Hi,

I am a newbie and want to know how can I issue SCSI_WRITE & SCSI_WRITE_SAME to the drive with all 0s to erase the contents on the drive. This is going to be a scsi command directly through the drive and not through the host application.

Thanks

On Linux you can use the SCSI generic interface for this purpose.
If you don't want to write the code yourself, look at the sg3_utils
package. There are tools like sgm_dd(8) and sg_write_same(8) for this
purpose.
