How to Recover and Repair USB Drive Partition

Summary: USB drive partitions may be lost or corrupt for many reasons, leaving you worried about your data. However, you can retrieve your data and repair the USB partition using the methods shared in this blog. For quick action, you can use a dedicated USB partition recovery tool.

Disk Partitioning is a logical division of storage media drives, such as HDDs, SSDs, etc. It can be used for partitioning internal and external storage drives, such as HDDs, SSDs, etc. Similarly, you can also partition the USB drives in volumes of different sizes for the purpose of segregating files, improving data management, and reducing fragmentation.

However, the partition may get deleted or become inaccessible if your USB drive experiences failure due to corruption, virus infection, or human errors (accidental drive formatting or deletion). All such scenarios put your device and its data at risk. Don’t get anxious yet. Here, in this blog, we have listed some of the best methods to perform USB partition recovery.

What Causes a Lost Partition on USB Drive?

There could be several reasons behind the lost USB partition. Here are a few primary ones:

If you accidentally formatted your USB drive partition, all the partition data will be deleted.

Malware or virus infection can make your USB drive partitions inaccessible or hidden, leading to data loss.

If the partition table, containing information about hard drive partitions’ beginning and endpoints, file system, and so on, runs into any logical error, it may lead to USB partition loss.  

Quick Update: Earlier, ‘Unsafe removal’ of the USB drive without ejecting it used to be one of the main reasons behind USB corruption, partition loss, and other failures. However, it’s no longer the scene. Microsoft has confirmed that now users don’t have to worry while removing USB without safely ejecting it from the system.

Below, we have shared some methods to help you solve the ‘USB partition lost’ problem. You can follow the methods to recover the lost USB partition’s data and then proceed to repair the drive.

How to Recover USB Partition without Losing Data?

Here, we have mentioned manual and automated methods to perform USB partition recovery. Follow the instructions carefully to retrieve data from a USB partition while avoiding any damage.

#1 Run Attrib Command

Virus or malware infection can change file attributes in a USB storage media. By changing attributes, it hides the data and creates executable shortcuts to your hidden files and folders. When you click a shortcut, it spreads the virus on the system. Thus, if you see any shortcuts on your USB drive partition, use the ‘ATTRIB’ command to restore files hidden by virus or malware infection and then run an antivirus scan to quarantine the infection. Follow these steps:

#2 Use Data Recovery Software

If the above method doesn’t work, you can take the help of data recovery software, such as Stellar Data Recovery Professional. This DIY data recovery software is quite easy-to-use yet powerful enough to retrieve lost data due to deletion, drive formatting, corruption, etc. The software efficiently scans the drive and looks out for lost, missing, or deleted data. The software can even find the missing drive partitions and their data. To recover lost data from the USB partition, follow the given steps:

Can a corrupted USB partition be repaired?

After recovering data, if the USB drive partition is logically corrupted or damaged, you can repair it with some of the proven workarounds shared below.

Change the Drive Letter

Suppose your USB device shares the letter similar to the system’s existing partition. In that case, it may not be accessible or detectable by the OS or File Explorer. In such a case, you may try changing the drive letter from Disk Management and fix the issue.

Run CHKDSK Command

A USB drive partition may turn RAW due to improper use, malware infection, and sudden power failure. This can cause data loss as the drive becomes inaccessible. However, you can run the CHKDSK scan to fix a RAW drive partition and repair the damaged file system. Follow these steps:

After the scan is finished, detach and then reconnect the USB drive to access the drive. If the drive is still RAW, it may be severely corrupted or physically damaged. Either take it to the device manufacturer or replace it with a new one.
