An offset is simply a numerical address. Think of your hard drive as a giant street: is the first house (sector 0, the Master Boot Record). Offset 1,024,000 is a specific sector 1,024,000 steps from the start. When the error says "occurred at offset 1234567" , it means the tool successfully processed sectors up to that point, then failed when trying to write, read, or verify the sector at that exact offset. hdd low level format tool format error occurred at offset
