Subject: Reformat hard disk when moved from 386 to 486?

I have just upgraded from a 386 to a 486 machine and just moved my
hard disk over from the 386 to the 486.   Since then I've had some  
intermittant problems with the disk that causes the machine to crash.

I've been told that I should reformat the hard disk when moving it from
a slower machine to a faster one to get the disk sectors properly done 
for the new machine speed.  

Does this sound like a probably cause of timing problems and machine
crashes caused by the disk and a reasonable way to cure the problem?

Is a DOS or OS/2 level format all that is required, or would I need
to do a low-level reformatting as well?

On a related note, if you change the bus speed via setup, do you need to 
reformat then as well?

I'd like to get some confirmation that I need to do this before I go to
the hassle of reformatting the disk.

Thanks for any information you can give me!
