Performing 3-pass random ASCII character overwrite of a 1TB drive using TechTool Pro on the MacBook Air. This may take some time.....

@peemee You might not need to, here's some reading in the meantime:

Overwriting Hard Drive Data: The Great Wiping Controversy
Craig Wright et al. (2008)
@unixb0y
@peemee USB?

@peemee Just in case: Google scholar found this PDF

@peemee
@schmidt_fu looks rather like this one: https://www.vidarholen.net/~vidar/overwriting_hard_drive_data.pdf
@schmidt_fu
@peemee they look the same to me TBH, but I didn't check on a desktop mac hine.
@peemee
@schmidt_fu Neither did I, I found that with the iPhone SE
@schmidt_fu
@peemee You're right, they look different on the first page. I confused them BC they have the same filename.

Still, the content applies: At todays data densities, there's not enough space to store the same amount of data besides the overwritten data.
@unixb0y
@peemee duuuude USB 2 😂 sooo slow :P
I currently only work with USB 3 or serial :D
Like.. the opposites ^^
@unixb0y I have ordered a replacement USB 3.0 case for that HD. Another HD will connect via T/Bolt 3-T/Bolt 2-FireWire 800 cables & adaptors. I also have a 3 TB USB 3.0 drive for Time Machine.
