I would first go to the MacFixit website. http://www.macfixit.com/ See what experiences others have had and what remedies they suggest. As a longer term solution you may need to get a disk repair utility like Tech Tool Pro or Disk Warrior which may be able to recover your files. And then there is always backup :( Martin ----------------------------------------------------------- For information about MUGLO: http://www.freewebs.com/muglo -----------------------------------------------------------
