Here you can fully understand the difference between initializing disk and format disk, and get a confirmed answer to 'will initializing disk format it?'. Do not hesitate to download EaseUS Data Recovery Wizard to recover data in case you have very important data on a disk that is unknown and not initialized.

Will initializing disk format it?

"What does initialization do to a hard disk? Please give me a hand. When using the Windows disk management utility, I receive the instruction showing as you must initialize a disk before logical disk manager can access it. The disk is NTFS 100% data with no operating system on it. I'd like to know if it is safe to go ahead and initialize the disk. Does initializing a disk format it? I am not expecting any data loss on it."

This is a post we found in Microsoft Community, and it seems that over 150 thousand of people have the same question. Will initializing a disk erase data in the same say format does? What's the difference between the two items?

Initialize disk vs format

Typically, both initializing and format would erase data on a hard drive. However, Windows will only ask you to initialize a disk that is brand new and hasn't been used yet. Format is totally different, and it is needed more frequently. For a new hard drive, to put it in daily use on a computer, the process should be Initialize -> Partitioning -> Format

Don't worry, let's distinguish the two concepts more thoroughly. It's easy to decide whether to perform initializing on a new hard drive with zero data on it, however, many of you many have a confusing moment that a used hard disk would require initializing.

And the error message is always about "disk 0 (1 or 2) unknown, not initialized, unallocated". It occurs when this hard drive is initially connected to a computer. So, how are you going to decide whether to proceed to follow the instruction or cancel it? 

How to initialize a disk without formatting?
