Could this be caused by a dirty head?

Not likely but cleaning heads never hurts. Try and see if something changes. Better would be checking with Udma or Sd or equivalent for overall functionality of SA before opening.

It stays busy and won't come ready since it can't read app code.
Won't come out of F level in terminal. And won't ID in SD.

Drive was in a house fire an supposedly working before fire.
No heat or water damage to the computer it was in, but computer
was heavily smoke coated.
Drive appears relatively clean externally.

See what's inside then then proceed. May really be everything. Did you try "jumpstarting" the drive at least to gain some more access to SA / antoher PCB just to see the behaviour ?

I posted a recovery procedure for this problem using a PC3K UDMA on the DeepSpar Forum.
