Disk Tips: Preparing ESDI Drives on a Western Digital 1007V
controller for use with NetWare
Mickey Applebaum
Wasatch Education Systems/NetWire Sysop
Following are instructions for formatting and using ESDI drives
connected to the Western Digital 1007V SE1/SE2 for use with ELS-I
2.0a, 2.12, ELS-II 2.1x, Advanced NetWare 2.0a, 2.1x and SFT
NetWare 2.1x, and NetWare 386. These instructions are NOT a
replacement for reading the manual that comes with the
controller, or for understanding HOW the controller works. These
are just to assist in getting your drives running as quickly as
possible. These instructions assume that you have the version of
the
controller with the BIOS roms installed. Also, be aware that
NetWare 286 has a cylinder limit of 1024, some very high capacity
drives (greater than 512 meg) will still have more cylinders
available even after enabling the sector translation. I have
included the new instructions for preparing these drives for
NetWare 286. Be aware that in NetWare 286 2.0a (whether ELS, ANW
or SFT) there is a limit of 17 sectors per track allowed for ISA
channel disk drives. This controller, as do most other ESDI
controllers, has a PHYSICAL SECTOR PER TRACK LIMIT of 53 Sectors
Per Track for drives greater than 380 meg, and 34 Sectors Per
Track for drives under 380 meg. Please check the jumpers on your
hard drive if it is capable of having multiple settings for
physical SPT and set it accordingly. Using the improper number
of physical sectors per track will produce a drastic performance
penalty and problems with data integrity.
1) Set jumper W1 1-2 ON (This DISABLES the 64k on board
cache)
2) Set Jumper W1 3-4 ON (This ENABLES a 7 byte error
correction ECC)
3) Set jumper W1 5-6 OFF (This ENABLES Sector Translation)
4) Set jumper W1 7-8 OFF (This is a reserved jumper and MUST
be off)
5) Set jumper W1 9-10 OFF (This sets the physical SPT to be
determined by the drive)
6) Set jumper W1 11-12 OFF (This disables the alternate sector
per track and increases the drives capacity by 1/34th to
1/53rd depending on the number of physical sectors)
7) Set jumper W3 1-2 OFF (This ENABLES the on controller
ROM)
8) Set Jumper W7 1-2 ON (This sets IRQ 14)
9) Set jumper W8 2-3 ON (This sets BIOS ROM Address to
CC00)
10) Set jumper W12 1-2 OFF (Sets Primary hard disk address)
11) Install the hard drive(s) and controller into your
computer.
12) Run your set up program and set the hard drive type(s) to
1. 13) Reboot with DOS and run the DEBUG program.
14) At the DEBUG - Prompt type G=CC00:5 (This runs the ROM
format program).
15) You should be presented with a menu, and a parameter table
for the installed drives.
16) Choose Option 7 and select the NON-Translation Option, in
other words, choose the drive type that matches the physical
geometry listed at the top of the menu. Be sure to choose
the standard non-translation mode (the first one after NO
DRIVE or TYPE 0). Exit from the menu program and reboot the
computer.
17) Re-run the DEBUG program and start the menu program again
with the G=CC00:5 command.
18) Choose option 2 (Low Level Format All of Drive). Do option
2 for each drive attached. Respond NO when asked if you want
to format the alternate sector.
19) Choose Option 3 (Mark Defect List Automatically). This
will save the manufacturers embedded defect list. Choose
this for all drives attached to the controller.
20) Choose Option 5 (Verify Drive, All of Drive). This will
compare the Manufacturers defect table to the drive surface
with a READ ONLY scan of the disk media. Any new bad
sectors will be marked and lock out. Do this for all the
drives attached to the controller.
21) Choose Option 6 (Surface Analysis All of Drive). This will
do a read/write surface analysis of the drive and test for
new bad sectors. If it finds any it will add them to the
defect list and mark the sector bad and lock it out. Do
this for all drives attached to the controller. This
prepares a NetWare ready bad track table.
22) This step chooses the Sector Translation Mode you will be
using. It is broken down by NetWare version. Please be
sure to select the proper Translation mode for your NetWare
version.
a) NetWare 286 2.0a (ELS, Advanced, and SFT): Choose
Option 7 and select 17 Sector Translation mode for
each drive attached.
b) NetWare 286 2.1x (ELS-I, ELS-II, Advanced, SFT):
Choose option 7 and select the 63 Sector
Translation mode for each drive attached. For
drives greater than 512 meg see note at bottom.
c) NetWare 386 3.0 and 3.1: Choose Option 7 and
maintain Standard Non-Translation Mode.
This concludes the Disk Drive Format and preparation section for
the WD 1007V controller and hard drives.
NetWare 286 2.0a (ELS, ANW, SFT) generation and preparation
instructions. Do NOT format the hard drive with the COMPSURF
utility as this will wipe out the sector translation, and
embedded bad track info.
1) Generate the OS file as normal.
2) Choose Option 1 on the Installation Menu and create the
partition table on the first drive.
3) Create the Volume Definition.
4) Load the NetWare System and Public files.
5) Choose Option 1 again if you have a second drive and create
the partition table.
6) Create the Volume definition on this drive.
NetWare 286 2.1x (ELS-I, ELS-II Advanced, SFT) with drives LESS
THAN 512 megabytes. Do NOT format the hard drives with COMPSURF
as this will wipe out the sector translation, and embedded bad
track info.
1) Run NETGEN and select the AT-Standard controller card
(ISADISK or ATDISK) in the Disk Controller section (This
Option is NOT available in ELS NetWare as it defaults to the
ISADISK driver).
2) If you MUST do a COMPSURF remember to answer NO or 0 to ALL
questions EXCEPT Maintain Bad Track Info and the last one
(Are these parameters correct).
3) Go into NetWare Installation and create the partition table
and volume definitions.
4) Load the NetWare files.
NetWare 286 2.1x (Advanced and SFT ONLY) and drives GREATER THAN
512 megabytes. Do NOT format the hard drives with COMPSURF as
this will wipe out the sector translation, and embedded bad track
info.
1) From DL 8 (Novell Patch/Driver) on NOVA in NETWIRE get the
files LOADER.ZIP and ISADSK.ARC.
2) Unzip/arc these files and copy the included drivers
(LOADER.DAT, INSTOVL.OBJ, ISADISK.DSK and ISADISK.OBJ) onto
the appropriate working copies of the NetGen diskettes. If
your set of NetWare uses the ATDISK.DSK/OBJ files delete
these before continuing.
3) Run NETGEN and select the ISADISK Industry Standard driver.
Continue the generation as normal.
4) When presented with the NetWare Installation option on the
NetGen menu (on the machine to be set up as the file server,
after the NetWare Operating System file and Utilities Files
are generated, Linked and configured) select the DEFAULT
INSTALLATION option.
5) Create and Save the PARTITION TABLE. This will create a
Non-DOS compatible partition which will not be limited to
the original AT BIOS/DOS Compatible Partition limitation of
1024 cylinders. Exit back to the NETGEN Menu.
6) Select NetWare Installation and choose the CUSTOM
INSTALLATION option. From here you can modify the VOLUME
information as much as you need/desire, but do NOT choose
the PARTITION TABLE option or you will flag the partition
as DOS Compatible and have cylinder wrap problems.
7) Save the volume information you need, then select the
option to load the OS and System and Public files.
8) Continue the Installation procedure and load all the disk
files.
NetWare 386 installation options.
1) Boot with DOS and run FDISK. Create a DOS partition of at
least 2 meg, then flag it as being the Active partition.
Exit FDISK, reboot the computer and format (FORMAT C: /S)
the DOS partition. Copy the files from the SYSTEM disk(s).
2) Run SERVER.EXE
3) LOAD ISADISK
4) LOAD INSTALL.NLM
5) Create a NetWare partition using the rest of the disk
capacity. If you have other drives on the controller
partition them also.
6) Choose the option to do a DESTRUCTIVE SURFACE TEST in
INSTALL.NLM's DISK OPTIONS menu. Do this test on all the
drives attached to this controller.
7) Create the NetWare Volume information and continue the
NetWare Installation.
