I tried fixboot, and also tried editing the partition boot block to set the
total sector field (which made the partition unbootable so I had to put it
back). Where else might that information be stored?

TIA

Was the value in the boot sector incorrect? What was it? AFAIK, the logical
disk manager has only two places to get the information. The boot record or
the partition table in the MBR. Storing it elsewhere as "data" would be redundant,
and could create a lot of problems.

Run a partnfo and post the output.

Those numbers do match what you saw in your original post.. You
might have better luck changing the PT to match the boot sector and then
either partitioning the remaining unallocated space as a separate volume,
or extending the partition.

The total sectors in the partition table should be (boot sector total +1), as NTFS
uses that last sector for a hidden boot sector backup.
