just installed windows 10 on a samsung 850 evo ssd, then installed samsung software Magician, there is a tab for Over Provisioning, but when i select this i get a Note saying, using RAW partition may damage your data. OP can be set or cleared only for the last accessible partion, it shows i can set a 10% OP, but can this be set now after my windows OS has been put on this drive ? worried it may damage data, just like the Note warning says ? cheers
