Hard Drive Showing Unknown, Not Initialized
"Disk (0, 1, 2...), unknown, not initialized and unallocated" is a common hard disk error that upsets us. You can no longer access data when a hard drive becomes uninitialized. Then, how to initialize disk without losing data becomes a problem. You may see a disk showing "Disk Unknown, Not Initialized" in two situations:
- The disk is brand new. You need to initialize the disk to partition it. Afterward, you must format the partition to prepare it for data storage.
- The disk has been used for a period of time and suddenly becomes "Not Initialized".
When adding a brand new disk to your PC, it will show up as "Not Initialized" and won't appear in File Explorer immediately. You need to manually initialize the newly-added hard drive before working with it without worrying about data loss. Here is the detailed information on initializing a new disk from Microsoft.
However, a disk that has been used for a period of time may also become "Not Initialized". This is due to a number of system errors. In such a case, most users have files or folders stored in the disk and are eager to know whether initializing a disk erases its data.
Will initializing a drive erase data? Initializing a disk erases everything on it and prepares it for use by Windows, after which you can format it and then store files on it. That is to say. You will lose your data during the disk initialization and formatting.
But don't panic. If you want to know how to initialize a disk without losing data, you've come to the right place. This article will show you the full steps to initialize your hard drive in a data-secure way. You can first recover data from an uninitialized disk with powerful file recovery software, then initialize your disk safely.
Now you know that disk initialization erases and delete data. Share it on your social media platforms to spread the word.
Based on the information given above, the correct procedures to handle a disk that is not initialized without losing data are:
