None of the above. Verify merely reads each sector after it is written. If it can be read, verify assumes it is ok. The sector is *not* compared to the data that was supposed to be written. All it does is "verify" that the sectors are readable. -- Leonard Erickson leonard@qiclab.scn.rain.com CIS: [70465,203] 70465.203@compuserve.com FIDO: 1:105/56 Leonard.Erickson@f56.n105.z1.fidonet.org (The CIS address is checked daily.
