    In most cases, when you say that the external hard drive is not recognized, you mean the external hard drive can't be detected by My Computer. Under the circumstances, you can firstly go to Disk Management to check whether it can be recognized.

    Scenario 1. If your external hard drive can be recognized by Disk Management but is unrecognized by My Computer, it may lose drive letter, become RAW file system, or suffer from partition loss.

    • > When there is no drive letter of external hard drive in Disk Management, you can right click the unrecognized external hard drive to change drive letter and paths. Just assign a new drive letter to the external hard drive, and then it can be recognized by My Computer.
    • > When the external hard drive shows as RAW file system or no file system in Disk Management, you can recover lost data from RAW external hard drive with iBoysoft Data Recovery.
    • > When the external hard drive shows as unallocated space in Disk Management, you can use iBoysoft Data Recovery to find lost partition and then recover lost data from it.
