data cannot be permanently deleted from the hard disk after deletion of data its image have been formed in the hard disk which can be recovered by using the recovery softwares. if you also want to remove this image of data it can be removed by passing the uv rays through your hard disk...................
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 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.
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.
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.
The remove command is typically used in various programming and command-line environments to delete files, directories, or specific data. In Unix-like systems, the command is often represented as rm, which allows users to remove files and directories with options for recursive deletion and forced removal. In programming languages, similar functions exist to remove elements from data structures or files. The exact syntax and behavior can vary based on the specific environment or language being used.
To fix a disk read error on a laptop, start by restarting the device and checking all connections, particularly for external drives. If the error persists, boot into Safe Mode and run a disk check using the Command Prompt with the command chkdsk /f. If the problem continues, consider using recovery tools to repair the disk or backup your data and replace the hard drive if it’s failing. Always ensure you have backups of important files to prevent data loss.
The attrib.exe -s/s command
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;
