I need at least 3 partitions on this drive. How should I create the paritions? Should I use GParted or should I use fdisk? For now I will create 1 partition and test it.
I think that GParted just hacks up an fdisk command but I don't know the set of options that it uses by default. The first partition on the drive is ntfs and needs to be approximately 250GB. Can I use GParted to create an ~250GB ntfs partition that starts at the beginning of the drive?
How do I determine the exact size in MB to use for an ~250GB partition that will be properly aligned (be a multiple of 4096)? I presume that starting it at the beginning will help but what should the last allocated block be.
There are 2MB of unallocated space before the first partition. I don't know if that is the correct amount for the first partition to start on a sector boundary. I get different answers with 512 and 4096 sector sizes. If I know where to start and end the first partition to have it properly aligned, then I think I can go from there.
The output of hdparam seems to indicate that the physical sector size is 512 where I would expect it to be 4096.
