Always have a hard drive failure? I. Here is my story:
I placed my late 2009 MacBook Pro Apple to sleep late on a Saturday night. As late at night I have not had the time or the patience to let my computer completely off and have little light in a short time ago, indicating that he was asleep. I jumped the gun and turned my computer on the right side is the hard drive is still running. Some NO, NO, according to Apple. You need to stop the hard drive and wait for the light to vibrate.
The next morning I woke up, ready to enter the new page that I developed for my dive photography business. My Macbook Pro awoke without incident and I thought everything was ok. Adobe Lightroom and do not save a file, I worked. He said he needed a place to store the files I was working. I said, “You moron have a place, it means the hard drive.” I restarted as I do, when things is not working well and what I saw next to him was buried in my memory. FILE terrible flash and the question mark. This means talking to Apple, something is wrong. I was later told Apple “genius” to me it was my hard drive. He wanted over $ 200 with taxes for the repair and yet I would not be able to recover my data without having to send my computer into a data recovery service. NO WAY!
So I did it myself and have all my data for less than $ 100. Here’s how: » Read more: How to Install a New Hard Drive in a Macbook Pro

From the beginning of the personal computer (PC) people need external storage media. Below we discuss the beginning of the external memory (disks) to existing technologies. At the beginning of the PC, there were only floppy disk drives, the 5 1 / 4 “were wide. The operating system and applications needed to be loaded into the disk, only the computer to run in the early 1980s. The hard disk of the computer allows the applications be loaded into the computer without a floppy drive. During this time, people could store their information on those disks and keep it off-line are loaded into the computer later.
The original 5 4.1 “floppy disks instead of 160KB (kilobytes) of data, but improved rapidly to 360KB. To put into perspective this is 1KB about half a page of text. Floppy drives have been pursuing from a vinyl record in what is where the data was stored. 5 1 / 4 “disc is 1.2 MB (megabytes) limits, but still contained in the disk fragile was the subject of environmental contamination. The format of the next was going to be 3 1 / 2 “floppy disks. These were not only smaller, but they had a plastic casing to protect it. Although she started only 720 KB are organizing to data, they were soon in should be capable to 1.44MB of data, and were much easier to save in the cases and off-site. In the late 1980s, the 5 1 / 4 “floppy disks replaced by 3 1 / 2 were” format.
During the same period in the 1980s, is the internal hard drive to a standard PC. There are clear differences between the hard-disk space (think library of information) and memory (RAM – Random Access Memory) and the floppy drive (used to carry information). Hard disks have a 5 1 / 4 size 5 MB “Memory (MB) of data began in constant growth in the 1980s to the disc Quantum 1.28GB. To put it in the right light is about 1 GB 250 MP3 songs. Unlike floppy disks, hard disks were installed in the computer. Hard disks continue to shrink form factor up to 3 1 / 2 growth “in the 1990s. These drives are called half-height drives. In the 1990 drives were quickly growing from around 40 GB (gigabytes) of total memory all the way up to 3TB today (terabyte) drives.
Hard drives continue to shrink with the standardization of notebook models 2 1 / 2 form factor. “Disk drives in an external housing, while about a technical for some time in the consumer market in standard formats such as USB (Universal Serial Bus) was, FireWire and SATA (Serial AT Attachment), although the year 2000 allows. These new formats these must be quite portable speakers with a standard interface (like USB) to connect to another system without pain. USB socket allows more generic and the game is to allow the system to disk, once identified, how to . connect There are some fields on the market that can accommodate multiple hard adrives and be able to RAID (redundant array of independent disks) capabilities. RAID offers the option to either mirror your data from one disk to another or elongation (strip ), the data on the disk you have. What this offer is a failsafe in the event of loss of a hard disk, because the failure of the computer will not notice any difference in access to take your data on the hard disk of other players. » Read more: A Brief History of External Storage Devices – From the Floppy Disk to the Hard Drive
