Dear Charles,

I'll bet you thought you were never going to see this stuff.
I appologize for the delay.  A number of things got in the
way, including the loss of my job.  Anyway, enclosed you
will find the original source files for CSU in Merlin.  I
used Merlin.8 for my assemblies, as I remember.  In the info
directory you will find some more info to check out.  As I
recall, I think you said that you had a manual for CSU.  I
have a v1.5 manual here.  But only on paper, not on disk.
If you need a copy of v1.5 on paper, let me know.  I just
got done using CSU to help me create a dual disk.  I've got
a Quantum 810 meg disk on my Mac, and I reformatted it to
put two 32 meg Apple Prodos partitions on it, so I could
keep my Apple II stuff on the same drive as the Mac.  Apple
File Exchange allows me to look at such partitions from the
Mac and copy over things that I might want to convert to
ClarisWorks, etc.  Note: CSU was written in the days when a
big hard drive was 120 meg.  So if one examines something
like an 810 meg drive, some of the block count displays will
have ?s in them.  The internals work ok, but my numerical
display routine was only set up to display a certain number
of characters, so it put a ? at the front of excessively
large numbers.  I ought to go back and fix that, but phooey.
If you need anything more, let me know, heh, heh, heh.

Chris,

I received the manual and disk for CSU v1.5, and it looks
good.  I have a couple of suggestions if you make any
changes to the manual for future printing:

Page 9, paragraph 2, line 4; "eliminated if" s/b
"eliminated"

Page 9, paragraph 5, line 4; "In other works," s/b "In
other words,"

Page 10, para. 7, ln 2; "will demonstrated." s/b "will be
demonstrated."

Page 12, para. "1. Number..", ln 2; "incremnt" s/b
"increment"

Page 20, para. 3, ln 1; "Revise Name/siz" s/b "Alter
Name,Size" (see pg 19)

Page 21, "DELETE KEY" suggest; "character in back of" s/b
"character left of"

Page 22, para. 2, ln 2; "(32768K)" s/b "(32767.5K)"

Page 22, last para., ln 3; "Revise Name,Siz" s/b "Alter
Name,Size" (-> pg 19)

Page 23, under filecard; "filescard" s/b "filecard"


Also, I think the ability to dump any block on the drive is
a handy feature which is not mentioned in the manual.  I
suggest adding the following around page 9:

------------ At the conclusion of the Get Drive Info
printout, you will see the prompt: 'D' to Dump Partitions,
Return for Main Menu.  Pressing 'D' will produce the 'Input
printer slot:' prompt.  Immediately after you press the
output slot number, which can be a printer or the screen,
the CSU will begin to dump the raw partition block info,
blocks 0,1,2....  The display can be paused by pressing the
space bar.  The output can be aborted by pressing Return or
Esc.  After all the current partitions are dumped, pressing
any key returns you to the main menu.  An extra feature of
this dumping capability is that if you hold down the
Open-Apple key when pressing the printer slot number for
the dump, you will be prompted to enter a beginning block
number and an ending block number.  Use the space bar/arrow
keys to set these block numbers.  (See section on Volume
Size Editing later in this manual.)  This allows you to
easily dump any given block on the entire drive.
-----------

I hope my above comments are of some value.  Thanks for the
manual, etc.  And good luck in the turbulent times ahead. 
:)  And how's mom doing?  :)  Cheers.

your hard drive. Full support of the new Apple High Speed

Chinook SCSI Utilities v1.5


Chinook Technology is pleased to announce version 1.5 of
the Chinook SCSI Utilities, featuring full support of the
new Apple High Speed SCSI Card.

The Chinook SCSI Utilities are vastly superior to the HDSC
Utilities that come with the Apple rev C card.  They also
offer features not available with utilities supplied with
the new High Speed SCSI card.  Some of the features of v1.5
include:

1.  Very flexible partitioning:

Allows the creation of up to 7 partitions on a SCSI hard
drive.

2.  Low level formatting and disk initialization are
available within a single program.

3.  Select desired interleave:

With many different types of accelerators available, a hard
disk manufacturer cannot select the optimum interleave for
each customers system such that they can obtain maximum
performance from their hard drive.

4.  Displays drives bad block map:

This is a summary of all bad blocks that have been
re-mapped by either the manufacturer during drive
verification, or were later mapped out by either the drive
itself or by programs such as CSU.

5.  Bad block re-mapping:

This is the only program available that re-maps bad blocks
to alternate good blocks reserved on the drive.

Note this is NOT the same as marking a block bad using a
bad block file. After a bad block has been recapped using
CSU, whenever the operating system requests to read the bad
block, the drive substitutes an alternate good block.

In other words, after a bad block has been re-mapped, it
ceases to exist.


6.  Media verify using multi-block reads and a multiple
pass option:

Use of multi-block reads allows verification of a 40MB
drive in about 4 minutes compared to about 20 minutes or
longer by Copy II Plus or standard ProDOS 8 utilities.  The
multi-block reads are used only on the High Speed SCSI
card.

The multiple pass option allows the user to have CSU verify
the drive a set number of passes with no user intervention
required.  In this manner, it is possible to verify a drive
continuously (or at least for great lengths of time).


7.  Drive geometry:

Users of the High Speed SCSI Card are presented with
extensive drive geometry information.  Information returned
by CSU includes; drive serial number, number of heads,
number of cylinders, interleave, bytes/sector,
sectors/track and more.


8.  Disk Statistics

Disk statistics include 3 tests.

Test 1:  Read block 0 1000 times.

Test 2:  1000 seeks across 1/3 of the disks surface

Test 3:  Read 1000 sequential blocks.

Test 1 helps us to determine if the drive has disk caching
or not.  If not, the spin speed of the drive is determined
from the results.

Test 2 approximates the average access time of the drive.

Test 3 shows how long it takes to read 1000 sequential
blocks.  This is the number that changes as interleave is
changed.  This test is done in two ways, one using the
standard single block Smartport read command.  The 2nd way
is by using multi-block reads bypassing the ProDOS
operating system.  In most cases, multi-block reads are
almost 10 times faster!


9.  ProDOS 8 interleave simulation.

This test simulates the range of interleaves a drive is
capable of supporting. This way, you don't have to spend
hours re-formatting your drive.

This test does NOT yield accurate results for GS/OS.


Program Compatibility:

Operating system:   ProDOS 8

Computers:     Apple ][+, IIe, IIe (enhanced) and IIGS

SCSI Card:     Rev C or High Speed SCSI  (not all features
are available with the Rev C card).

Supported SCSI Hard drives:

MiniScribe: 8425S, 8051S

Seagate:  ST1XXN, ST2XXN series

Quantum Pro 40S, 80S, 105S

Conner CP3020, 3040, 3180, 3100, 3200

Imprimis/CDC 160MB drive

Syquest removable drive


Chinook believes that any embedded SCSI hard drive that is
compatible with the Apple SCSI card is compatible with CSU.

Sub: SCSI Utilities

I'm writing the descriptions for products in our new "big"
catalog. I just got finished writing the descriptions for
the 3 SCSI Cards we carry and need to say something about
the Chinook SCSI Utilities.

I'm wondering what your software does that the software
that comes with a SCSI card doesn't do? Is it better in
some way?

Thanks for any help you can give me.

Jay Jennings A2-Central

Jay,

CSU v1.5 supports both the Apple Rev C SCSI card and the
Apple DMA SCSI card. It also supports just about every
Apple ever made, including 40 column or 80 column videos,
upper and/or lower case displays, and 'non-enhanced' //e's.
Most of Apple's software only supports your enhanced Apple
//e's or better. CSU uses a filecard interface quite
similar to that of Appleworks.  The primary feature that it
offers is the ability to low level format the drive to any
desired interleave (within the capabilities of the drive). 
In addition, the user can fully verify the drive, including
the partition map portion, and if necessary, bad blocks can
be mapped out by the drive and replaced with good blocks
provided by the mfr expressly for that purpose.  This ends
up being transparent to the operating system and to the
user.  CSU can also allow the user to revise the partition
sizes on the drive, with or without doing a new low level
format.  Although it is strongly recommended that a user
backup his hard drive before changing any of the partition
sizes, it is possible, for example, to move info from
partitions 1, 2, & 3 up to partition 4. Then partitions 1,
2, and 3 can be resized, taking care that their total size
(part 1 + part 2 + part 3) is the same.  CSU permits the
user to selectively high level format only the partitions
he wants, in this case 1 & 2 & 3, leaving partition 4
unchanged and located at the exact same spot on the drive. 
Once the new high level formats are completed, the info can
be moved back to where the user wants.  I did exactly this
recently on my CT-40.  A nice feature of CSU is that it
allows the user to get a tremendous amount of info about
the parameters of his drive, within the limitations of the
particular SCSI card. With the Apple DMA SCSI card, the
user can get a printout of all the major partition info on
the drive, including mfr ID, mfr revision level and S/N,
size of the drive, sectors/track, current interleave,
number of heads & cylinders & tracks & bytes/sector,
current SCSI card ROM#, the Primary and Grown List of
Defects on the drive (from the mfr or mapping out),
smartport device type and subtype, and whether the device
has removable media.  It also should output the SyQuest
cartridge number.  The Rev C card is more limited and can't
display the sectors/track, current interleave, heads or
cylinders or tracks, and the list of current defective
sectors is more limited.  I tried to give the user access
to every possible bit of information that the SCSI
interface is capable of delivering, and then some.  Using
CSU, it is possible to dump the partition map info, or
_ANY_ block on the drive.  In addition, a few speed tests
are available that can help in comparing drives, including
an estimate on raw dumping power of the DMA SCSI in 100's
of K per second (using 12K block reads). The speed tests
are very similar to the Disk.Test program on GEnie.  CSU
v1.5 operates under ProDOS 8, so larger block reads weren't
feasible, but 12K is almost fully converged on the max
transfer of the interface.  The biggest limitation of CSU
v1.5 is that it currently doesn't work with CV Tech's new
RamFast SCSI.... :).

You should ask this same question of Chris Adams at
Chinook, as he may give you a slightly different
perspective.  Also, I've sent copies of CSU to Dennis Doms
and Tom Vanderpool, so you could take a look at it and ask
them their impressions.

In looking back on what I've wrote, I'm embarrassed a bit. 
I rather dislike 'marketing', but I tried to put a lot into
CSU.  It looks like I'm beating on my chest a bit too much,
but it does do a bunch of stuff.  Cheers.
