I used AOMEI Partition Assistant to clone my C Drive (SSD) to a bigger SSD. Boots fine but my other 3 HDD's aren't recognized. Not in File Explorer nor Disk Management. I'm running Win 10 Pro Ver. 20H2 (OS Build 19042.928). What can I do?

If it doesn't work exactly as previous, the clone operation was not 'successful'.

What specific drives are involved here? Make/model.
What specific motherboard?

OK, just verifying that this wasn't an M.2 drive, which would have brought its own complications.

Redo the clone.
Have ONLY the current C drive and the new PNY connected.

Just like this...
-----------------------------
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

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.

Followed your instructions. Boots fine but other drives still not showing up in Computer management. They do show up after I pop the old drive back in. Anything else I can try?
