When I read on websites one should do a low-level format, what do they mean?
Is that equivalent to one of these? 1) dd if=/dev/zero of=/dev/sda 2) echo -e "o\nw" | fdisk /dev/sda 3) dd if=/dev/zero of=/dev/sda1 4) mkfs.ext4 /dev/sda1 If so, which one? If not, what is a low-level format? >From reading wikipedia[1], low-level sounds like it is none of the above and either is done by the manufacturer or not at all. The article makes it sound as if when people say low-level formatting, they mean a combination of 1, 2, and 4, which I tend to call "wiping", "partitioning", and "formating". Is that a fair conclusion? BTW, the reason I am asking is because I came across a blog that recommended low-level formatting an SD card before using it in a digital camera. Hope everyone is having a good holiday season.
