I have a Miniscribe 44Mb 28ms hard disk. It is 2 years old.
Lately I have lost some sectors that became bad. That happens during my 
autoexec.bat at booting. The weird thing is that it seems to keep happening. 
The first time, I went into Norton, with DT I did find bad clusters, moved the 
file to OK clusters and marked 
the bad clusters as bad. Now it seems to keep happening from time 
to time. During autoexec.bat I get (NOT ALWAYS) an "error sector not found". 
Most of the time, if I hit retry it then executes properly. 
Sometimes I have to do a CTRL-ALT-DEL to make it try to reboot. When I do a 
disk test with Norton, it finds nothing wrong with either files or clusters.

Has anybody had experience with such intermittent problems? I used to think 
that a sector IS or IS NOT bad, not that it sometimes is and sometimes is not!
Is this a sign of upcoming major problems such as a final head crash?

PS. Also, in the last two months, the hard disk has exhibited some vibrations 
(at times). A muffled noise similar to a circular saw in the next room!

Anybody has any ideas?
Thanks
Eric
