External hard drives are one of the most frequently used data storage devices. However, when we enjoy the convenience it brings, we may also encounter various related issues, like hard drive not recognized, external hard drive not showing files, and, the case we focus on here, external hard drive format error. There are two types of format errors: the external hard drive asking to format, or the external hard drive not formatting. Specify your situation and follow the corresponding solutions to cope with the issue.

  1. Mac’s running OSX can read NTFS drives as standard but cannot write to them. If you want to write to an NTFS drive with a Mac then NTFS for Mac from Tuxera is a good option. You can also move files to and from Windows and Mac machines across your network or use a NAS drive as an intermediate storage device.
  2. To use HFSExplorer, connect your Mac-formatted drive to your Windows PC and launch HFSExplorer. Click the “File” menu and select “Load File System From Device.”. It will automatically locate the connected drive, and you can load it. You’ll see the contents of the HFS+ drive in the graphical window.

Make your hard disk or USB flash drive compatible to both Mac and Windows PCs using this easy step by step guide. The irony is that, by default, Windows and Mac use different file systems. While Windows uses NTFS file system, Mac hard drives are formatted with HFS file. Click Erase to finish. Your exFAT-formatted drive or partition can now be used for both Windows and Mac. Note that using a drive frequently between Windows and Mac could increase the chances. Here is the solution to format your hard drive, which is refusing to be formatted: Open the Start menu and enter diskmgmt.msc in the search bar to access Disk Management. Click on Run as administrator. Locate the faulty disk, and Right-click on it to open the drop-down menu. Click on Format from the menu.

Part 1. External Hard Drive Not Formatted

'Recently, I ran into a problem while accessing my Seagate 160 GB external hard drive. Whenever I tried to open it, Windows showed me that my hard drive was not formatted and asked me to format it. It's really annoying! How can I fix this problem without losing my data?'

Causes

Generally, when Windows says your hard drive is not formatted, you will see your external hard drive shown as RAW under File Explorer or Disk Management.That's because:

  • The file system of your storage device is corrupted due to a power outage, sudden ejection, virus attack...
  • The file recognized by the operating system of your computer.

External Hard Drive Mac To Windows

Notice:
The file system of a hard disk or partition controls how data is stored and retrieved. It's the bridge between data saved on your device and the OS.

File system errors prevent you from accessing your external hard drive. That's why Windows asks you to format the device since formatting will assign a new file system to the external hard drive. With the file system, the hard drive can be used for data storage again. Generally speaking, you need to format the disk before you can use it.

Solution

Some say the external hard drive not formatted error could be fixed by running CHKDSK. In fact, when you attempt to run CHKDSK on a storage medium with file system errors, it will fail to repair the disk, and CHKDSK will reports RAW. Therefore, the most straightforward way is to format the external hard drive directly. If you don't want to lose the files on your device, perform data recovery first and then format the hard disk.

Procedure 1. Recover Data from the RAW External Hard Drive

When the 'You need to format the disk in drive before you can use it' prompt pops up, you can actually recover the inaccessible files using hard drive recovery software like EaseUS Data Recovery Wizard. It's capable of recover data after deletion, format, drive becoming RAW, and other data loss situations.

Download the software now and follow the detailed steps to recover data from your external hard drive beforehand.

Note: To guarantee a high data recovery chance, install EaseUS data recovery software on another disk instead of the formatted disk.

Step 1. Choose the formatted hard drive

Choose the hard drive partition which you've accidentally formatted and click 'Scan'.

Step 2. Select wanted files

After the scanning process, you can click 'Filter' to filter a specific file type to quickly find wanted files. Then use 'Other Lost Files' or 'Files Lost Original Name', 'Tags', etc. in the left pane to locate your files.

Step 3. Recover files to a secure location

Select the data that you wish to recover and click 'Recover'. Choose a new location to store the files and click 'OK'.

Procedure 2. Format the External Hard Drive

After saving your external hard drive data to a safe place, you can execute the format. The easiest way to get things done is to format an external hard drive under File Explorer. Here is the step-by-step guide.

Step 1. Open 'This PC' (in Windows 10) and go to 'Devices and drives'.

Step 2. Right-click your external hard drive and choose 'Format'.

Step 3. Choose the file system and click 'Start'.

Step 4. In the warning prompt, click 'OK' to start formatting your hard disk.

If your external hard drive doesn't format, move on to the next part.

Part 2. External Hard Drive Won't Format - The Format Did Not Complete Successfully

'I have an LG external hard drive which I unplugged one day without doing the safe eject. Now it won't work. The computer recognizes its existence on the F drive, and Disk Management says the status is healthy (primary partition). But it will not format. Under the File system, the drive is described as RAW. I do not need to recover the data but I got it only six months ago and hate to have to throw it away and buy a new one. Any help would be much appreciated.' — From How-To Geek Forum

Driver

When you try to format an internal or external hard drive, you may receive one of the three error prompts that indicate a format failure:

  • 'The format did not complete successfully.'
  • 'The request could not be performed because of an I/O device error.'
  • 'Drive is not accessible. The parameter is incorrect.'
Notice:
If you are in one of the last two situations, go to the related article to get the solutions. The fixes provided in this article mainly focus on the first situation.

Causes

Unlike the external hard drive saying it needs to be formatted, external hard drive not formatting could result in various reasons, including:

  • Your storage medium is infected by a virus
  • The hardware driver is outdated
  • System file (DLL, SYS, EXE) is missing or damaged
  • your hard disk is damaged

Solutions

Based on the possible causes, there are six workable solutions to the problem 'External hard drive not formatting':

Method 1. Remove the Virus

You can run the anti-virus software installed on your computer or Windows Defender.

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

Step 2. Click 'Virus & threat protection'.

Step 3. In the 'Threat history' section, click 'Scan now' to scan for viruses on your computer.

Method 2. Update Hardware Driver

Updating the hardware driver can easily fix the hard drive format error caused by an outdated device driver. You can do it under Disk Management.

Step 1. Connect the external hard drive to PC, right-click on 'This PC' (in Windows 10), and choose 'Properties'.

Step 2. Click 'Device Manager' then expand 'Disk drives'. Find and right-click the problematic USB drive and select 'Update driver'

Step 3. Click 'automatically search for driver software online'.

Step 4. Wait for the driver to be updated, then reboot your computer. Afterward, reformat your external hard drive to have a try.

Method 3. Run System File Checker Tool

The Windows built-in System File Checker tool can repair missing or corrupted system files, including the DLL, SYS, or EXE files that cause your external hard drive won't format. Here are the simple steps to run the tool:

Step 1. Click 'Start' and type cmd.

Step 2. Right-click 'Command Prompt' and choose 'Run as administrator'.

Step 3. Enter the following command lines in order. (The DISM command is used to make a Windows image to protect your data.)

Device

DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow

Method 4. Run CHKDSK

If you won't be able to format your external hard drive and the device is not RAW, you can run CHKDSK to repair possible disk errors on it.

Warning
Running chkdsk can hopefully fix the hard drive issues, however, it can also result in total data loss. So, perform data recovery in advance, and then continue with the CMD method.

Step 1. Press the 'Windows' key and type cmd.

Step 2. Right-click 'Comand Prompt' and choose 'Run as administrator'.

Step 3. In the CMD window, type chkdsk G: /f and hit 'Enter'. (Replace 'G' with the drive letter of your external storage device.)

Step 4. Then Windows will start checking and repairing disk errors and damaged files. Wait for the process to finish.

Method 5. Format your External Hard Drive via DiskPart or Third-Party Software

As mentioned, there is more than one way to format a hard drive. If you failed under File Management, you can retry using DiskPart or a third-party hard drive format tool. To use DiskPart:

Step 1. Press 'Windows + R' and enter diskpart. Click 'Yes' in the prompt to run diskpart.exe.

Step 2. Then enter the command lines below in order:

list volume
select volume X ('X' means the volume number of the RAW drive)
format fs=ntfs quick (or format fs=fat32 quick)
exit

Method 6. Delete the Partition and Recreate a New Volume

If the methods above don't work, there is one more tip worth trying, which is to delete the partition and then create a new volume.

Step 1. Right-click 'This PC' and choose 'Manage'.

Step 2. Right-click the problematic disk or partition and choose 'Delete Volume'. In the 'Delete simple volume' prompt, select 'Yes' to confirm the deletion.

Step 3. Afterward, the deleted partition will show up as unallocated space. Right-click the unallocated space and choose 'New Simple Volume...'

Step 4. In New Simple Volume Wizard, click 'Next' to continue.
