[comp.sys.atari.st] How to find bad sectors on Hard Disk?

jlong@blackbird.afit.af.mil (Jeffrey K. Long) (08/15/89)

I have a 30 Meg hard disk that I home-brewed about a year ago.  Anyway, at
the time I got the drive mech.  I lost the list of bad sectors which was
taped to it.  I use ICD formatting utilities on the disk, but they never
flag any defective sectors.  I seem to have a recurring problem whenever I
get my disk just so full, that I feel like it must be a defective sector
that is screwing up my programs whenever I try to load them.  
   Does anyone know of a program that does a good job of flagging bad
sectors on a hard drive?   Any suggestions?  I have reformatted several
times but the problem always seems to pop up latter!   Help!

This may be a weird way to find bad sectors, but MichTron's Tune-Up
program can show a box will shaded areas showing used sectors, if you have
bad sectors you will get 'spots' in this pict after you format the 
partition!  I used this to find a nasty scratch on my hard drive surface
caused by a crashed head - looked like this:

                   ..  
                     ...
                        ..
                          ....
                               (etc)
