    I have a disk problem which I have been unable to solve. I would
    appreciate any ideas.

    My configuration: ALR386 AT Clone, WD1006RAH 1:1 Interleave RLL
    disk controller, Microscience HH1050 Disk (1024 Cyl, 5 Heads).Rom
    Bios: By Phoenix ALR number 1.10-01 (latest) supports this disk as
    type 37 (1024 Cyl, 5 Heads, 26 sectors, precomp -1 (what is
    precomp?)). Setup says drive type is 37.

    I run a low level format (with WDFMT) with above parameters.
    Everything is OK. Next I boot ms dos 3.3 from floppy (OK) and run
    FDISK. FDISK terminates with "error 2003: Integer divide by zero".

    I also tried low level format with Spedstor and boot with Compaq
    DOS 3.1. In this case COMPAQ DISKINIT terminates with "divide
    overflow".

    Finally I used Spedstor's partition editor to "high level" format.
    This works but when I boot with the spedstor disk driver I get
    messages "physical size not equal logical size". In this case I
    ran a diagnostic (PC Technician) and it says my C drive has 0
    heads. Is this the zero that causes the divide overflow?. Where
    does it get the number of heads?

    Help!
