Initialize Disk - You must initialize a disk before Logical Disk Manager can access it
Are you one of the hard drive owners who receive such a Windows prompt that warns you to initalize your disk? Do you feel a sense of anxiety when you're faced with a choice?
Being different from another similar error titled with "disk unknown not initialized", the suggested solution towards the "You must initialize a disk" issue is given along with the error message. It means that you must use either MBR or GPT as the partition style for the selected disk by initializing it.
However, many people still feel puzzled as they don't know whether the solution can be applied on both new and used hard disk. Continue reading, and you will figure out why would Windows recommend to you do so:
Identify your disk - a new or a used disk
1. Brand new hard disk: The hard drive is a completely new, unformatted hard drive without anything on it so far.
2. Used hard drive: It's a hard drive that is already in use. It contains plenty of data files on it.
The differences between initializing a new disk and a used drive
First, for a brand new disk: The case of "You must initialize a disk before..." implies that Windows cannot access the drive you have connected to it. Initializing the disk will rebuild the MBR on the disk so to enable Windows OS access to the target disk. By doing so, you can create partitions on the disk and use the disk to save data.
Second, for the disk that has already been in use: Due to disk driver or other issues, the disk becomes undetectable by Windows and you have to reinitialize the disk. However, initializing will result in a complete data loss on it. In this case, data recovery should be executed immediately once you initialize the disk.
How to Fix "You must initialize a disk" Error without Losing Data
The provided fixes are also applicable to remove the same error from your external hard drive, USB, pen drive, SSD, etc., devices.
You should know that the "You must initialize a disk" issue may also happen to an SSD, external hard dirve, USB flash drive, etc., devices. Continue reading and choose the right fix to get rid of this issue from your hard drive without losing data.
Sometimes, if your disk is not correctly inserted or connected to your computer, Windows OS won't be able to load the device and you may even receive the error message. A quick fix to this issue is to unplug the disk from your computer, check the SATA and power cable, and reconnect it to your computer correctly.
If this doesn't work, the connection of your drive is all right, try any fix below to make your drive work again.

Provided that your external HDD, SSD, or USB is not a faulty one or completely dead (there is no way but replace it), initializing should be the quickest and easiest way to solve the pending problem. Then, you can download Qiling hard drive recovery software to recover data from a hard drive after initializing. That's the other way to protect you from losing everything on it.
First. Initialize the disk - HDD/SSD/USB

In fact, we've kept studying many disk initializing error and related issues. We also connected 3 top concerned questions from Google and find the best answer to these questions.
If you are interested, check the answer here now:
1. Will initialize a disk erase data?
Will initializing disk erase data on it? The answer is both "Yes" and "No". Solely initializing a disk won't erase its data. But in order to use the disk, you need to further partition and format the disk, which will cause data loss. Thus, if you don't want to lose files existing on your hard drive, using data recovery software is necessary.
For more details, you should refer to How to recover data from a hard drive after initializing for help.
2. How do I initialize my new SSD?
To initialize your new SSD by using Disk Management as recommended in Fix 1. Besides this, you can also apply another two methods to initialize your SSD:
1). Using CMD initializing disk command; 2). Using Qiling Partition Master with its Initialize Disk feature.
Both two methods are practical and efficient in executing this task. For more details, see also: How to Initialize an HDD/SSD.
3. Should I initialize MBR or GPT?
To answer the question of How should you initialize disk to MBR or GPT, you should first understand your initial intent.
1). To use the disk as new system disk:
To do so, you should open Disk Management > Right-click your system disk and select "Properties" > Check the disk partition style. If it's MBR, you should initialize the disk to MBR. If it's GPT, initialize to GPT.
2). To use the disk as a data drive:
If you need to create more than 4 primary partitions and your disk is more than 2TB, initialize it to GPT. If not, initialize it to MBR.
