How to Recover USB Partitions?

USB is one of the convenient storage options for files transferring or backing up data securely. However, not many users know that USB drives can be divided into volumes of different capacities. Just like hard drives, by disk partitioning, you can better organize files, have better data management, and have less fragmentation. While it has these advantages, due to various reasons, it sometimes also results in USB partition loss, making it inaccessible. Thankfully, there are many efficient ways to recover USB partitions.

Are you also trying to restore deleted partitions in USB drive? Read along the article to effortlessly recover deleted partition in USB with easy methods in simple steps. We have also included various reasons for the deleted partitions in USB, along with steps to take before proceeding with USB partition table recovery.

Part 1: What Are the Reasons For Deleted Partitions in USB

Data loss can also occur because of deleting or losing a partition from your USB device. Identifying the root cause of this problem can help in applying suitable solutions to restore deleted partitions in USB. Thus, a USB partition can be removed for several reasons, including accidental deletion, software faults, or hardware failure.

Here are some of the common reasons for deleted or lost partitions in USB:

1. Corrupt Sectors: The logical storage unit of every storage drive is known as a sector. Files in a partition are divided into sectors. Each sector on the drive has its read-and-write cycles. However, once these cycles have expired, data cannot be stored in these sectors. If these sectors include system files, their removal may cause the USB partition disappeared.
2. Virus or Malware: When viruses or malware infiltrate a USB device, they aim to destroy or damage the partition. One of the most serious infection side effects on a USB drive might be the device being deleted or rendered inaccessible altogether.
3. Accidentally Deleted UBS Partition: Partitions can often be accidentally erased while conducting file operations. For example, you may mistakenly utilize disk management tools or format a USB device.
4. Software Bugs: The deletion or loss of the USB partition can occasionally result due to a problem or error in the operating system or disk management software. Following the partitioning process, a software error or malfunction could lead to an unexpected partition elimination.
5. Improper Ejection: Another typical cause is abruptly disconnecting a USB hard drive from your computer while reading or writing. It can result in data damage or a corrupted partition table. This may cause the partition to be erased or become unavailable.
6. Reformatted Drive: When a USB drive is formatted or reformatted, all the data and partitions are wiped. As a result, before performing drive re-partitioning and reformatting, it is important to ensure that everything on it has been fully backed up.
7. Physical Damage: Deletion or loss of partition can also occur if the USB drive is physically damaged, for example, a broken connector or a malfunctioning controller.

Part 2: Steps to Take Before Recover Deleted Partition in USB

If your USB partition is lost or corrupted, you should fix it right away. Typically, drive corruption happens on the partition table, suggesting the missing USB partition is still available. However, you have to proceed with caution as you could risk causing permanent data loss.

Following are the steps to avoid when repairing a USB partition:

• Transferring Files: Avoid copying or moving files on a USB drive, as it can destroy your data. Since your lost USB data is still present, adding new entries will overwrite them. In addition to the possibility of overwriting lost data, the file system on your corrupt USB device is unstable. Moving files on your USB drive may result in interrupted transfers and additional corruption.
• Formatting USB: A deleted or lost USB partition is not completely lost, but it is only inaccessible. If you format your USB drive, you risk permanently losing your data. If you run a Quick Format, you might be able to restore your data. A Full Format, on the other hand, deletes all data on your USB device permanently. As a result, while formatting can help you fix file system damage on your USB drive, it should only be used as a last resort.
• Re-partitioning USB: While partitioning divides your USB drive into many parts, re-partitioning creates, manages, and deletes partitions. If you modify the structure of your USB drive after a partition has been erased, you risk permanently losing the data on that partition. However, partitioning does not erase data because it uses unallocated space. However, in the case of corrupted USB partitions, it can create more corruption and render your data unrecoverable. As a result, you should avoid it before fixing your USB drive.
