Which one is true for unconditional disk formatting? A. Destroys every byte of data on a disk by overwriting it with blank spaces B. Do not check/scan surface after format C. Transfer system files after format D. All of above

The correct answer is D. All of above.

Unconditional disk formatting is a type of formatting that destroys every byte of data on a disk by overwriting it with blank spaces. It does not check/scan the surface of the disk after formatting, and it does not transfer system files after formatting.

Unconditional disk formatting is typically used to erase sensitive data from a disk before it is disposed of. It can also be used to prepare a disk for a new operating system installation.

Here is a brief explanation of each option:

• A. Destroys every byte of data on a disk by overwriting it with blank spaces: This is the main purpose of unconditional disk formatting. It ensures that all data on the disk is completely erased and cannot be recovered.
• B. Do not check/scan surface after format: Unconditional disk formatting does not check the surface of the disk for errors. This can be useful if you want to erase the data on the disk quickly, but it means that you cannot be sure that the disk is in good condition.
• C. Transfer system files after format: Unconditional disk formatting does not transfer system files to the disk. This means that you will need to reinstall the operating system on the disk after formatting.

I hope this helps!
