I have a packard bell 75 pentium 1 gig hard drive.. I originally had win3.11 on it, upgraded to Win95 2 years ago. I want to wipe the drive clean and start again. I have done it before.. no big deal, but this time I get an error message.. it says, "write protect error writing Drive A. then it gives me the option of Abort,Retry or Fail?? I am at a loss here.. any ideas?
