Problems during booting and disk write

[Reoyo]

Problem: Unable to write files to hard disk (can read files from disk)

History of the problem:
The computer suffered from random shut downs and some W95 software didn't run any more.
Scandisk was run on the disk. At a certain point during Scandisk surface check, the house circuit breaker switched off all power.
This feature repeated again. Possible electric problems due to heat/dust?The computer was cleaned.
Scandisk was started again and was able to detect some bad clusters, but tripped the house circuit breaker again.
From this last electric incident, unable to boot from the hard disk.
The CMOS setup screen automatically pops up and it is necessary to redefine manually the hard disk. The CMOS battery has been replaced with no improvement.
After manual setup of the parameters, message "non system disk" .
The computer boots correctly in DOS mode from a startup floppy (without having to do anything on the CMOS setup), and it is possible to go to the hard disk and read the files.
But when trying to write anything to the hard disk, in any directory, message "sector missing".
When running scandisk from the floppy on the hard disk, same kind of message "unable to run scandisk, sector missing".
I have a slave hard disk that can be accessed with no problems.
Running Scandisk from the slave hard disk on the master hard disk, again message "unable to run scandisk, sector missing".
Before swapping slave and master disks, does anybody have a suggestion that could help me out of this situation?

The only things that I can think of that would cause the circuit breaker to trip when trying to run scandisk are either an incredibly overloaded circuit or a short in the drive...in any case I think that the drive may be gone either from the original problem or the repeated failures of scandisk and the power being shut off(breaker tripping). If you can access the drive from DOS back up what you can.

You can also try running fdisk_/MBR (with a space instead of the underscore) to see if you can recover the MBR and then be able to boot hte drive....

Any chance the power supply voltage setting is wrong for side of the world? I'm not sure what the setting (little red slider on the back of the power supply) should be for France.
