Well, we didn't have any problem using the extra tracks on our
NBD (Newbury Data) 14380. That is a 380 MB (unformatted) drive,
used with a WD1005 ESDI controller.
 
We just put drive type 32 in the CMOS ram (a drive with 15
heads, but less cylinders and secs/track) and installed
Xenix/386 2.2.1 on the disk. During the install you get to the
dkinit program. There you can specify the exact parameters of
your drive. Ours looks like this:
 
        Disk Parameters         Values
        ---------------         ------
        1. Cylinders            1224
        2. Heads                15
        3. Write Reduce         0
        4. Write Precomp        65535
        5. Ecc                  0
        6. Control              8
        7. Landing Zone         1224
        8. Sectors/track        34
 
The drive itself can handle 36 secs/track, but I believe the
controller can't.
 
Success with your screamer box.
 
If you can't figure it out, send me one of your 25 Mhz cached
386 computers, I will galantly try it for you... (double -:)
