You can use FEdit+, SUM Tools, Mac Tools or similar to put a copy of sector 1598 into sector 2. Sector 1598 is a copy of sector 2 (I'm not sure how up to date it is, but it doesn't matter). After that Disk First Aid can repair the disk (if sector 2 was the problem). This works in something like 80% of cases. -- Phil Etheridge (phil@waikato.ac.nz) /\ /\ -+-,--, .--, ._ Computer Services/Mathematics & Statistics / \/ \ / /--< /-- / University of Waikato, Hamilton, NZ. / \/ /__.) \_ /
