Factors Cause Loss of Partitions on SD card/ USB drives

Partitions on removable media are more likely to get deleted or lost than those on hard drives. This is because SD cards, USB, or pen drives are offhandedly used with multiple devices.

Let’s look at the below factors that caused the loss of partitions on SD cards and USB drives.

  1. Abrupt removal of SD card/USB from laptop or camera.
  2. Accidentally formatted.
  3. Infecting a virus while transferring files between devices can damage the partition, making it inaccessible.
  4. Excessive use of removable media in different devices can create bad sectors which can lead to partition corruption.
  5. Improper use can also damage the file system and delete partitions on the memory card.
  6. Sudden power loss, system shutdown, or operating system crash while accessing removable media can corrupt and render the partition inaccessible.

Restore Deleted Partitions on SD Card/ USB Drive

To recover a lost SD card partition on Windows, first, go to your system’s Disk Management. If you see unallocated space for removable media, fix it.

Solution 1: Assign a drive letter to the SD card/USB drive

Although you think the partition on the SD card/USB has been deleted, the problem could be something else. Removable media might not show up in File Explorer because a drive letter isn’t assigned to it, or because another drive uses the same letter.
