Oops, I accidentally deleted partitions on USB

Can you retrieve USB drive lost partitions?

The USB drive is an important device in our daily life as it helps us store important data like photos, videos and music. However, sometimes partitions on the USB drive can be lost or deleted due to improper operations which causes severe data loss. In this case, many USB owners try to find out whether there’s any way to retrieve USB lost partitions? Can they? The answer is yes.

Typically, when a partition is deleted from a USB flash drive, the system removes its assignment for that location on the drive, allowing that section of memory to be overwritten as needed. However, so long as that section of disk remains untouched, there’s still a chance to restore the partition using some sort of recovery software.
