How To Recover Data Or Survive A Hard Disk...
disk drive (HDD, or also hard drive) is a fixed data storage device that stores data on a magnetic surface layered onto hard disk platters. A hard disk uses rigid rotating platters (disks). Each platter has a planar magnetic surface on which digital data may be stored. Information is written to the disk by transmitting an electromagnetic flux through an antenna or read-write head that is very close to a magnetic material, which in turn changes its polarization due to the flux. The information can be read by a read-write head which senses electrical change as the magnetic fields pass by in close proximity as the platter rotates. Disk failure occurs when a hard disk drive no longer[..]
With proper computer maintenance and repair,...
Removing unwanted files from the system, optimizing the web browser, installing only the necessary programs, and keeping the computer safe, are some of the ways in which a computer can be maintained well. Though trained computer technicians handle computer maintenance and repair, they are, in a sense, antithetical functions. It is so, because a computer that is well maintained is unlikely to need any repair worth the name. However, one that is badly maintained will be in need of frequent repairs. Computer technicians, whether it is an emergency repair required by some major problem, or even if it is routine computer maintenance repair, handle any form of computer repair. But the[..]

TIC TAPE STORAGE Beginning in the 1950s, magnetic tape has progressed from the original half inch wide ferrite coated tape on open reels 10inch diameter and 2400ft long to the current cassettes mounted on drives in stacks. The first drives recorded 7 bits across the tape, being 6 data bits + parity. This was increased to 9 bits to accommodate the 8 bit byte, the backing medium was changed to mylar for strength, and allowed 4800 ft to be placed on the reel with thinner tape. The main change was in the recording systems. The first universally adopted 'standard' was NRZ (Non Return to Zero) referring to the crossing from negative to positive of the magnetisation at speeds up to 800 BPI. The[..]

Backup And Archive For Photographers
Based Workflow Your file based workflow has many advantages compared to traditional film and slides. All your images usually stay on the media of your choice, like hard disk, CD, DVD or data tapes. Most of the time, they reside on a hard disk for fast access. This, however, brings the risk of accidentally deleting files. Drives can also be affected by file system corruption, malware, viruses and hardware failure. As a result, managing your data is necessary to safeguard it. Backing up data means duplicating them. This reduces the risk of hardware failure tremendously. Most of the above mentioned risks are still present if you use a hard disk that is continuously on and connected to your[..]
tart --> The acronyms are mirrored, and each shares two words - network and storage. However, NAS and SAN differ greatly in design and implementation, and therefore represent distinct solutions in terms of what Intel® data storage system is right for certain business applications. Safe and efficient data handling is a necessary measure for a business that wants to implement a successful storage and backup plan. Intel® has developed several storage solutions with that in mind. One is not necessarily better than the other; the preferred storage method simply depends on a company's needs and existing infrastructure.

We have made reference to computer memory several times in this series, history of the computer, now it is time to look at how it has developed, and is still developing. A look at a block diagram of a modern PC will show how the memory is central to the way a computer operates. Everything passes through it. Many would say the processor, or CPU is the most important part, but you can see that everything depends on the memory. The easiest way to improve the performance of a computer is to add more memory. The layout of the PC is much the same as the original digital computers. They didn't have monitors, or optical disks, but they had control panels, a teletype, for operator communication,[..]

DATA TRANSMISSION CODES We have mentioned teletype machines, these were the backbone of operator communication with the computer, but were also used for remote input of data. A phone line could be used to link a storeman in the warehouse with the main computer using a modem (Modulator-Demodulator) in much the same way you dial-up to your ISP (Internet Service Provider). These modems typically worked at 110 Baud, the standard speed of the teletype, and sent or received one character at a time. They modulated the carrier on the telephone line in a string of bits in serial pattern (one after the other) for the code, usually ASCII, complete with start bit, stop bits (1 or 2) and negative or[..]

Lifetime of a CD-ROM disk
How Long Will a CD or DVD Last? As with any backup medium (floppy disk, tape, CDROM, etc.) the lifetime of the data is an important consideration. Kodak has done extensive accelerated aging tests which indicate that their Infoguard CD-R should last 200 years. TDK say that their discs will last "about 100 years". Others tell horror stories that no-name CDs which they have burned are no longer readable after a few months. Optical disk manufacturers advise that storing your backup disks in a cool, dry environment will help to prolong data life, while direct sunlight and fingerprints may cause damage to a CD or DVD. A good rule of thumb (no pun intended) seems to be to buy a brand-name[..]

Data loss is not something that anyone wants to live with. After all, we have all become so dependent on the electronic forms of our data. And yet, despite this dependence and the fact that we are fully aware of it, we often neglect to back up data. And thus, when the medium where our data is stored becomes damaged, we have no choice but to resort to data recovery services. It would have been better and easier if we developed the habit of backing up our data. After all, there are many options available to us to do so. How Data Loss Can Occur As stated above, we have become fully reliant on the electronic forms of our data. Our photo albums are now stored as jpeg files in folders[..]
Hard drive capacities has been increasing year after year and we are now reaching unprecedented capacities. The question I pose to you is how much space do we really need? My first computer I owned was in 1994. I had a 100mhz computer with 500 MB of disk space with a cost of nearly $3,000. Could you imagine having a hard drive today with 500mb? It did its job back then with only 500MB, but there's no way you could even install an operating system on it today. 6 years later (in 2000) I decided to upgrade my computer storage space. It was a 60GB hard drive that I paid well over 500 dollars for. Yes I know that sounds a bit crazy, but at the time the average disk space was about 10-20 gb,[..]
