These are units of storage capacity, not performance. Hard drives can read and write data faster if the platters spin faster. The number of platters will also greatly affect your read and write speeds. Assuming that both drives spin at the same speed, have the same number of platters and are the same physical size, the 120GB hard drive will be slightly faster. It probably won't be noticeable. In terms of storage, 80GB is often much more than a user will ever need, despite the average drive today being hundreds of gigabytes in size. Unless you have over ten thousand mp3 files, have many bleeding-edge games or store DVD quality movies, the extra 40GB will not affect you at all.
How do you erase hard drive before give it away?
Please what ever you do, DO NOT simply do a format of your hard drive. Reason being, with the right software, anyone can retreive any / all data that is on the drive. People may think that after a format, everything is lost, but this is NOT the case.
Depending on the manufacturer of your hard drive, I would firstly go to the manufacturers web site, and download their own proprietary software, for zeroing the drive in question.
By zeroing the drive, the program writes multiple 0's across every sector of the drive, thus stopping everyone but data recovery companies from recovering any data on the drive.
If the program offers a quick or extended write, imo i would opt for the extended one every time. It does take around 2 hours to complete fully, but you know everything is gone, and its safe to donate. If you opt for the quick erase, it usually zeroes the first and last million sectors on the drive.
Alternatively, you can download a program called kill disk. Instead of opting for the manufacturers solution, this will work on any drive.
Hope this helps.
If you need any further assistance please don't hesitate to contact me.

Yes, but ...
-you will need to remove the 128 MB module and replace it with two PC133 SDRAM modules of 256 MB each. The documented maximum RAM capacity is 512 MB
-you will need to disable the on-board VGA (if any is present) and put an AGP 2x or AGP 4x video card in the AGP slot; AGP 8x is NOT supported
-for a SATAII hard drive, you will first need to add a PCI card with a SATAII controller. So you should have at least 1 free PCI slot.
What are the Negative effects of formatting a hard drive?
The effect of formating a harddisk with the Windows operating system is reprogramming the harddrive into the NTFS file system. This system basiaclly assigns sections of the harddrive to save data most efficiently. The quick form of the format simply erases all the data. In BOTH cases all data will be lost and will never be recoverable for the lifetime of the harddrive.
Why is a hard disk non volatile?
Because any data written to a hard drive will be retained almost indefinitely after the power is removed.
Was there any power going to the tower at all?? Could you hear the fan / drive spinning??
If not, then quickest way, is to check the power lead. If this is working, then it could be the PSU that has gone. If it is, change the psu over...
If you could hear fan etc, then check the lead from the monitor to the pc. Make sure its installed correctly.
Is your graphics onboard, or a graphics card? What colour light was on the monitor?
All of these questions, will help determine the correct answer.
Hope this helps. If I can help any more, please don't hesitate to shout.

How do you install an OS on an external hard drive?
Drop the install disk for the OS you want to install into the CD drive and reboot the computer. It sometimes is not that simple. The previous answer only works if the BIOS has been set to read the CD-ROM drive before reading the hard drive. The boot routine in the BIOS (hardware chip) will boot from devices in the sequence that are set in the chip. Depending upon your computer, this sequence may be set to (1)floppy/hard drive (2)CD-ROM/hard drive (3)floppy/CD-ROM/hard drive, and so forth. You are responsible for setting this sequence if it is not satisfactory for your needs. Usually, as the machine is booting, for the first few seconds you will see a message on the screen such as, "Press to enter Setup" or "Press F5 to enter Setup" or some such message. Some less robust machines will give you no indication of what to do or when. If you have your computer hardware manual, it should tell you what key to use to enter Setup. If not, try rebooting BY TURNING THE MACHINE OFF AND THEN ON AGAIN and guessing at the the key by repeating it a single key 2 or 3 times a second during the boot process until the Setup menu comes up. The most popular keys that BIOS manufactuers use are , and , although I have seen some use the bar and the key. None will use the regular keyboard keys, such as letters, numbers or special characters. Once you are in Setup, different BIOS manufacturers have different panels to change their settings. Just follow the instructions. Some use the up-and-down arrows, some use the left-and-right arrows and some use the Tab key to move between fields. They will tell you on the screen. After you have made the changes to suit the sequence where you are booting from, MAKE SURE that you select the option at the end to SAVE your changes! Or you will have wasted your time. Conversely, if you think that you have screwed something up, just don't save it, and start over. At boot time, the computer will now look at the first device in the Setup table to see if the media on it has a boot record in front of it. This is called a bootable device. If it does, then it will boot from it. If it doesn't, then it will go to the next device in the table to try again. It will keep trying until it has exhausted all devices and then just stop with a beep-beep. If this happens, then you know that the BIOS is not set up correctly or yoy don't have bootable media in a drive in the Boot sequence. One word of caution, sometimes malicious hackers may have planted a worm on your hard drive. When you re-install the Operating System, MAKE SURE that you use the option to reformat your hard drive during the install. Some OS's will just do it; others will ask you so that your data can be saved. If you have data that needs restored, I recommend that you back it up to a floppy or other device before re-installing the OS and reload it later. Don't worry, viruses and worms cannot hide in data, only in executables. This might be more than you need if your boot sequence is already correct, but I have re-installed hundreds of OS's, and about a fourth of them have viruses or worms on them and another one fourth of them do not have correct boot sequences. You might be lucky on both counts. Good luck!

How does TCP ensure reliable data transfer?
There are three features that allow TCP to reliably and accurately track the transmission of data from source to destination. They are flow control, session establishment, and numbering and sequencing.
What disk can store the most data?
Blu-ray disks can hold quite a bit of data on them, depending on how many layers, they can easily store anywhere between 20gB to 200gB worth of data. DVD's hold the next most, maxing out at around 4.7gB worth of data. CD's and data disks can roughly hold less than 1gB worth of data, usually around 700mB.
What does the performance of a hard drive affect?
The three most notable things that hard drive performance will effect is:
How can I delete a file that won't delete?
Go to the YouTube video I am linking to below. Or search for "file won't delete" in the search there, more than one way to do it.
First of all, I've tried deleting it by dragging it to the recycling bin, which doesn't work. I've tried Shift+Del on it, and it doesn't work. I've even booted my computer in safe mode with command prompt and tried deleting it with the command prompt, and it doesn't work.
Every time I try deleting or even moving it, it just shows the load window, but doesn't have the bar moving... It stays like this.
I've tried leaving it on over night, and nothing is different.
I'm on Windows Vista. Help!
Why is cache memory more expensive than hard disk?
as the cache memory is mory faster than RAM or hard disk ,but the main reason is that the cache memory has comparator and storage medium at the same time, the comparator checks if the address of the value being accessed is in the associative memory(a part of cache)or not, and the ordinary memory(another part of cache)has the data....

How many logical drives can be created on a fat drive?
When you partition a hard drive into two or more partitions (storage areas) those extra drives are called logical drives. So you can have 2 or 3 or more logical drives on one physical hard drive. It varies.
The Hard drive or disk, is the actual system you are using. In my case it is Windows 7 Ultimate. On most computers it will be be your D drive, and should never be tampered with, unless you are qualified to do so, as you can cause severe or terminal damage to your system. It is sometimes refered to as your Motherboard.
