master boot record

[*selah*]

I'm looking for a copy of a win98 mbr for a 40G hard drive from sector 1 -
67 for a drive that had the mbr damaged.

Would appreciate any help with this.

Boot from the Win98 Emergency Book Disk (EBD) and execute; fdisk /mbr

Why do you think you need sector 1-67? As David said fdisk /mbr will
rewrite the mbr, but it won't touch the other 66 sectors. Do you have
a drive overlay installed? If so, running fdisk without the overlay
loaded will make recovery even more difficult. Add to that, that if
the ending sector signature word is missing in the mbr, fdisk will
rewrite the partition table.

See this MS article and note the warnings.
FDISK /MBR Rewrites the Master Boot Record

You can get the free utility Mbrwork, it will install a standard
MBR plus other options.

I was able to get the computer to recognize 2.5G by using the sectors from a
2.5G drive (1 to about 66). I want to get the computer to recognize a single
partition of 40G with win98. Then, if it doesn't find the directories and
files, I'll try to rebuild.

That's not the way to go about it. You have probably overwritten
the first partition's boot sectors with incorrect parameters. As it
stand now, you will probably have to restore the FAT32 boot sectors
from it's backup, and then work on fixing the partition tables.

There are many file recovery programs. Here's one, though not free.

Sector 1 is the start of the partition boot record, if you are quoting
Norton Disk Edit terminology, where "Sector" means logical sectors
relative to the partition or volume, and "Physical sector" means,
well, physical sectors.

From here on, I'll assume you mean physical sectors.

The MBR lives on the first physical sector and nowhere else, and
exists outside of any OS, i.e. at the pre-OS system level. So it's as
meaningless to speak of "Win98 MBR" as it is to speak of "Nike foot".

Within the MBR are three things:
1) Code that boots the system, and is usually generic
2) Partition table, which is HD and installation-specific
3) End of sector boot signature bytes 55AAh

You cannot simply paste in the MBR from another system and expect this
to work, because that will kill (2). You can use FDisk /MBR to
rebuild (1), but this will only preserve (2) if (3) is present.

Using tools like FDisk /MBR to rebuild a generic (1) will not be what
you want, if (1) in your case was not generic. Examples of
non-generic (1) - i.e. master boot code - include:
- some boot partition managers
- DDO code overlays to "fix" BIOS limitations, e.g. EZIDE, OnTrack
- boot viruses
- other custom boot code, e.g. encryption

Non-standard (1) may relocate (2), and may sprawl beyond the first
physical sector so that your instinct in preserving 1 - 67 becomes
validated. You can derive (2) from an assessment of the rest of the
HD. Don't do this by creating new partitions of the same size, as
that may kill file system structures within the partitions. In
addition to this, FDisk does probe writes into the partitions
themselves, when it creates partitions, so don't use that.

See http://cquirke.mvps.org/9x/ "data recovery" section. Work
carefully, maintain an Undo trail, etc. Good luck and godspeed.
