Hard Drive Myths part 2
Bad sectors of the hard disk will not cause by insufficient power of power cuts. The head actuators automatically park the heads on every occasion there is power cuts so that the platters won’t crashed to head actuators. There is no way that power cuts will cause your hard disk bad sectors but having a bad power supply can fail your hard drive because it will surge the circuit board of it and may fry the motor.
A cheap power supplies do not kill hard drive even slowly killing it. That is a myth. Like any other power supply, when it send and surge the hard disk the disk will be instantly kill.
Hard Drive Myths part 1
One sign of the hard disk’s calibration process is the spin-up and spin –down events. The hard disk recalibrates itself to balance the changes in temperature which is also adjusting the position of data on the platter surface and when the hard disk can not scan the data properly. As a result, if the hard disk recalibrates a lot it might be a symptom of a failing hard disk.
However, take note that there is hard disk that programmed to saves power. In order to saves power the hard disk spin down and when there’s work to be done that’s the time to spin-up again.
Going all the way in protecting your files.
If you have very important documents or files in your current hard drive, have you ever wondered how you can really “protect” your files from being destroyed? Of course, there are a lot of ways on how you can protect the files inside such as encrypting the drive with a password or buying one of those hard drives with fingerprint recognition. However, having these can only protect what’s on the inside. Have you ever thought of protecting the outside?
Sentry(R)Safe cared so much about protecting your precious files that they made a gadget that is both water and fire proof. The hard drive has a 160GB capacity and was given a lot of awards by some of the most known companies and critics in the world of technology.

Feeling a little unsecure?
If your business or job calls for secrecy, then you might want to store your documents in a safe place. Of course, our generation has already given up on manual storage and we let have let computers do this tedious task for us. However, there are some security risks when we store soft copies of our documents in a hard drive. First off, you must create backup copies of your documents. We will never know when your hard drive will fail you. Second, you might want to invest on hard drive security. Chinavasion has made a step towards this kind of security. They made a hard drive that can only be accessed with fingerprint recognition. The hard drive can recognize as much as 10 fingerprints, and so you can actually limit the access of your files. Fingerprint recognition can in fact be more secure than password encryption because hackers nowadays are becoming more ingenious.

How Much is Enough
The ability to connect a specific hard drive is generally limited but he architecture of the motherboard and bios as a matter of fact with most today limited to 500GB in capacity. Attach a larger drive and you may not be able to utilize the full capacity of the drive which you may find out in the detected drive displayed within the BIOS setup screen. Though most motherboards now use auto detect, detecting and getting the information about the hard drive from the internal electronics, there was actually a time when you had to know the parameters of the drive for one to mount it and use it properly. IDE today has become an older standard, replaced by SATA which has faster transfer rates and other speedy attributes. They also have a slimmer connector that lessens the restrictive effect the former 80-wire flat cable had on the overall computer system. Continue reading »
Hard Drive – Size does matter
Hard drives come in many forms and shapes, the most common are the 5 1/4″ and the 2 1/2″ the first appearing on desktops and the later on laptops. As of this year, the highest capacity hard drive has topped the 2TB capacity and is set to improve further as data storage technologies improve. The smallest hard drive ever made was a 0.85″ hard drive developed by Toshiba for use as if it were an SD/MMC card for data storage on a computer or mobile devices. The two forms of hard drives have stood the test of time due to the fact that flash memory has experienced such a boom prices have fallen making them a more viable storage solution for smaller needs. The speed at which these drives spin can range from 5,400 to 7,200 rpm the later of which was the long standing standard for server-type SCSI hard drives that were very expensive. Most mobile computers (laptops) come with a 5,400 rpm drive due to the sound considerations when using the device, the faster the device the louder the sound (the spinning sound or hum you hear). You can in theory use faster hard drives on mobile computers but they would reduce battery life and make it noisier defeating the overall design of the laptop. Continue reading »
S.M.A.R.T. – Saving your data before you know it!
SMART is a monitoring technology build into the electronics of hard drives as a way of the computer monitoring it’s performance and may give warning of pending failure. Though the system is generally one that works without a hitch, it cannot protect you from sudden hardware failure which leaves the drive non-operational. Sudden hardware failure is estimated to account for 60% of all drive failures, and is attributed to rough handling or drops and knocks say a laptop falling onto the floor from your desk. They are designed to withstand specific amount of impact force (measured in G’s) that means a hard drive may survive a fall from a 3-foot desk. Continue reading »
Two essential tips
1. Run Disk Degragmenter.
You can find it in Start > Program Files > Accessories > System Tools. Disk Defragmenter effectively sifts through your files and organizes them, thereby saving you hard disk space as well as speeding your system up. Since it takes a long time to get done, it is recommended that you run Disk Defragmenter just before you have a task or errand to do so you don’t have to endure the long wait.
2. Use a hard disk fan.
Electronic processes generate a lot of heat for the hardware, which is ironic, since heat is the major factor in the degradation of computer equipment over time. Especially for bigger and faster hard disks that spin at faster rates, you need a fan to help dissipate the heat and make your HD last longer.
MTBF – Meaure of Reliability
Mean-Time-Between-Failure or MTBF is a term used to describe the reliability of the parts of a computer system from a technical standpoint describing reliability and is measured in hours. The higher this number the more reliable a computer part is. with respect to hard disk drives, particularly IDE drives this denotes the number of hours before it fails or parts of the electronics, motors and bearings can last without any failure. This is an older measure used by the computing industry when hard drives were still quite steeply priced with the best ones reserved fro use on servers and other high demand uses. Ide has long been replaced by the SATA standard which eliminates the thick IDE cable that blocks airflow within a computer’s casing preventing proper cooling.
