Re: How i keep my private keys safe without hardware wallet
1. I have hard disk never used, When I try to use and connect to PC, my hard disk warn me to format it, I can't open my harddisk and lost my data.
you have to read this https://superuser.com/questions/284427/how-much-time-until-an-unused-hard-drive-loses-its-data
3. I think the same as a hard disk, be careful.
Recording book/Paper was good but when the water dries it or fire, so you lost it.

Good point though.
So we can say that no matter which way we choose it's pretty difficult to safe our secret keys. 
I have a reference for you, Are you heard about the steel/metal wallet?, I think it's good for you.
You can write your seed and private key on steel, fire and waterproof for sure.

Wow.. It's really cool. I never seen like this before. Idea is really good and seems like it's a solution of those problem which you pointed above. I don't know how much costly it is or how much easy to use but i love to try once.
