Or another example with the Arch Linux image written to a 4GB USB thumb drive: I/O size (minimum/optimal): 512 bytes / 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes This is an example for a HDD formatted to boot a linux system: Use fdisk to locate all read/write devices the user has read access to.Ĭheck the output for lines that start with devices such as /dev/sd X. Indications otherwise refer to single residual bits reconstruction of byte patterns is generally not feasible. Note that repeating the operation should not be necessary nowadays. However because of block sizes, these sections would only amount to a few theoretically recoverable KiB.Ī single, full overwrite with zeros or random data does not lead to any recoverable data on a modern high-density storage device. Thus a full overwrite would not reach it. If a hard drive marks a sector as bad, it cordons it off, and the section becomes impossible to write to via software.
