A USB drive or removable data storage medium is widely used for storing and transferring data from an iMac, MacBook Pro, and Mac Mini. Its portable nature makes it even more scalable as well as popular among users using different macOS. Even though the ability to transfer a large amount of data among various devices makes it user-friendly, this attribute sometimes creates a few difficulties too. This calls for the need to repair the USB drive to recover the entire data.
When you connect your USB device to different machines, chances for its corruption is higher. In simple words, the more you connect to different systems, the more will be the possibilities of data corruption. Users encounter data loss due to virus or malware that the device may have infected with from the connected system. Alternatively, the corruption issue may occur due to the broken file structure when you eject the device abruptly.
