Assuming you only have 1 CD drive, you will need copy the data to your hard disk (or possibly a flash drive), remove the original disk from the CD drive, put the blank in, and burn the data that you copied to your hard disk.
The easiest way is to use the 'rm' command recursively. For example, the command: rm -rf /data/test/docs/fall would remove the directory 'fall' from /data/test/docs, even if it isn't empty.
The harddrive stores data on a single magnetic disk, somewhat compareable to a CD in the way that it spins, its round, and it stores data. The "head" of the harddrive uses magnetic fields to excite different areas of the disk to store a binary code such as "00100010." Millions upon billions of these codes are stored on the disk with each code being a single command.
We can burn a disk when it is an re-writable disk even though it has data in it.But when it is an ordinary disk i.e., if it is an only writable disk with data in it,we cannot burn the disk with another data.

If you are using the word "assessing" to read a disk then the amount of data you can transfer to the disk (write) is the remaining available free space on the disk. On the other side of the coin, the amount of data to can extract (cut) is the amount of data that is stored on the disk.
A hard disk acts as a storage device for data. Data is also retrieved from the hard disk. The data that is kept in the hard disk is not erased even when the computer is switched off.
When you do a data export, or create a table, move a table, move a file, ftp a file, etc., you need to specify in the command where the data will go. This is the "destination" disk. This disk will be a named object. My disks are called: $D001 $D002 So, my create table statement would include the disk specification in the statement: create table $D001.VOLUMENAME.TABLENAME field specs table attributes;
