Question How to format SSD to factory defaults?

Jun 30, 2021
Long story short: I got a 512GB SSD to replace my 256. Decided to clone my drive using Macrium Reflect but it also cloned the partition size, so now about half the drive's space is being wasted (gray area far right on the screenshot).

How do I fix this? Is extending the volume the only way?

Any and all help appreciated.

P.S. I would much rather take back the disk to factory defaults (no partition) and redo the cloning if that is somehow possible. Right now I'm stuck with a 211GB partition on E:, which is exactly what I do not want. I want E: to be a ~500GB partition. Please help.

Macrium has a function to manipulate the size of the resulting partitions, before you click the go button.

Redo the clone, thusly:

Specific steps for a successful clone operation:
Verify the actual used space on the current drive is significantly below the size of the new SSD
Download and install Macrium Reflect (or Samsung Data Migration, if a Samsung SSD)
If you are cloning from a SATA drive to PCIe/NVMe, install the relevant driver for this new NVMe/PCIe drive.
Power off
Disconnect ALL drives except the current C and the new SSD
Power up
Run the Macrium Reflect (or Samsung Data Migration)
Select ALL the partitions on the existing C drive

This part right here is what you need to pay attention to....
If you are going from a smaller drive to a larger, by default, the target partition size will be the same as the Source. You probably don't want that
You can manipulate the size of the partitions on the target (larger)drive
Click on "Cloned Partition Properties", and you can specifiy the resulting partition size, to even include the whole thing

Click the 'Clone' button
Wait until it is done
When it finishes, power off
Disconnect ALL drives except for the new SSD
This is to allow the system to try to boot from ONLY the SSD
Swap the SATA cables around so that the new drive is connected to the same SATA port as the old drive
Power up, and verify the BIOS boot order
If good, continue the power up

It should boot from the new drive, just like the old drive.
Maybe reboot a time or two, just to make sure.

If it works, and it should, all is good.

Later, reconnect the old drive and wipe all partitions on it.
This will probably require the commandline diskpart function, and the clean command.

Ask questions if anything is unclear.
