The "Disk 1 Unknown Not Initialized" error message typically occurs when a hard drive or storage device is not recognized by the system. This can happen for various reasons, such as a damaged disk, corrupted file system, improper connection, or faulty disk controller. To help you resolve this problem effectively, I recommend you use EaseUS Partition Master Professional.

With the powerful features of this disk management software, you can automatically initialize HDD/SSD and external hard drives on your computer. In addition, this versatile utility also enables users to recover the lost partition.
