USB flash drives are convenient and portable storage devices that we rely on for storing and transferring our important files. However, sometimes we can accidentally make a mistake and use the wrong command, such as dd, when formatting or working with our USB drive.
This can result in the USB drive becoming unresponsive or inaccessible. In this blog post, we will guide you through the steps to recover the functionality of your USB flash drive after using dd.
Step 1: Stop Using the Drive
The first and most important step is to stop using the USB flash drive immediately after realizing the mistake. Continuing to use the drive can potentially overwrite the data and make it more difficult to recover. Remove the USB drive from your computer and set it aside for the recovery process.
Step 2: Assess the Damage
Before proceeding with the recovery process, it is essential to assess the damage caused by using dd. Connect the USB drive to your computer and check if it is recognized by the operating system. If the drive is not detected or shows up as unallocated space, it indicates that the partition table has been overwritten.
Step 3: Use TestDisk
To recover the functionality of your USB flash drive, we will be using a powerful open-source data recovery tool called TestDisk. TestDisk is available for Windows, macOS, and Linux and can help you recover lost partitions and repair damaged file systems.
Step 4: Download and Install TestDisk
Start by downloading TestDisk from the official website and install it on your computer. Once the installation is complete, launch TestDisk and select the USB flash drive from the list of available devices.
Step 5: Analyze and Repair the USB Flash Drive
TestDisk will analyze the USB flash drive and display the current partition structure. Select the option to ‘Proceed’ and let TestDisk scan for lost partitions. Once the scan is complete, TestDisk will present a list of partitions that it has found.
Step 6: Write the Partition Table
After scanning for lost partitions, TestDisk will allow you to write the partition table to the USB flash drive. Confirm the changes and let TestDisk rewrite the partition table. This process will restore the functionality of the USB drive and make it accessible again.
Step 7: Format the USB Flash Drive
Once the partition table has been successfully restored, you can format the USB flash drive using the operating system’s built-in formatting tool or a third-party formatting utility. This will erase all the data on the drive, so make sure you have a backup of any important files.
