You should perform regular backups of a hard drive at least weekly.
Daily backups are ideal.
weekly
at lest weekly r u sure? may anybody comfirm.. plz?
Yes.
I am guessing you mean "Do backups stay in the PC after Format?" The answer is No, if you store the backups of the files on the same hard drive you are formatting. Its not technically a backup then anyway. To make a proper backup, you need to copy your files to a USB key, burn them to a CD or DVD, or copy them to another computer or hard drive.
I don't believe you can recover a file from a USB drive if you don't have the USB drive. I keep backups of the files.
external hard drives
Making backups is a very important task that we should make regularly because unexpected things can happen such as hard disk crashes, unintentional file deletions. Sometimes failures can even happen for unexplainable reasons. Making a backup to a removable drive or use online storage is very important.
Backing up a drive is a great way to ensure your data is preserved in case of hard drive failure or accidental deletion. Here are the steps to back up a drive: Connect the drive to your computer. This can be done through a USB port or over a network. Download and install any necessary backup software. This will allow you to easily select which files you want to back up. Select the type of backup you want to perform. This can include full drive backups or individual file backups. Select the destination for your backup. This could be an external hard drive an online storage service or a secondary computer. Start the backup process. Depending on the size of your drive this could take several hours. Verify that the backup was successful. You should be able to open the files from the backup to confirm that they are intact.Following these steps will help you back up your drive quickly and easily. By taking the time to back up your drive you can rest assured that your files are safe and secure.
Regular backups of your data is the best strategy for avoiding a computer disaster. Store the back up in an offsite location, such as a friend's house or safety deposit box. This will allow you to restore your data if your hard drive is completely dead.
Create a disk backup of your hard drive so that in case of a hard drive failure, you can restore your computer to the exact state prior to the failure. NovaBACKUP Professional will create system images, exact backups of a disk drive sector by sector, allowing you restore backups to a computer when the contents of the entire computer are lost.
You didn't mention if this is a floppy disk drive, a hard drive, a CD drive or a DVD, but the answer is the same in most cases. Don't bother to repair the drive, because disk drives are so incredibly cheap these days anyway. Replace it. If this is a hard disk drive containing critical information, then you should look for professional help to recover data from the disk, and then replace it. Hopefully you have backups.
