+## Linux
+
+### Identify the USB Drive
+
+First, you need to identify the drive you want to reformat. You can list all the storage devices in your computer with the following command:
+
+\`\`\`bash
+lsblk
+\`\`\`
+
+This will give you a list of devices along with their mount points. Your USB drive will usually be something like `/dev/sdb` or `/dev/sdc`.
+
+### Unmount the USB Drive
+
+Before reformatting, you should unmount the drive. This can be done with the following command:
+
+\`\`\`bash
+sudo umount /dev/sdX
+\`\`\`
+
+### Format the USB Drive
+
+Now you can start the process of reformatting. You can use `fdisk` to manage the partitions on your USB drive. Use the following command to start `fdisk` for your drive:
+
+\`\`\`bash
+sudo fdisk /dev/sdX
+\`\`\`
+
+Once you're in the `fdisk` utility, you can use the following commands:
+
+- `p` - Display the partition table to confirm you're working with the correct drive.
+- `d` - Delete a partition. If there are multiple partitions, it will ask you which one you want to delete. Repeat this step until all partitions are deleted.
+- `n` - Create a new partition. Follow the prompts to accept the defaults.
+- `t` - Change the partition type. If asked for a code, use `b` for FAT32 or `83` for Linux.
+- `w` - Write changes and exit.
+
+### Create a File System
+
+Now that you have a new partition, you can format it with a file system. If you want a FAT32 file system, you can use the following command:
+
+\`\`\`bash
+sudo mkfs.vfat /dev/sdX1
+\`\`\`
+
+Or if you want an ext4 file system, use this command instead:
+
+\`\`\`bash
+sudo mkfs.ext4 /dev/sdX1
+\`\`\`
+
+### Mount the USB Drive
+
+Now you can mount the drive again:
+
+\`\`\`bash
+sudo mount /dev/sdX1 /mnt
+\`\`\`
+
+Now your USB drive is reformatted and ready to use!
+
+> **IMPORTANT:** Be very careful when using these commands, as choosing the wrong drive can result in data loss. Always double-check the drive name (`/dev/sdX`) before running these commands.
+
+## Windows diskpart
+
+1. Open Windows PowerShell as an administrator.
+  
+  \`\`\`powershell
+  diskpart
+  \`\`\`
+
+2. List all the connected storage devices.
+
+  \`\`\`powershell
+  list disk
+  \`\`\`
+
+3. Identify your USB drive by its size and replace X with its disk number.
+
+  \`\`\`powershell
+  select disk X
+  \`\`\`
+
+4. Delete all data and partitions on the drive.
+
+  \`\`\`powershell
+  clean
+  \`\`\`
+
+5. Create a new primary partition.
+
+  \`\`\`powershell
+  create partition primary
+  \`\`\`
+
+6. Select the newly created partition.
+
+  \`\`\`powershell
+  select partition 1
+  \`\`\`
+
+7. Format the partition to FAT32 or NTFS (replace "fs=fat32" with "fs=ntfs" if you want NTFS file system).
+
+  \`\`\`powershell
+  format fs=fat32 quick
+  \`\`\`
+
+8. Assign a drive letter to the partition (replace "Y" with your desired drive letter).
+
+  \`\`\`powershell
+  assign letter=Y
+  \`\`\`
+
+9. Exit DiskPart.
+
+  \`\`\`powershell
+  exit
+  \`\`\`
+
+> This guide will completely erase all the data on your USB drive and prepare it for fresh use. Be sure to replace X with your disk number and Y with the desired letter for your drive.
