I have an AMD K6 200 desktop with Win98SE, 64 RAM and a 10G HDD Master and 6G HDD Slave. The 10G was added by Best Buy over a year ago and has worked fine. Now I am getting a lot of "Unable to write to disk in drive C: Data or files may be lost. Press any key to continue." I can usually save before I reboot, but not always. It occurs with a variety of programs (Word 97, Outlook Express). I have run Norton Disk Doctor, defragged, etc and no problem is indicated. I have about 5.5G of files on the 10G drive (the C drive) and use the 6G only for backup.I have no network card.
