can paritions effect data in other partitions? or what im asking is, is there any reason ever to format the windows recovery parition and the other little ones (no idea what they are). Im selling the laptop and I want everything squeaky clean
sorry total computer illiterate

also is there any advantage to using shred on the partitions instead of this disk manager thing?
Sure.
Just wipe the whole thing. Boot up a linux disk and run shred.

but then how will it have windows
Windows recovery is if you want to reset the device with the Windows the device came with. The tiny 100MB partition is something Windows makes.
If you want to sell it just perform the device reset as instructed by your manual.

Wipe everything. Get some program to overwrite everything securely.
