Data recovery is the most useful and by far the best way to retrieve data that has been lost or deleted from a hard drive. Hard drive recovery can restore files that have been lost, no matter what the cause may be. From viruses to crashes, data recovery can restore the files on your hard drive by rebuilding the platters and the structure of the drive. Before you hard drive can be rebuilt, it must be evaluated. The evaluation process will give the technician a chance to go through your hard drive, determine what caused the failure, and what they need to do to restore your data. This is a very extensive process that involving a series of steps performed by the technician.

First things first, the technician must determine if the problem is logical, physical, or possibly a combination of both. Physical failures result in hardware malfunctions, while the logical problems lie in the software. Once the technician has found the problem and the cause, he can plan out the repair process and what he needs to do to recover the information.

If the technician is able to gain access into the hard drive, he or she will then create a mirrored image of the drive and continue the process. The data structure will come next, where the technician will determine just how much of the data can be saved. This step in the evaluation can be the most time consuming, as the technician or technicians will have to go through each sector step by step and located what data can be retrieved and what data cannot be retrieved.

Today, most digital pictures and family photo albums are stored electronically on a computer. These electronic images are much more vulnerable than traditional paper albums. Images could disappear from your PC if the system is attacked by a virus. An entire photo album can be deleted or corrupted by faulty software. Digital pictures can disappear from a memory card if you remove it from the camera when it saves your most recent snapshot, or if the operating temperature is too hot or too cold for that particular memory card. Is this a problem? Not at all! You can always restore lost pictures easily with Magic Photo Recovery!

An easy step-by-step wizard recovers digital pictures lost or deleted from hard disks, digital cameras, memory cards and a variety of storage media in a quick and effortless manner. Deleted a photo from your computer or removed it from your digital camera? No problem! Magic Photo Recovery will scan the entire disk or memory card to locate and recover every picture you deleted. Formatted a memory card or repartitioned the entire hard drive? No problem! Magic Photo Recovery recovers images from disks and flash cards even if they were repartitioned and reformatted several times. Magic Photo Recovery recovers images deleted from the Recycle Bin or lost after a system failure, reads pictures from formatted or corrupted memory cards, and can even recover digital pictures and RAW files directly from the camera!

Cabling your home for computer network – still a requirement?

With proliferation of wireless networking and communication equipment it is oh-so-tempting to cut the cord and save a significant sum of money in the process. But is everything that a regular computer networking user needs can be done using just wireless network? Let’s take a look at some pros and contras:

1. One important advantage of having a cabled network is the available bandwidth or simply speed. At the present point in time the speed of connection via a simple and inexpensive CAT5E cable can be 1000Mbit/sec, whereas the best that IEEE802.11g (one of the many flavors of Wi-Fi) can offer is only 54Mbit/sec. It may not seem so significant if you think you are only browsing Internet, and the DSL speed available to you is 1.5Mbit/sec. However, if you need to print via your network connection on a remote printer, you should realize that the print jobs, depending on the amount of graphic data in them, can easily reach dozens and even hundreds megabytes. Since 1Byte=8bit one 100MByte print job will take 15 seconds (and in reality this time can be much longer) to transmit via a Wi-Fi wireless connection, and this time shrinks to mere 1 sec or less on wired 1000MBit/s Ethernet connection. Same principal applies to transferring files, backing up files on other computers in the network etc.
2. It is not possible today and with all probability will not be possible in the future to transmit power needed for your networking device via the wireless link. Unless, of course, you would be willing to be subjected to very high levels of microwave radiation. Thus a device that was marketed to you as “un-tethered” will in fact be very much tethered via the power cord or will have to be re-charged every so often. The power requirements are increasingly important for devices that are expected to be always online, such as phone sets. Therefore it is best to have it connected via a cable that can deliver both power and the communication signal at the same time.
3. Wireless communications are very much proprietary and require whole gamut of conversion equipment to transmit multi-media signals. The same CAT5E cable can without any modification support phone, computer network, balanced line level audio signal, baseband video signal as well as host of other, more specialized, control applications’ signals. With inexpensive adapters called “baluns” the same cable can carry significant number of channels of broadband television or carry a baseband video, such as security camera output, through great distances. All of those applications, except the computer network of course, will require specialized expensive conversion equipment if they needed to be transmitted via a Wi-Fi link.
