RESOURCES FOR FINDING YOUR IDE
HARD DRIVE JUMPER CONFIGURATION
They call IDE drives ATA and more
recently PATA. It is for our intents and purpose all the
same. Do scrutinize the drive itself. Many times the
settings chart is right on the drive.
Hitachi/IBM
- Hitachi bought IBM's Hard Drive Division.
This
link is to their drive setup
site. The jumper
table is on the end of your hard drive.
Seagate/Maxtor/Quantum
- the Seagate
site is crap now. Use my Seagate/Maxtor/Quantum
Drive Table.
Western Digital
-
http://support.wdc.com/
- look on the
circuitboard near the jumper position or click
here for the universal
chart..
Samsung
- had to do their
own thing so pay attention: drive configurations
Samsung
Chart. The
chart on the drive makes no sense. I don't think much of
these drives by the way. They have a high failure rate.
They went out of their way to show you how to limit your
drive to 32GB for what reason I cannot
imagine.
We have recently added a new site
about optimizing your G4 Sawtooth System! Here is my page

duals, complete with chart. Also visit power-mac-g4.com

In a word you can't find
these anywhere anymore and if you do they want you to buy
$50 minimum or pay through the nose for shipping.
When we configure G3
Systems we sometimes overclock (speed up or optimize) the
processor on these unit easily. Or so I thought. Some of
the configurations require 6 jumpers. I couldn't find the
small size jumpers anywhere. Radio Shack didn't have them
in stock. I finally found a source that would sell me in
100 lots but I had to make a minimum order and pay
shipping just so I could get 5 extra jumpers.
I also added some drives
to these systems and on some I had to change the SCSI
ID's and termination and on the IDE drives I had to set
up Master Slave configuration. Again I needed jumpers
only this time a different size. I had a heck of a time
finding the information on setting up the drives.
I started this service
for those of you in this position. Not only do I have the
links to get the information for setting up your drives
all in one place I also added the best sites with
overclocking information.
Now you can get the
jumpers you need without having to pay an arm and a leg
for shipping and get help finding out how you are
supposed to configure your equipment in one easy to use
place.
New SHORTY Size Added!
We now sell three sizes
of jumpers. After buying some new SCSI drives I found I
needed a low profile jumper for them. The small and the
large (gold plated small, tin plated large) come in a
package of 6 for a fair price and no tax except in
Tennessee. They are $1.99 your choice of sizes.
The new SHORTY size we sell 4 in a package for $1.99. We
include shipping in the price (we mail your order first
class). If you aren't sure what size you need order the
combo pack which includes 6 each small and larger for
$2.99. The SHORTY jumpers we only sell separately
and you will know if you need these since they are so
small and SHORT. Email

SCSI
JUMPERS - most
SCSI drives use the small size jumpers. This is a link to
Seagate/Maxtor/Quantum
site. From there
you can find the jumper settings for your drive Click
here for drive hard jumper maxtor setting
Maxtor/Quantum
- http://www.maxtor.com/home-en-us.html
SCSI drives use jumpers
for several functions. The main reason most people change
the jumpers on a SCSI drive is to give it a different
SCSI ID. There are usually 3 locations and on the Quantum
for example they are labeled A2, A1, and A0. Default is
generally no jumpers which makes the drive 0. By adding
jumpers to different positions you can number the drives
anywhere from 0 to 7. The main thing is to make sure that
the number you make the drive is different than any other
device on the chain. For example a typical installation
would be a base drive with the number of 0, a CD drive
with the number of 3, a zip drive with a number of 4, and
a scanner with a number of 7. If you were to add an
additional drive to this chain it would have to be
numbered 2,5, or 6.
The other reason to
jumper a drive is for termination. It seems systems like
to know where the beginning and ending of the chain is.
To accomplish this the first device on the chain
generally should be terminated as well as the last
device. See the notes on your system for specifics. I
like to have my scanner as the last device in the chain
and I always terminate it. Want to know more about
termination? Try http://www.scsita.org/aboutscsi/SCSI_Termination_Tutorial.html
Startech has a SCSI
School which is a great place to learn about all the
flavors of SCSI http://www.startech.com/scsischool/
Another great area to
research: http://scsifaq.org:9080/scsi_faq/scsifaq.html
IDE/ATA/PATA DRIVE
JUMPERS - all
IDE/ATA/PATA drives use the large size jumpers.
IDE/ATA drives
generally have 3 or 4 jumper positions. If you have two
drives on a bus you must configure the drives in a
master/slave configuration which may require you add a
jumper to one drive or the other. See your drive
instructions or try the appropriate site listed in the
links.
SPECIAL NOTE:
ON Power
Macintosh G4 systems produced after 2002 which includes
late model QuickSilver G4's, Mirror Drive Door, iMac
G4's, Mac Mini"s, iBooks, Powerbooks having Boot ROM
Versions 4.33 or later you should use
CABLE SELECT on all drives including
opticals. This
includes all G5 model opticals as well. The G4 units do
not have the 132GB hard drive limitation and can use the
larger IDE drives. Do remember though that if you plan to
boot info OS9 on units that are capable, the maximum
partition size is 190 GB.

WESTERN
DIGITAL BUYS HITACHI
My
least favorite drive company is buying my next favorite
drive brand. I personally still prefer Seagates when I
can get them but substitute Hitachi's and consider them
about the same. Read about the purchase at
Bloomberg.
The thing these days is nobody is making all the sizes of
IDE drives we use on many of the older Macs we build and
sell. We more recently have been having trouble finding
Pioneer IDE SuperDrives.
SEAGATE BUYS
MAXTOR FOR 2 BILLION
Most
of you that read my tips know that I am a Seagate and
Hitachi fan and until something changes they will be my
hard drive of choice. Maxtor was always second on my
list, although these days their new technology is moving
them to the top of the list again. Western Digital is
last and I still have a low opinion of them but they are
cheaper. The reason I think my opinion should count is
that out of the 1000's of systems we get per year we pull
and test the drives out of each one. I see what goes out
in the trash. I felt about the same way when Maxtor
bought Quantum, which was my old number 2. I hope Seagate
keeps the quality control that Maxtor had and continues
to produce at least that quality of mechanism. I shudder
to think about web access to jumper charts and other
drive info during the changeover. Some folks look at the
specs on how a drive is rated which are made up by the
factories and are meaningless. Other site the warranty,
and those with the longest being the best drives to be.
Not with my data. What good is a warranty when my server
is offline and I am losing business, or I have to spend
half a day recovering my personal system.
