Hyozans :
Sorry, I guess my link wasn't very obvious. This is the cable I was using when attempting to clone via USB:
StarTech.com USB 3.0 to 2.5" SATA III Hard Drive Adapter Cable w/ UASP - SATA to USB 3.0 Converter for SSD/HDD
Anyway, so I connected the drive via SATA and it now shows up in the BIOS and in the Data Migration and Magician tools (it does not show up in Windows Explorer though). I went to migrate the data.. but it only shows that the C: drive will be transferred. My setup is that I have a 128 SSD already (which has my OS and some programs) and an HDD which has many of my files and some programs. No where on the Data Migration program does it show that this HDD will be copied, and furthermore, it says the old drive is going to be wiped. If it doesn't transfer both drives it's not going to work correctly, and I'm sure I'll lose everything. It says that it can do multiple drives but it's not showing up. The HDD is a 400 GB partition, but only about 230 GB is being used. The SSD has about 60 GB being used.
Samsung says:
When the Source Disk has two or more drives this software supports cloning of up to three drives, including the C drive where the operating system is usually installed.
But also..
This software only runs if the operating system is installed on the Source Disk. It does not function on disks that lack an operating system installation.
I think that last rule just has to do with the software itself running, not that it can't support multiple disks. It could be that though I suppose, or if because my partition is too big, or something. UGH I have no idea what to do. I feel like this should be way simpler than it is. I would appreciate any help! Thanks!
Re: the USB adapter. Yes, that's the more or less type of SATA-to-USB adapter that we no longer use. We found those kind of adapters so unreliable that we stopped using them. If we have need for a USB connection we use a USB enclosure or "docking station" to effect the transfer of data via USB. (Let me just add that I'm aware that many users have indicated they find those adapters quite effective & reliable. If you have one and it works, more power to you.) Anyway, that's "water over the dam" since you've internally-connected your intended source drive(s), i.e., the disk(s) you intend to clone.
Until your current post that I'm now responding to I was unaware that you are working with 2 drives - a 128 GB SSD boot drive containing your OS and apparently a HDD that contains some 230 GB of data.
That complicates the situation insofar as the disk-cloning ("data-migration") process goes, however,I'm reasonably sure (but not positive) it can be worked out using the Samsung Data Migration program in the sense that you'll be able to clone both the contents of the 128 GB SSD & the 230 GB of contents contained on the HDD over to the 500 GB SSD. Assuming this could effectively be done, would this suit your objective?
If so, I'll need a little time to ensure this is a workable solution using the SDM program. So let me know if you want me to pursue this.
UPDATE...
Unfortunately (as USAFRet & possibly others have indicated) the SDM program doesn't possess the capability of cloning the contents of two *separate* source drives to a single destination drive. I thought I might have found a workaround where this could be achieved using the SDM program, but it didn't work. At least I couldn't find a way to achieve this.
However...
The disk-cloning program that I use routinely - Casper - DOES have this capability. Using that program it would be a relatively simple & straightforward process to first clone the contents of your 128 SSD over to the 500 GB SSD and then clone the contents (approx. the 230 GB as you indicated that are contained on the 400 GB secondary drive) over to a second partition on the 500 GB SSD. So at that point (following the disk-cloning operations) your new 500 GB boot drive would have two partitions. If, for some reason, you desired to merge those partitions into a single partition you would need to accomplish this following the disk-cloning operation using a third-party partitioning program, e.g., the EaseUS Partition Master program. It's a freebie and generally performs quite reliably re basic partition merging.
But one tip if you do decide to use any program to carry out a partition merging operation. BEFORE you begin that operation ensure that you have a copy (preferably a cloned copy) of your entire system. Merging partitions can be complicated business & I'd like to have a dollar for every merging operation that went awry. And when it does you can just imagine what happens to all your data.
Getting back to the cloning...
Casper does have a 30-day trial edition of the program available at...
https://www.fssdev.com/products/casper/trial/
Unfortunately the trial edition has a ("volume resizing") restriction, the upshot of which will not permit the type of cloning operation in which you're interested. As I've indicated above there's no problem accomplishing what you want using the Casper commercial version which costs $49.99.
I've been using that program for more than 10 years. It's far & away the best disk-cloning program I've ever used. It's chief advantage is its rather extraordinary speed in carrying out the d-c operation. This major advantage lends itself to using the program as a routine backup program of one's entire system since the user doesn't have to expend an inordinate amount of time to backup his or her system. I back up my systems 2 or 3 times a week, frequently daily. Generally takes me about 1 to 3 or 4 minutes to carry out a d-c operation. So it's a strong incentive to maintain up-to-date backups of one's system on a frequent basis.
