NickyB :
I'm using magician 4.2.1. At a loss as to why it's not working
Me too.
But when Microsoft were remotely on my computer the other day trying to get Windows 8.1 preview to work with my Windows 8 Pro code, they changed my SSD to not have over-provisioning and deleted some part of a partition via windows system Disc properties or something.
They left me to fix it myself after quitting and telling me to do a full re-install of Windows 8 Pro on top of Windows 8.1 pro? Preview. Over a hundred hours wasted, and over a hundred hours more work to go to get my computer back to how it was when W8.1 preview was working properly till I updated my Win 8 Pro code into it; when it all stopped playing nice.
I created a similar partition (its in black on the drive) but dont know what else to do.
Like you said; something to do with RAW data; as the Samsung SSD Pro and W8 use some specific drive arrangement detail or other.
Anyway; its something to do with the format of the partition not being correct; I`m fairly certain.
