NOTE: SpinRite is not free (see grc.com) Also, maybe I should mention my own LiveCD/Rescue disc (which does have the= badblocks program you're looking for): FreeBSD-9.0_Druid-1.0b60.iso or FreeBSD-8.3_Druid-1.0b60.iso (the former for 9.x and the latter for 8.x). > Which pattern is better for format 0x00 or 0xFF or one after another or > dont care?
