Hard Disk Drives

when you open your computer you will see that their are about 4-5 diffrent colored cables connected in one spot. then their will be a ribbon cable connected to the left of it. On most computers you will see that the hard drive is located by the CD and DVD drive. After you locate it you will unplug them. it will require some force to take them out. Then if you look to the right side of the drive you will see that it is screwed in so you need to unscrew them. check the left side for screws to and then after that your done. I hope this was helpfull

I suppose by flash drive you are referring to a USB stick. My answer is "yes and no". It depends on the program so to speak. You would probably have a hard time running a complete office install from a stick. I hesitate to discount it completely, because I have never tried. A single executable file can easily be stored on a stick and executed from the stick. You can even have a program auto-execute when you insert the stick into your computer. I believe there have been security issues in this regard on certain operating systems, and you will probably have to enable this feature in your operating system.

The price point for hard drives has fallen drastically over the last several years. The break point now happens between 2 TB and 3 TB. A 2 TB drive runs around $95 while a 3 TB drive runs about $120. By comparison, a 1 TB drive will cost around $80. This makes the 2 TB the best deal for your bucks.

Ideally if you don't already know, you shouldn't be doing it. Especially if you don't know about anti-static precautions. For a desktop: Ground yourself against a radiator or any earthed metal (just hold it for a few seconds) to remove any static charge you may be carrying. Unplug the power supply, open the case of the PC (may require removal of screws or undoing clips depending on the model of PC). Find the hard drive which needs replacing, it should look pretty much same as the one you have to replace it with. If there is more than one hard drive present, then you'll have to check which one needs removing before continuing. Unplug the power connector and the data cable from the back of the old hard drive. Remove the hard drive (if in a caddy you will need to swap the caddy over, which may require removal of some screws as well). Put the new hard drive in (also using the caddy if one was present). Plug the 2 cables back into the hard drive. Put the case back on. Job done!

Over a period of time as some programs are downloaded and others are deleted; your hard drive becomes fragmented with "loose ends" of old programs and when new programs are added, your CPU will stuff parts of the new program into various spaces all over your hard drive. This has the effect of making your CPU work harder when said program is called up. Thus, slowing down the overall performance of your computer. By doing a disk cleanup (defragging), your computer can delete these loose ends and re-position your programs together on your hard drive so that the CPU doesn't have to search all over the disk for a particular program when it is called up.

This is called "Disk Formatting" "Formatting"

1. Importance of medium.

By the 1980s, hard disks had a seek time of ~20ms and today that's just down to ~10ms (on a consumer disk). So for the simplicity of argument, the HD seek time has "just" improved double. Numbers for historical CD-ROM seek times have eluded me, but it hints towards being ~90ms in 2000.

So one idea is simply: CDs were initially just meant for sequential reading of CD-DA. And, later on, do not seem to be considered as important as hard drives, or we would have seen improvements in stepping technology here.

2. Type of interface

Note too however that CDs act using optical means, while a spinning hard disk fares with magnetic - it might have to do something with processing delays, specifically the D2O/O2D converter in the optical components.

3. Caching

Copying a file in DOS always seemed a long business in the 90s on my personal box. There were indeed many seeks involved (and you could hear that). However, I have seen SMARTDRV in use on similar powerful models, and it seemed to make the procedure more responsive (at the cost of memory).

Now, hard disks have gotten more caches over the decades, currently they have something like 2 MB, or even more, while CD ROM drives seem to be still stuck at 128 KB.

read/write head

if you receive a virus or any malware that disrupts your computers functions or stops you from accessing your files, or if the virus is made to delete your files it can disable you access to the info and you might need to reinstall your operating system in this case you would not be able to access your information unless it was backed up. you could also cause physical damage to your laptop or its stolen and unless its backed up you wont be able to access any of your files. Also you should do it time to time so that you are updateing you backed up files with any current files that you recently created

Go to Control Panel and open up your hard drive by double clicking on it. Then inside the window that opened, right click once and select properties. Then select tools and click on scan disk, or error checking. They mean the same thing. You will need to reboot and then the check will start.

Yes, you can change the floppy drive but you'll have to take apart the whole laptop.

If you have no experience taking fixing laptop, I wouldn't recommend trying it.

But if you still want to try it, I'll post a link with Toshiba laptop disassembly guides so you can try.

The items which cannot be repaired are consumable items and if repaired, the costs of which are more than the cost of item will be treated as consumable item.

No formatting a conventional hard drive does not slow down the hard disk.

When we talk about formatting, this means the removal of all data on the disk as well as the operating system (OS). This is often done in order to reinstall a faulty OS or to install a now one.

Basic formatting of the drive deletes the file allocation table leaving the drive "empty" to be installed over (similar to a major delete, but without the recycle bin option); low level formatting of the drive (normally done through the motherboards ROM system) "wipes" all contents of the drive.

I suppose the notion of formatting the drive and slowing it down comes from the fact that the read/ write function performed by the disks heads may in some way damage the disk. This is simply not true.

HOWEVER, solid state drives should not be continually formatted and should not have any form of optimisation software run on them. They work according to different principals (as opposed to a magnetic drive), and continual reading and writing of data to the sectors does actually cause them to become "worn", the entire cluster is then no usable; the unusable clusters are stored in a portion of the memory so that the computer cannot access them and try to store data over the "bad cluster". The same applies to flash drives as they are a smaller version of a solid state drive.

A zip disk is a disk which can be read by a Zip drive.

The hard disk drive stores information on the computer. It has read and write capabilities and the information stays there when the computer is turned off.

a disk drive is a hard drive on your computer for memory storage. all computers have them, its where my documents is and all your files, although you can buy a second or third or fourth disk drive. its just the way a computer reads a memory card or hard drive

Generally speaking, only one. However, there are some devices, known as "port multipliers" that will allow you to connect up to 15 devices to a single channel.

You cannot do that. SATA and IDE are not compatible. What you can do is to buy special expension card which can work with SATA drives. For instance,
