It really doesn't seem to make much (if any!) sense that you're not able to clone the 88 GB of data contents of the 1 TB source drive to your 480 GB destination drive. I'm of course aware of your report of the failure of both the EaseUS Todo & Macrium Reflect programs to successfully carry out the disk-cloning operation with both programs apparently returning a "insufficient disk space" error msg. (presumably referring to the destination drive). On the face of it there doesn't seem to be a valid reason for this failure.
Your system appears to meet the basic criteria for a successful disk-cloning operation, in that...
1. Your present 1 TB boot drive boots to its OS and thereafter functions without problems.
2. Your SSD (the destination drive for the cloned contents of the boot drive) is non-defective.
(BTW, Kingston has a SSD Toolbox available - see
https://www.kingston.com/us/support/technical/kingston-ssd-toolbox
Download the program and just as a precaution check out your Kingston SSD, OK?)
3. The disk-space capacity of your SSD is sufficient to contain the TOTAL contents of the boot drive.
All the above criteria are met, right?
Both the programs you've used are considered quite reliable so when a disk-cloning operation fails when using either of those programs the cause is nearly always either the above criteria are not met or user-error in undertaking the operation. So it's difficult, if not impossible, for me to account for this failure of the disk-cloning operation in your situation.
Be that as it may...
If you're so inclined to give this d-c operation another "go" I would like you to try the d-c program we nearly always employ (primarily for comprehensive backup purposes). I'll provide you with specific detailed instructions for using the program.
The program is Casper and you can download a 30-day trial version from...
https://www.fssdev.com/products/casper/trial/
(The commercial version costs $49.99. The trial version is slightly crippled as compared with the commercial version, but should pose no use problem with your drive's configuration.)
1. After installing the program and before undertaking the disk-cloning operation close all open programs. (Generally you need not disable your anti-virus program). Ensure your destination drive - the proposed recipient of the clone, your SSD - is properly connected in the system.
2. The opening screen of the program will highlight "Create a Bootable Backup". Click on "Add drive" and a listing of the appropriate destination drive(s) will appear, e.g., your 480 GB SSD.
3. Click on the destination (SSD) drive's listing and then the "Back up now" button.
4. Casper will run in the background and alert you when the disk-cloning operation is completed. (You can view the actual progress chart by clicking on the Casper icon in the Notification Area on the Taskbar.)
5. Following the (hopefully!) successful disk-cloning operation disconnect the source HDD from the system and boot SOLELY to the connected destination drive, your SSD. As a general proposition it's a good idea (whenever practicable) for the newly-cloned drive to be connected to the motherboard's first SATA data connector, usually designated SATA 0 or SATA 1 although this is not mandatory
.
Also, check the system's BIOS/UEFI upon the initial boot to the newly-cloned drive to ensure that drive is now first in boot priority order.
6. Work with the newly-cloned SSD for a while to determine it boots & properly functions before reinstalling the HDD which will then serve as a secondary drive in your system.
7. Ordinarily Casper will utilize the entire disk-space of the destination drive to contain the data contents from the source drive. In some cases the program will create a partition on the destination drive (your SSD) only to the extent of the total data cloned. If that does happen, you can use Disk Management to simply extend the partition to encompass the total disk-space available on the SSD; a simple operation.
Give it a try and let us know how it goes.
