My Exos Hard Disk Won't Format at All, What Should I Do

I get a brand new Seagate Exos 18TB external hard drive, but it won't format at all. I tried many tools but none of them work. I'll appreciate it if anyone can tell me any solutions for this error.

Your problem is "Exos hard drive won't format." This issue can be caused by various reasons, including viruses, outdated hardware drivers, missing or corrupted system files, etc.

Based on the reasons, you can follow the guides below to fix this error:

Guide 1. Remove Viruses via Windows Defender

Follow the steps here, and you can remove the virus on your hard drive:

Step 1. Go to "Settings" > "Update & Security" > "Windows Security."

Step 2. Choose the Virus & Threat Protection section.

Step 3. In the Threat History section, click Scan Now to scan your computer for viruses.

Guide 2. Run CHKDSK Command

If you cannot format your hard drive and the device is not RAW, you can run CHKDSK to repair possible disk errors. Here is how:

Step 1. Press Windows, and then type the command: cmd.

Step 2. Right-click on the search result, "Command Prompt," and choose "Run as Administrator."

Step 3. In the CMD window, type chkdsk E: /f and press "Enter." (Replace the letter "E" with the letter of your Exos hard drive.)

After the process, you can use EaseUS Partition Master to format your hard drive again, and this tool can help you set the best allocation unit size for your hard drive.
