Why DriveJumper.com?
I bought several used G3
Systems to replace some of my aging computers. I knew
that I could overclock (speed up or optimize) the
processor on these very easily. Or so I thought. Some of
the configurations require 6 jumpers. I couldn't find the
small size jumpers (sometimes call micro 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. These slightly larger
ones are sometimes called mini jumpers. 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.
New SHORTY Size Added!
We now sell three sizes
of jumpers. After buying some new SCSI drives I found I
needed a low profile micro jumper for them. The small
(micro) and the large (mini) (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 $4.99. 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 (low profile micro
jumpers). Email

Most of you are probably
already aware but Seagate bought Maxtor who bought out
Quantum's Drive Division. If you have a Quantum Drive and
need drive hard jumper quantum setting you will need to
use Seagates's site link which is fairly hard to
navigate.
Hitachi bought IBM's Hard
Drive Division. The resources are better organized for
getting information on your drive. See the new links
below.

SCSI
JUMPERS - most
SCSI drives use the small size jumpers, call micro
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.seagate.com/maxtor/
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 DRIVE
JUMPERS - most
IDE/ATA drives use the large size jumpers, usually called
mini jumpers. This is a link to Maxtor's site (which now
covers Quantum). From there you can find the jumper
settings for your drive: http://www.maxtor.com/en/support/products/index.htm.
You probably don't need the link to Hitachi since they
include the settings on the top of the drive but here is
is: http://www.hgst.com/hdd/support/jumpers.htm
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.
