[comp.sys.ibm.pc] recovering FAT of a damaged diskette

dipto@umbc3.UMD.EDU (Dipto Chakravarty) (05/18/88)

Two questions for knowledgable DOS users --

(1) File Allocation Table:
    ---------------------
I understand that there are two FAT-s on the diskettes.  Now, is there 
a quick + dirty way to fix a damaged disk whose FAT has gotten screwed
up ?  In the past two months we have had five such incidents, where a 
disk could not be read.  Attempts to recover damaged sectors by using
tools like Norton Utils and PC-Tools were unsuccessful. Please e-mail
some wisdom to me. 

(2) Low-level format:
    ----------------
A hard drive manager software, called PC-Lock was installed on a 20Mb
drive. Now the user, wishes to disable the password. The user took the
program off (may be incorrectly!). Then the drive was formatted again.
Now, even after repeated re-formatting of the drive, one still gets 
prompted for the password. What do you think is the problem here? Will
a low-level format (thru the 'debug' utility) take care of this problem?
Any suggestion/wisdom will be appreciated.
