Default Bad Sector in MBR

I have a bad sector reported in the MBR of a Win ME installation. Will a
thorough Scandisk (fix errors) fix the this in the process? I know it could
be a virus reporting the sector as bad but Win ME wants to do the Scandisk
first - so I am going to let it !

Any thoughts appreciated...

Default Bad Sector in MBR

If you didn't already fix your problem, you may want to look into these two
links and see whether you can find the "fitting" software for your case.
Once you have done that, check back here and see if this group okeys it or
not:

Thanks for your reply, fortunately the 15hr Scandisk (!) fixed this error
and quite a few others and all is well. I have made a note of those links
should I need them in the future.

Good to hear you've fixed your problem. Do you remember what has been fixed,
according to the report after the scan? It would be nice to know.
Thanks for the feedback.

Harry.

No. physically bad sectors can't be "fixed", only papered over.

I know it could be a virus reporting the sector as bad


Test that by trying an FDisk (make no changes) from a DOS diskette
boot, so that no virus will be active. If FDisk can read the MBR,
then it's not a physically bad sector, and if it cannot read the MBR,
then it's not a viral effect.

Any thoughts appreciated...


Any physically bad sector is reason to evacuate and replace the HD.

If MBR goes bad, this could preclude access to the rest of the HD at a
file system level. BIOS always looks for first physical sector to
boot off the HD, and can't second-guess this to try the second
physical sector if the first is physically bad. If you boot from
something else, then that will still need to read the first physical
sector to read the partition table stored there, etc.

The best solution in such cases may be to:
- copy off all surviving sectors to an empty same or larger HD
- hand-craft or generate an appropriate MBR on this OK HD
- evacuate the contents of the OK HD

OTOH, writes to MBR may be blocked by a BIOS "boot virus protection"
feature, so look for that and turn it off ;-)
