Replaced Dell Latitude 15 3590 with HDD -equipped notebook to 1TB SSD, speeding up 4 times faster.
In this replacement, Windows Update was implemented before the work, but in the process, the C drive area was encrypted by BitLocker, so it is performed in advance.
Whether the partition is encrypted can be confirmed from the "Bitlocker Drive encryption" in the Windows control panel.If it is encrypted, unlock the data before cloning.Data clones cannot be performed with encrypted.
As in this case, when a large update of Windows 10 is applied, "Bitlocker is not enabled in the display on Windows, but the data is encrypted".Alternatively, you can enable BitLocker on the OS and then disable it to unlock the encryption.
Once you release BitLocker, you can complete the clone normally with Samsung Data Migration.
