Data loss is an expensive reality. It's a hard fact that it happens more often then users like to admit. A recent study by the accounting firm McGladrey and Pullen estimates that one out of every 500 data centers will experience a severe computer disaster this year. As a result, almost half of those companies will go out of business. At the very least, a data loss disaster can mean lost income and missed business opportunities.
The other side of data loss is the psychological and emotional turmoil it can cause to IT managers and business owners. Despair, panic, and the knowledge that the whole organization might be at risk are involved. In a sense, that's only fair, since human error is one of the two largest contributing factors in data loss. Together with mechanical failure, it accounts for almost 75 per cent of all incidents. (Software corruption, computer viruses and physical disasters such as fire and water damage make up the rest.)
Disk drives today are typically reliable. Human beings, it turns out, are not. A Strategic Research Corp. study done in 2000 found that approximately 15 per cent of all unplanned downtime occurred due to human error. A significant proportion of that happened because users failed to implement adequate backup procedures, either having trouble with their backups, or having no backup at all.
How does it happen that skilled, high-level users put their systems - and their businesses - at such risk?
In many cases, the problem starts long before the precipitating system error is made, that is, when users place their faith in out-of-box solutions that may not, in fact, fit their organization's needs. Instead of assessing their business and technology requirements, then going to an appropriate engineered solution, even experienced IT professionals at large corporations will often simply buy what they're sold. In this case, faith in technology can be an vice instead of a virtue.
But human intervention itself can sometimes be the straw that breaks the technology's back. When the office of a Venezuelan civil engineering firm was devastated by floods, its owners sent 17 soaked, mud-coated disks from three RAID arrays to us in plastic bags. A tough enough salvage job was made even more complex by the fact that someone had frozen the drives before shipping them. As the disks thawed, yet more damage was done. (After eight weeks of painstaking directory-by-directory recovery, all the data from the remaining fifteen disks was retrieved.)
Sometimes, the underlying cause of a data loss event is simply shoddy housekeeping. The more arduous the required backup routine, the less likely it will be done on a regular basis. A state ambulance monitoring system suffered a serious disk failure, only to discover that its automated backup hadn't run for fourteen months. A tape had jammed in the drive, but no-one had noticed.
When disaster strikes, the normal human reaction is panic. Because the loss of data signifies critical consequences, even the most competent IT staff can jump to conclusions, and take inappropriate action. A blank screen at a critical time can lead to a series of naive decisions, each one compounding the preceding error. Wrong buttons get pushed, and the disaster only gets worse. Sometimes the pressure to correct the system failure speedily can result in an attempt to reconfigure an entire RAID array. IT specialists are typically not equipped to deal with crisis modes or data recovery techniques. Just as a good physician is trained to prolong life, the skilled IT specialist is trained to keep the system running. When a patient dies, the physician turns to others, such as nurses or counselors to manage the situation. When significant data loss occurs, the IT specialist turns to the data recovery professional.
Data recovery specialists are innovative problem solvers. Often, the application of basic common sense, when no-one else is in any condition to apply it, is the beginning of the journey towards data recovery. The data recovery specialist draws on a wealth of experience, married to a "never say die" attitude, and a comprehensive tool kit of problem-solving procedures. Successful recovery outcomes hinge on a combination of innovative logistics, applied problem-solving, and "technology triage," the process of stabilizing an affected system quickly, analyzing and treating its wounds, and preparing it for surgery. The triage process sets priorities, such as targeting which files are needed first or which are absolutely vital to the functioning of the business, and establishes whether files might be recovered in less structured formats (such as text-only), which may be desirable when time is crucial.
The art and science of professional data recovery can spell the difference between a business' success or its failure. Before that level of intervention is required, though, users can take steps to ensure that the probability of a data loss disaster is minimized.
Basic to any business technology plan is a regular fire-drill procedure. Back-up routines may be in place, staff may assigned to specific roles, hardware and software may be configured - but, if the user isn't completely sure that everything works the way it should, a data loss event is inevitable. Having adequate, tested, and current backups in place is critical. A hardware breakdown should not be compounded by human error - if the malfunctioning drive is critical, the task of dealing with it should go to a data recovery professional.
Just as data loss disasters are rooted in a combination of mechanical failure and human error, so, too, the data recovery solution lies in a creative marriage of the technological and the human. The underlying philosophy of successful data recovery is that technology is something to be used by human beings, not something that uses us.

Thumb Drives - Great New Technology
The ability to easily move data from PC to PC with minimal inconvenience is just another benefit computers have brought to the current business world.
Over the past few years, the different options to save and move data have multiplied dramatically. Usually the floppy disk (with it's 1.2 MB limitation), ZIP drives, CD-R's & CD-RW's, and even tape backups are the common ways to move data on non-networked PC's.
The latest innovation, the USB Removable Flash Memory (Thumb Drive, Key Drive, Flash Drive, USB Drive, Micro Drive) brings a whole new meaning to easy transport of data. These USB compliant devices are small enough to fit on a key ring or carry in your shirt pocket.
As a way to protect sensitive information, the security of one of these drives can't be beat. It's in your pocket!
Their size belies a huge data storage volume; the current sizes start at 16MB and go up to 4GB. The pricing on these devices is steadily falling, making the purchase of one of these handy drives almost a must have item.
Check out the accessories at your local computer store or go online to get the best deal.
For very little cost you can now conveniently move data between PC's just as easily as accessing the data on your internal hard drive.

More Details on AMD's Opteron
More Details About the Opteron emerge at this year's MicroProcessor Forum
As more details emerge regarding Opteron at this year's MPF, we thought it would be a idea to discuss the Opteron SPEC and bandwidth numbers disclosed by AMD at the MPF. Fred Weber's presentation, shows that the current 2 GHz Opteron samples with 1 MB L2-cache and dual-channel registered PC2700 DDR memory are to reach aSPECint2000 score of 1202, and a SPECfp2000 score of 1170.

These scores were obtained using Intel 5.01 compiler, in 32 bit mode. According to Fred Weber, a "real 64 bit" compiler should boost the Opteron's performance with by 20% (thanks to 8 additional registers in 64bit mode). However, the compiler will, of course, have to be as good as the current Intel one in terms of optimization to be able to realize that level of improvement. Below is a chart of current SPEC CPU2000 results with the Opteron estimates included. It is not known whether or not these estimates are for Base or Peak performance, but we will assume they are peak to be conservative.
As you can see, the 2 GHz Opteron - if it were to be released today - would by far be the fastest processor in integer intensive tasks. The improved branch predictor and lower latency of the memory subsystem are probably the reasons why the 2 GHz Opteron is no less than 29% faster than a 2.25 GHz Athlon. We speculate that the 5.3 GB/s bandwidth is the main reason why the 2 GHz K7 FPU is now able to beat the Pentium 4 at 2.8 GHz, something it couldn't do in the Athlon XP.
The industry does not sit still, of course. The Opteron is currently scheduled to be introduced during the first half of next year (roadmap) -- probably in Q2, with the desktop version expected to follow in the third-quarter. This is something that needs to be factored in when looking at these performance estimates.
