Yes - that's basically what a hard disk is for. Perhaps I'm missing your question - can you rephrase it?
Go onto "My Computer" right click on the disk, and then select "Format" it will not entirely erase all the data on the CD, but it will erase majority of it.
Unused disk space is space on a hard drive (or another kind of disk such as a CD) which has not had any digital information written onto it or is free to be written over. Example: you buy a brand new 100GB hard drive and the only thing on it is your copy of Windows7 64-bit. About 20 GB of the hard drive are required to store the Windows7 operating system on, so you would have around 80GB left that is "free." This is unused disk space. An interesting fact, too: when you delete something by putting it into your "recycle bin" and deleting it, it doesn't actually "go" anywhere. The computer does not go in and actually "erase" that information from your hard drive, it just notes that the area where that information was stored is now "free" to be written over with new information, so this also counts toward "unused disk space."
Simply put, as you put more and more information onto your computer it takes up space on your hard drive. So when it says for example that you have 40gb space free, then this is how much more information you can put onto your disc before it is full.
Burnt the i386 folder from your harddrive onto a disk and that's it.
used for longer term storage of data
A plastic disk with digital information etched onto it.
A writable disk is a disk in which you can write (ie., store) data onto. The majority of diskettes are writable, and so are blank CDs and DVDs. Computer hard drives are generally writable as well.
A computer hard disk drive stores and retrieves data efficiently by using magnetic storage technology. Data is written onto the disk using a magnetic head that creates tiny magnetic fields on the disk's surface. To retrieve data, the head reads the magnetic fields and translates them into digital information. The disk spins rapidly, allowing the head to access different parts of the disk quickly. This process enables the hard drive to store and retrieve data in a fast and efficient manner.
The information is recorded onto the Hard Drive inside a computer.
Well if you have it installed then just try to open it and if you cant then you would have to buy the disk
The easiest way is to use a second party utility like "Partition Magic". If your computer has a floppy drive you can use a windows ME boot disk... a Win 98 boot disk won't read the NTFS partition (if you are running Win 2000 or Win XP)- by running the FDISK utility. IF YOU DON'T REALLY KNOW WHAT YOU ARE DOING DON'T ATTEMPT THIS OR YOU CAN COMPLETELY BUGGER UP YOUR HARD DRIVE!!!!!! hen you will have to pay some one like me to fix it.
Assuming you mean 'why does' - instead of 'what is'... A new hard-drive is literally a 'blank canvas' - there is no information on it. Once physically installed, in order for the computer to be able to 'recognise' it exists, the 'format' command writes information onto the drive - which tells the computer vital information about it - such as it's capacity, number of surfaces and other reference data.
