I. What are the reasons for the frequent disconnection of the mobile hard disk?

Frequent disconnection of a mobile hard disk can be caused by various factors, including the hard disk’s own failure and other issues that can be addressed to troubleshoot the problem.
external drive failed
●The hard disk is not connected correctly
●The connected data cable is damaged or broken (Please change another cable/USB port and try again)
●Computer USB port damaged

When your external hard drive encounters issues, it raises the risk of data loss. Transfer data from the drive once it can be connected. Use data recovery software if data loss occurs or the drive is inaccessible.
