SSD drive on top of the HDD - what about the partitions?

2017-03-30, 15:35 PM

I am running a 2TB drive on my Lenovo desktop. As it happens, it's my office machine and therefore I use very little of the space - around 60GB. I decided to speed it up by adding a 128GB SSD drive for the system, while keeping the old drive as a backup location.


I am trying to work out how to efficiently clone the drive. I currently have 5 partitions listed in Windows 10, in order:

1. 1000MB Recovery Partition

2. 260MB EFI System Partition

3. 500MB OEM Partition

4. 1.8TB Boot/Page File/Crash Dump/Primary Partition (my C: drive)

5. 24.41GB Recovery Partition


My intention was to shrink 4 (my C: drive) to 128GB and clone it onto the SSD. I am hoping that:

a) I will be able to boot my Windows 10 from the SSD as my primary

b) I will use the remaining 1.676TB of 4. to create another partition, call it D: drive, that I will use as a backup destination for my SSD.

c) If anything goes wrong with the SSD, I simply skip it in the boot sequence and boot from 4. on the old drive - and use the archive on D: to recover data.

d) Should it happen that I need to access any of the recovery partitions, I boot from the old drive as they are still there.


Will this work as intended, or am I missing something here?


Thank you!

Hi adrug , 


Welcome to the Community Forums. 


I suggest that you dont change the partitioning of your HHD as this may compromise the hidden partition for One Key Recovery factory reset. 


Depending if you want to your SSD to have a hidden partition ( would take extra space on the 128GB SSD) then cloning would be a option . Back up your HHD first on a different location and factory reset it first so that it would all be fresh for cloning without any non essential data eating up space before proceeding. 

Review this post here and here for further reference .  


Another option is to simply back up the files , reset hdd to factory settings , create a recovery media , use that recovery media to install Windows on SSD  , change boot partition in the BIOS to boot on SSD .


This way , you have a backup recovery media installer , more space on the SSD (without hidden partition) , a peace of mind knowing that if SSD fails to boot, you can switch to your HDD instead ( use current d partition as destination data drive with both a)b)c)d) .intentions. Test SSD and HDD (with OKR factory restore tested) separately for boot functionality.


Hope this help answer your query.
