss.
Have you ever thought of a worst case scenario where a fire broke up and destroy your computer or where your laptop got stolen? Should that happen, the first thing that comes into your mind is the thousands of dollars that you spend on your computer or laptop and you would feel very upset about it. However, when you thought for a second moment, you started to realize that what is really valuable are the amount of data that you have built up over the years in it. Though hardware can always be replaced, even at no cost to you if you have insurance, but lost data is gone forever.
Lost data such as the thousands of mp3 and movies that you have downloaded from the Internet, thousands of digital photographs that are impossible to replace are lost in an instant. This form of data loss hits home especially hard when the laptop holds the lifeblood to your business. Imagine all your business contacts documents and contracts that you have painfully built up over the years would be vanished just like that. Your business would be wipe out overnight.
Do not wait for the worst to happen before you start to consider about data backup.

Understanding XML Server
by: Balaji B
XML Server can be a Web Server that stores the XML files in it and serves them on demand. The XML Server would have processing capabilities with an XML engine and to transform the XML document to other forms. Basically a server which hosts and serves the XML documents is called a XML Server.
There are many commercially available XML Servers in the market. The popular among them are the Tamino Server, the Sonic Server and the FDX XML Server. Though the basic functions of these servers are same the way they are implemented and the features that they support varies.
The Tamino XML Server is from Software AG and is used to publish and exchange all kinds of data especially the XML documents in the native format. It handles open standards. Leveraging on the XML technologies will improve an organizations data access.
Exchange of data between different applications on different platforms is possible using XML technologies. Hence organizations are moving on to store their data in XML format to take advantage of the XML technologies. Storing the data in XML format improves the performance of delivery and scalability of your applications with low operational and administrative costs.
In traditional relational databases, data is stored in rows and columns which can be too complex. But in the case of an XML Server such complexity is avoided and any data can be stored which includes even multimedia files and even relational data. These data can be easily retrieved at lightning speed using a Tamino XML Server.
To retrieve data that is requested by any application, XQuery is used in Tamino XML Server. This server implements the XQuery specification draft. Hence queries on the server can be issued using the internet and data can be returned in any format by using XSL style sheets. Thus the customers can manipulate the format of presentation of the data that is presented using style sheets. High speed retrieval of data is possible in XML Server.
The Tamino XML Server is robust, reliable, and scalable. It is used in mission critical environments and there is almost no failure and loss of data. It is reliable in the sense it supports backup of data that can be stored in external devices or remote devices and used in clustered environments. The number of users can be increased and the load on the server can also be increased.
The document structure can take additional elements without changing the entire structure of the data store. These characteristics of the XML Server help it to be used in mission critical environments. Developers can develop XML applications very faster by using Tamino XML Server. It can be easily integrated with application servers.
FDX XML Server is another XML Server available in the market. This product is created by Snapbridge. This server is also used to create and deploy sophisticated XML applications. XSL, XSLT and scripts are supported in this server so that data can be transformed to any format requested by the user or any other application.
Sonic XML Server is another product from Sonic software which is built upon the native XML processing engine. This helps in pipelined processing of XML documents which eliminates the need for generating intermediate xml text file for processing. This improves the speed of the transaction dramatically.
This pipelined processing of the document helps in very large and complex processing tasks to improve the speed of those tasks. The in-built engine in the Sonic XML Server enables a user to store any size of XML document in it and to query, retrieve and update that data.
We have seen that an XML Server is any server that gives an XML document as an output so that the other applications can use it for processing. The document can be delivered in any format using XSL and XSLT engines. It is possible for us to write some code in ASP which will serve an XML document to the user when they view that ASP page. We can store this code in a web server and this code can be said to be a very simple XML Server since it serves the user with an XML document.

The Function of Recruiting Database Software
by: Kent Pinkerton
Businesses must be fully staffed in order to live up to their potential. All job openings must be filled as quickly as possible with the best candidate for the job. With all of the quick decisions needed when hiring, it is important that recruiters are able to instantly access any information that they need about applicants. Recruiting database software organizes applicant information in such a way that any information on the applicants is just a few keystrokes away.
Recruiting database software can store and organize all of an applicant’s information in several different ways. These programs add applicants’ resumes to a database where they are stored for future viewing. Recruiters are able to access the entire database at any time. They can look at an applicant’s entire resume, or they can look at particular parts of the resume, like the contact information or previous job experience.
The resumes are stored in such a way that recruiters can filter out the particular information that they need. For example, if a recruiter wants to look at all applicants who have a master’s degree, the recruiting database software can show them a list of applicants whose resumes mention having a master’s degree. Or if the recruiter needs to fill a position extremely quickly, they can search for applicants who live nearby and would not need to relocate. Recruiting database software can filter out unqualified applicants. If applicants do not have particular qualifications such as relevant work experience or a college degree the software can mark these resumes so that the recruiter is aware of what these applicants lack. Recruiting database software programs are a great addition to any company that hires new employees. Firms that do their own recruiting benefit from the streamlined organization that this software provides. Professional recruitment and staffing companies can save a significant amount of time and money by utilizing recruiting database software.

The Value Of An Oracle Database
by: Sandy Baker
There are some very large, very powerful companies out there that have saved quite a bit of money using an Oracle database. Will your company be one of those? Or, will you simply overlook this opportunity? In order to know if in fact an Oracle database will help you, perhaps you have to know a little more about it. Also, you need to realize the differences that are out there in various versions of the Oracle database. Gathering this information will help you make a sound decision about the use of this product in your business.
First, realize that the Oracle database is available to be used and can be benefited from by virtually any size of business. Large corporations, medium sized companies, and even small organizations can all benefit here. What makes it nice to everyone as well is the lower prices that are currently being offered on Oracle database systems. There is no doubt that the introductory price is something to turn heads.
The system we will mention here is the Oracle Database 10g Products. These are, believe it or not, the first databases designed for grid computing in the industry. Your options are many:
• Enterprise Edition: Packed full with the highest level of performance and scalability. You will find reliability in OLTP as well as in decision support, and management activities.
• Standard Edition: Clustering support is provided with this 4 processor version.
• Standard Edition One: Same great stuff with a 2 processor version that is perfect for the entry level.
• Personal Edition: Perfect for an individual
• Lite Edition: Great option for managing mobile database applications.
While the features of each of these Oracle database options are many, it makes sense for each and every business out there to find out how well these products can serve their basic needs. Take a moment to see what they can do for you and you may just be impressed with the options that are available to you in Oracle database.

Music CD-R vs. Data CD-R: Is There A Difference?
by: Mike Waters
You wouldn’t believe how many times I run across this question. Is there a difference between music CD-Rs and traditional data CD-Rs? I think what people really want to know is if I buy a data CDR can I still put audio on it and vice versa. Well, hopefully this article will shed some light on the confusion and give you some insight into which type of blank media best suits your needs.
The simple answer to this question is yes. There are differences between music and data CD-Rs. However there is a big neon green flashing asterisk next to the yes that indicates to the informed consumer, that no there is not a difference. Let me explain.
Depending on where you gather your information, there are some articles that indicate minor differences between data and music CD-Rs. For starters, there is the name difference, but that’s obvious. There have also been rumors that the recording industry receives a very small percentage of each sale of blank music CD-Rs. However, that rumor has yet to be verified to my knowledge.
What is known is that there are technical differences in what is embedded in blank music CDs in comparison to blank data CDs. These embedded differences center upon bytes within the sub channels of the actual blank music disc. But does that really make a difference in quality or what types of information can be stored on the disk?
Not really. Both audio and data can be duplicated onto both music and data CD-Rs. I’ll say it again. Audio and data can be burned onto music and data CD-Rs. However, whether or not you can get data onto a music CD-R depends on what type of hardware is used to burn the blank CD.
If you are using a PC to do all of your burning, then it doesn’t matter. PCs do not differentiate between music CD-Rs and data CD-Rs. They simply see a blank media and duplicate information on to it pertaining to the settings you have outlined in the software you are using to burn the CD.
However, if you are using a separate home CD burner, it may or may not allow you to burn data/music onto a generic blank data/music CDR. Proprietors are funny like that. They really only want you to use blank media with brand names that they have approved of.
So my advice is if you are doing most of your CD duplication on the computer, it doesn’t matter which type of blank CDR you use. They both will work fine in most cases for storing audio and data. However, if you are using a CD writer outside of your computer for you burning needs, check the manual and see what they recommend.

ADSL (Asymmetric Digital Subscriber Line) - Description
by: Jeremy Maddock
ADSL is a type of broadband technology that allows for digital data to be sent at high speeds along already-existing copper telephone lines, while allowing for the transmission of analog (voice) data at the same time. ADSL is Asymmetric in that it uses most of the channel the channel to transmit "downstream" data to the user, and a much smaller part to receive "upstream" data sent by the user. Although there are wide ranges of ADSL configurations available, the most common type of connection offers maximum transmission speeds of approximately 1.5 Mbps upstream, and 128 Kbps upstream. This is considerably faster than an ordinary dialup internet connection.
