Install OpenBSD on a usb stick, run OpenBSD from there and use dd to write zeroes to the disk. If the disk has bad blocks you will see similar errors in the dmesg. You can do the same with linux. Sometimes bad units pass the checks of badblocks programs because these run read-only tests by default and the flash controller lies. You only see the bad sectors when you try to write to the disk. -- Juan Francisco Cantero Hurtado http://juanfra.info
