Some combination has to be enough. Because otherwise you could use that property (plus error resistance coding) to store arbitrary amounts of data on your hard drive.
If you are able to get at the entire physical media then a certain combination of high and low bit writing is necessary or one can read some previous bits with specialized hardware. There is a DoD standard for writing enough combinations. But with modern drives you are not getting at the physical layout. The drive may detect an error and remap surrounding data for you. Consequently, some data surrounding some badbloc…
Yes, the badblocks argument is a good one.
I guess the right solution would be to store your data only in encrypted form on your drive. Then you will only have to worry about safely deleting the key.
