Repair Will Not Use Filesort

I searched this forum and tried the advice, but MySQL will NOT repair my table or rebuild indexes without "repair with keycache".

I set myisam_max_sort_file_size to 4T, which is less than the disc space available.

myisam_sort_buffer_size is 1T. max_heap_table_size is 50G, and so is tmp_table_size.

The only errors in the log are complaining about the crashed table.

There are about 700M rows, with a single non-unique index of 6 bytes. Row size is about 88 bytes. The index is disabled. I'm trying to repair the table and then enable indexes.

The host has 32G of RAM. It's 5.1.36 on x86_64.

What do I try next?
