How to Recover Lost Data from Disabled USB Device on Mac

A USB drive saves data in a smaller drive like a hard disk. When this data is needed later, you can plug in the device and get the data. However, many reasons could make your USB device inoperable, including data corruption, if the drive is unmounted incorrectly from the port, etc. In addition, invalid data in the Master Boot Record (MBR) or Partition Boot Record (PBR) or directory layout on the USB device can also cause data corruption. This makes you lose data; luckily, you can get back the lost data from a disabled USB device using a data recovery tool.

Note: If you have lost or deleted files, avoid performing any operation on the USB. The more actions you perform after deleting files, the chances of overwriting files increase, and recovery chances decrease.
