Linux noob here. Usually in Windows if I have a 1TB SSD, I make a 250GB partition for Windows and all of its things and I use the rest for a second partition where I install my stuff and store my files.
Usually in case Windows decides to go belly up, I still have my files. In more than 20 years it has never happened but I've always done it like that. I mean if Windows goes bad, I can still remove the drive and insert it into a different PC and copy my files away.
Should I shrink Partition 3 and make another one? Or keep it as it is? If I would, I read that I need to boot with a live usb to be able to shrink it. What kind of partition would I make?
I think it's a little buffer to make sure the actual blocks on the disk exist and line up with the partition start, but definitely don't quote me on that
I don't know that's how Pop OS configured it. I gave it the entire drive and it made the partitions and everything.
There has to be a small unused area at the start for the partition table. 2MB is far more than is needed for that, but leaving less would tank performance due to the fs blocks and disk blocks not being aligned.
