Re-Installing Windows 7 Fresh on SSD Questions?

I've the Samsung 850 Evo 500 GB and I've partitioned into two: SSD1 (100 GB) for the OS (Windows 7 Pro) and SSD2 (rest of space) for storing my files. I've over provisioning set to 10% as recommended by Samsung Magician.

I'd like to format & clean install Windows 7 x64 on SSD1 partition again, for some reasons, and I've got a question before I do so:

Will the over provisioned space on my second partition, SSD2, be lost in anyway due to my formatting and re-installing of the OS? and is there any possibility of data corruption/loss on my D: (SSD2)?

You don't want to make the 100 MB partition. When Win 7 installs, it will make the partition itself, if it is needed. If you want to make a partition for your C: drive, you will need about 40 GB for Windows 7. You would add to that the space needed for your programs (maybe an additional 100 GB). You would make the remainder your D: drive for your documents, pictures, personals files. By having a separate partition for your personal files, you will not have to worry about them if at some later point you need to do a clean install of Win 7 or decide to go to Win 10. == In answer to your question, if your files are on the D: drive they will be safe from any formatting on the C: drive.

What is this 100MB partition. Is that a typo.

Looks like it was a typo. It is changed now.

Overprovisioning is a unit matter - not a partition matter.

sorry for the typo and the confusion it made. I didn't mean to ask anything other than making sure that my D: will remain safe but still not sure about the over provisioned data on D:. Is it independent of what is happening on C:?

Many thanks for all the inputs

If you have a C: partition and a D: partition on the same SSD, formatting C: will not erase what is on D:.

Make sure your SSDs are aligned. Always good to check.
