    Cloning to SSD then swapping drive letters


    @SamHobbs
    What you want done is very simple and can be done in short period of time. Here's my suggestion:
    There's 2 modes that Windows can be installed: UEFI and the old legacy MBR. Open Disk Management, look at the disk where your C drive is, if there's a
    1. EFI System Partition, your Windows was installed using UEFI.
    2. System Reserved partition, your Windows was installed using MBR
    Next, Connect your SSD to an available Sata port (no need to format or do anything). Download: Macrium Reflect Free . Install and run. Follow the steps below:
    1. From Macrium, click on image this disk under your C drive and save it to either an Internal or External Drive. This will create a single backup image of the whole disk containing your C drive.
    2. Again, from Macrium, click on Restore tab and select the image created from step 1, Select your SSD as the destination drive, click Next->Finish
    3. Exit Macrium. If your Windows was installed using MBR, Open disk management and make sure the SSD is marked "Active" else go to next step.
    4. Shutdown your PC. Disconnect the HD containing Windows C drive then connect your SSD to it.
    5. Reboot. Your PC should boot and the Windows should have C as the drive letter.

    NOTE: The procedure above is to backup your Windows to an image file then copy it back to the SSD. This ensures proper cluster size aligment for the SSD. In addition, Macrium also perform Trimming for the SSD. This is more preferable than cloning.

    Windows 10 1903 Restart zaps SSD drive letter

    help. USB drive isn't assigned a drive letter.

    Any usb flash drive I plug into my computer isn't assigned a drive letter. The physical drive shows in the "safely remove hardware" but it doesnt show up in disk management. I have tried to populate the volume thru the safely remove hardware properties window and it does pop up in the list but it doesn't stay there. This isn't a format or assign a letter problem. It's more complicated then that. Maybe one of the services needed for usb drive management was disabled? Suggestions needed. btw external usb harddrives work fine.
