Hi,

  I just got an used AT&T 7300 PC. I think the data in the hard disk has been
serious damaged. So, I try to reformat the hard disk. I used the Diagnostic 
Disk and try to initial HD but it reply me a message "WINCHESTER:Error during
format:Response = 4". I don't know what is that means. Can anyone help? And
can anyone tell me 
1) How to reformat my hard disk (20MB)?
2) The procedure to reinstall UNIX System.
3) If the data in my disk, like Diagnostic Disk is damaged. What should I do?

  Thank you for your help!!!
