Hard disks or sometimes called hard drives allow the storage of huge amounts of data on an electromagnetically charged surface or set of surfaces. A hard disk is actually composed of a stack of disks similar to old phonograph records where data is recorded in concentric circles known as tracks. The disk drive head records and reads information stored on the tracks. There are two heads located on both sides of a disk that either reads or writes data as the disk is spinning. Every read or write event needs for the data to be located which is known as seek operation. Hard disks come with varying speed and mapped to logical block address (LBA) which is commonly found in larger hard drives.
With the introduction of the Compact Flash Adapter, anyone can now make use of a CompactFlash memory as a primary hard drive function for a computer system. As opposed to the traditional hard drive, this has no moving parts like spinning disks or wobbling bearings. This gadget provides the functionality of replacing traditional hard drives with economical and rugged CompactFlash cards that uses the same IDE motherboard interface like regular hard drives. Any system equipped with a standard 40-pin IDE connector can use this technology. This solution does not require the installation of additional hardware drivers and can be used as a primary boot device that contains the computer’s operating system.Filed under Related Ideas | Comments Off
Of course, everybody wants more capacity. If you have the money to spend, why not indulge into it? Just a little upgrade will be nice. You will find no difficulty upgrading your IDE hard disks, either by replacing the old one or adding another one to add more space.
All IDE hard disks have the same standard pins and socket type. So if you are just replacing a hard drive, the steps can be very easy. Just plug out the IDE and power cables from the disk, remove the screws holding the drive into the case and plug in the new one.Filed under IDE Hard Disk Instructions | Comments Off
Stressing the needle because of defragmenting has some truth in it, though gone astray. Defragmenting the hard disk might require a lot of searching and looking as the hard drive reorganizes its data in a contiguous style. Defragmenting lets the read-and-write heads to scan huge amounts of data without searching over the platters.
On the other hand, right after defragmentation, the hard disk is no longer required to search for all the platters for your data. In this way it lowers the amount of head actuator actions as well as intensely increases the performance of the hard drive. For that reason and technically, defragmenting the hard drive will reduce the workload of the head actuator.
By now you might know that “deleting” a file does nothing of the sort. However deleting a file on the disk drive disk drive has a built-in system for the secure erasure of data?
A directory in the hard disk is programmed in the system where the file data can be found. The delete process, all it does is to erase the file’s reference information. The operating system can not find it, but the data is still present at the hard drive.
The File recovery function is up to this task. This program looks for the data in the block directory. If the PC is keeping confidential data on business, medial, and other personal financial information a simple deleting command is not enough when disposing the equipment.Filed under IDE Hard Disk Basics | Comments Off
This is an error message we all hate we’d never see but these small yet terrible precision storage devices are electro-mechanical and they will eventually wear out. Before you consider burying the darned thing, try getting hold of a new IDE cable and replacing that. The cable is made up of several dozen wires that tends to cook up in the PC’s case especially if you don’t have ample cooling and you love to over-clock the system that makes it hot enough to cook and egg on.
Another thing you might want to try is to unplug the IDE cable at both ends and try re-seating them. The heat within your PC causes thermal expansion which can loosen cables(though very rare), but they can happen. check the power connector and switch with another one or a free one you may have. Of course you’re doing this all after you’ve shut it down and pulled out the plug from the wall socket, waiting a few minutes for the residual charge in the power supply to dissipate. you should also touch the power supply to get rid of the very nasty static charge you maight have picked up walking on your carpeted floors.
There was a development undertaken a few years back that was geared towards creating a control chip to be utilized by system independent IDE host adapters. The Epson QX-10 was one of the devices used in this experimentation wherein it was fitted with an IDE hard drive. The developed interfaces were primarily simple in order to make some minor BIOS setting changes easy. A Western Digital WD1002-HDO was used with 95% of its driver routines being able to correctly control the function of the hard drive. The minor revisions done included the addition of a single sector number to the IDE where it starts at sector 1 instead of the default sector 0.Filed under IDE Hard Disk Bits and Pieces | Comments Off
Although IDE hard disks are not yet obsolete, we have to face the truth that is has long been ousted from being the standard, having been replaced by the much faster SATA. And with technology advancing continuously, we can only guess how long the SATA will hold its place, especially with solid state drive now being used as hard drives in laptops.
If you are still using IDE hard disks, it is useful to know all you can about your hard disk. But it will be equally useful to start thinking about upgrading your system, or at least backing up your data in an external hard disk or even online via cloud services so that once your hard disk gives, you won’t be at a loss on what to do. While it is commendable that you aren’t buying into consumerism and using your hard earned money to invest and trade in the Forex instead of buying newer computer units each time a new model comes out, your old one is bound to breakdown sooner or later.

Anytime bad sectors of the hard drive will suddenly appear whether you just plain using the hard drive or formatting it. The number of bad sectors is definitely will increase as the time goes by.
This myth has some truth in it though. After formatting bad sectors are probably noticeable. This happen because in formatting in formatting the hard drive utility looks for the “new”You will probably notice more bad sectors after formatting. Consequently bad sectors are already there and what happen was revealing them.
So, in a failing hard disk the number of the bad sectors will not increase when you format it. Bad sectors are being revealed in doing so.Filed under IDE Hard Disk Bits and Pieces | Comments Off
Look at your workplace. Have you ever wondered how you can get rid of all those wires hanging around? No, I am not saying that you must go wireless with all your things as you might spend a lot of money on buying new gadgets when in fact the old ones are still working. You just have to be a little organized about your home wiring system as this may cause a lot of accidents. But believe me, even if you decided not to go wireless, your workplace can still be as organized as you can imagine.
How about getting some of those docks made by Unitek? They are currently selling in the market a dock wherein a lot of computer gadgets can be connected. Aside from the 4 card reader slots and the 2 USB ports available, you can even insert an external hard drive in it.
