What are the parameters your taking as defaults?
Maybe the formatter is having trouble with a bad block.

| This may not be of much help, but when I used to work for
Integrated Support Systems, I had to format hard disks occasionally,
and I ALWAYS had to tell the formatter to flag off the bad sectors.
It is possible that your formatting program is attempting to format,
then verify a bad sector, and when it won't verify, it keeps trying
to format it. I suggest that you write down the bad sectors, and
set up the bad sector table in your formatter. (I hope it has one)
Let me know if this is of any help.

1706.3 | PREP | MTWAIN::MACDONALD | WA1OMM 7.093/145.05/223.58 AX.25 | Wed Sep 21 1988 15:43 | 5 |
| Sounds like you haven't run the PREP program that comes with the
A2090 controller. The prep program asks you to input the bad block
information.

I have run PREP but I'm not quite sure of the format.
The tag on the disk has several columns:
Cyl Hd Sec Bytes Bytes/In
I know what Cyl, Hd and Sec is. What about bytes and bytes/in?
PREP asks for Cyl, Hd and offset. I'm not too sure what they mean
by offset...

> Cyl Hd Sec Bytes Bytes/In
This is the standard way of listing defects.
"Bytes" is the length in bytes of the defect.
"Bytes/In" or Bytes from Index is the starting location, reference to index,
of the defect.
Offset probably wants the Bytes/In field.

1706.6 | I'll try a RD53 | RBW::WICKERT | MAA DIS Consultant | Thu Sep 22 1988 12:04 | 17 |
|
It seems the format commands hangs a different blocks - last night
it didn't get past block 20!
So, I'm going to try an RD53 from work. The problem is I don't know
what type of drive it is to tell PREP. Do I need to use "UNDEFINED"?
If so, does anyone know all the answers to the questions? I guess
I need # of Cyls, # of heads (8, I think) and something called the
write comp cyl?
Also, does anyone have a 53 running with a 2090? I know it should
work (ST506 is ST506, right?) but I'd feel better knowing someone
had already done it.
Thanks,
Ray

All Set. He sent mail...
FWIW: RD53 is a Micropolis 1325, 8 heads (0-7) and 1024 cyls (0-1023).
It does NOT use precomp so set it to some value greater than 1023
(or turn it off).

After 3 attempts at getting these two lines in!
RD31 - Seagate ST-225. 4 (0-3) heads, 615 (0-614) cylinders, precomp at 256.
