My pen drive not formatting

“My friend gave me a 32GB pen drive. When I tried to format it to NTFS in File Explore, I just got the message Windows was unable to complete the format. I entered Disk Management to format the USB drive but still failed. Is my pen drive corrupted? How can I format it to NTFS successfully?”

Pen Drive not Formatting

Format pen drive using CMD

If you are in the situation mentioned above, you may find that your pen drive becomes RAW in Disk Management. That is to say, the file system of the pen drive partition is corrupted or damaged.

RAW Pen Drive

In such a condition, you can format your pen drive, SD card, or external hard drive using CMD. See the detailed steps below (Take formatting pen drive in Windows 7 as an example)

Note: Formatting pen drive will remove all data on it, thus you can make a backup at first if there are any necessary files on it.

1. In the Search box, type “CMD”, right-click Command Prompt among pop-up results, and select Run as administrator to open Command Prompt.

2. In the appearing window, type diskpart and hit Enter.

3. Run the following commands:

▪ list disk (all disks connected to your computer will be listed)
▪ select disk n (“n” is the number of your pen drive)
▪ clean
▪ create partition primary
▪ select partition 1
▪ format fs=ntfs (you can replace ntfs with exfat or fat32 if you want )
▪ assign drive letter f (“f” can be replaced if you want)

Then, you can type “exit” and hit Enter to close this window.

If you receive the message that Diskaprt has encountered an error: the media is write-protected while running “clean” command, you can run these commands: list disk> select disk n>attributes disk clear readonly, to disable write protection from pen drive at first.

Format pen drive using a GUI format tool

If you are not familiar with Command Prompt, it is not advised to format pen drive using CMD as the operations mentioned above are irreversible and you may format the wrong disk, which will cause data loss. If you want to format the partition larger than 32GB, the Diskpart utility can’t help you. At this point, this excellent and powerful free format tool – AOMEI Partition Assistant Standard will be your best choice.
