When I turn on the computer I receive disk write error message (unable to write to disk in drive c). When I continue as prompted I have a Pri Master HDD Error. However, if I run setup I can start W95 in safe mode. Then if I shut down windows and choose restart it will run in normal mode. If I boot from a floppy I can write to drive c (eg. mkdir). I also reinstalled W95 (no change). My question is: what is causing the problem and how do fix it so that when I turn on the computer it will start in normal mode every time?
