    External USB drives not being detected by Windows 10 after applying the Anniversary Update

    There is no problem with any of my USB flash drives. They are all recognized. The problem only exists with my Transcend StoreJet 750GB external USB HDD - which ever since installing the Windows 10 Anniversary Update does not show up in File Explorer. To
    be more specific: the disk shows in Device Manager and is correctly listed under Disk Drives. It also shows in Disk Management (no drive letter, no file system, one healthy partition, and 3 unallocated areas). I connected this HDD to a Win 7 machine and it
    was successfully recognized by Windows Explorer.

    Hitachi Ext HDD not recognized in Win 10 1607 (show as 3 unallocated)

    There is a serious bug in the AU with some disks / partitions having a RAW format - that could be your problem? Try that disk on another Pc and check whether the disk is recognised and your data is still there (hopefully).
