I tried for 100000000000 bytes a week ago. I let a C++ application run overnight and just fill up my hard drive. It stopped a bit short because Mac OS started filling up the swap. I agree, a checksum system would be nice. But I'm still waiting on my attempt at this record.
As co-editor in chief of my high school's paper, I will figure out a way to beat this!
How do you actually prove this record if you're opening a huge document? Let's say I make a 90 GB file full of the letter A. How do I prove that the entire 90 GB is full of 'a' and not other letters? This record is only limited by hard drive space and the size of 64-bit integers for me.
I WILL beat this record. I have my ways.
Ok, it's time for me to play. Consider this broken.
