Summary
To fix 'Disk Unknown Not Initialized' error on an external hard disk, you should initialize the disk at first. Some succeed, but some fail due to a successive error message 'the request could not be performed because of an I/O device error'. This page is to solve this type of [external hard disk not initialized I/O error]. Data recovery is a safe move to the troubleshooting part, and EaseUS hard drive recovery software can handle it well.
Overview: external hard disk not initialized I/O error
What are the reasons that cause hard drive or external hard drive showing unknown not initialized on your PC? Here is a list of known factors:
- Virus attack
- Bad sectors
- Partition Loss
- File system corruption
- Corrupted Master Boot Record (MBR)
Symptoms of the disk not initialized:
- 1. Disk shows as Unknown, Not Initialized with unallocated space.
- 2. Disk shows as Unknown, Not Initialized with no space displayed.
What's I/O error?
An I/O device error, short for Input/Output device error, happens when Windows is not able to perform an input/output action (such as reading or copying data) when it is trying to access a drive or disk. It can occur to many different types of hardware devices or media.
To fix 'Disk Unknown Not Initialized' error on an external hard disk, you should initialize the disk to GPT or MBR at first. Some succeed, but some fail due to a successive error message 'the request could not be performed because of an I/O device error'.
Combining the two consecutive error messages, here you are. When initializing a disk fails and you're caught up in the other unfamiliar I/O error, where is the way out? This page is to solve this type of [external hard disk not initialized I/O error].
Part 1. Recover data from external hard drive unknown not initialized I/O error
You should know that initializing a disk won't damage data, causing data loss problem at all. It's safe to initialize a disk to a normal state when it shows as unknown not initialized.
To initialize a hard disk in Windows Disk Management:
Step 1. Connect the uninitialized external hard drive, HDD or other storage devices to your PC.
Step 2. Press Win + R keys to bring up Run, and type: diskmgmt.msc and hit Enter.
Step 3. Find the uninitialized, unknown external hard drive with I/O device error > Right-click on it and select Initialize Disk.
Step 4. Then set the disk to initialize and set the disk as MBR or GPT.
However, this time is different. You cannot perform the manner of initializing a disk because of I/O error. So, you must turn to other workarounds instead of the most approachable one. Fixes beyond initialization could bring data loss, and it's smart for you to recover data from the inaccessible external hard drive before heading to the troubleshooting in Part 2.

The Request Failed Due to a Fatal Device Hardware Error Scenarios
One of the most common hardware issues happening to Western Digital (WD) and Seagate external hard drive users is the fatal device hardware error, with the exact expression 'X: is not accessible. The request failed due to a fatal device hardware error'. Sometimes, the fatal error is followed by certain error codes, such as '0x800701E3'. Many people have no idea about why their hard drives suddenly stopped and gave such a fatal error message. It's an emergency issue, in fact, because it means your hard drive is dying, and about to put an end to its life.
Figure: the request failed due to a fatal device hardware error.
① WD: the request failed due to a fatal device hardware error

Five Ways to Fix The Fatal Device Hardware Error
As mentioned before, the hard drive cable, bad sectors and hardware issues are responsible for the error, and the corresponding solutions include:
- [1] check the connection
- [2] verify the SMART status
- [3] check and repair bad sectors
- [4] reformat the disk and initialize
- [5] Replace the irreparable disk with a new one, at the same time, keeping data.
Fix 1. Check hard drive connection
A loose connection of a hard drive to the system is likely to throw the error message like this, so try to use your hand pressing a little the USB port.
After checking the connection, a must-try is to connect the external hard drive or portable drive to the motherboard USB port, where supplies more stable power.
At last, go to find a matched but different USB cable. If all attempts come to nothing, you need further troubleshooting behind.
Fix 2. Verify SMART status
Excluding the fault of the hard drive cable and connection, it's time to check the health of the hard drive, to see whether it's damaged or not, and how severely it damaged by checking the drive's SMART attributes. Here, SMART stands for Self-Monitoring, Analysis, and Reporting Technology. You're going to use Windows Management Instrumentation Command-Line (WMIC) as a tool.
This is how to check a hard drive SMART status:
Step 1: Open Windows Command Prompt with the admin privilege (Windows + X keys).
Step 2: In the elevated command prompt, type wmic diskdrive get status and hit Enter.
Step 3: Usually, the command returns four different status, 'OK', 'Bad', 'Unknown', and 'Caution'.
- Ok: Do not worry, try fix 3 and fix 4, you can hopefully restore the hard disk into a normal state.
- Bad, unknown: Quite pesky. You can still face the error with fix 3,4,5. Meanwhile, data recovery is urgent.
- Caution: It suggests the hard drive corruptions at a high level, it's better to take immediate measures to minimize the data loss on the hard disk. Fix 5 is definitely the last chance to deal with an irreparable hard disk.
Fix 3. Check and repair bad sectors
Bad sectors are not as horrible as you think unless they are spreading all over the hard disk. We often use the Windows DiskPart utility to check and repair some file system corruptions and hard disk bad sectors, and it's worth a try when facing a majority of hard drive inaccessibility issues.
This is how to run DiskPart command to fix bad errors:
Step 1: Open Windows Command Prompt as taught.
Step 2: Type chkdsk x: /f /r (x represents the drive letter of the hard drive in trouble)
The syntax for check disk:
- /f fixes system errors
- /f fixes bad sectors
If you don't have any technical know-how and want to minimize data risks, using third-party software could be a better choice. The Command line is suitable for computer professionals since wrong commands can cause severe problems. Therefore, we strongly recommend you try an automatic command line alternative.
EaseUS Tools M is a practical computer fixing tool that is safe and light-weighted. It's a perfect alternative to CHKDSK command. Use this one-click tool to solve your computer issues.
To fix file system error or disk error:
Step 1: DOWNLOAD EaseUS Tools M for Free and install it.
Step 2: Open the software and select the 'File showing' option.
