SEAGATE BUYS
MAXTOR FOR 2 BILLION
Most
of you that read my tips know that I am a Hitachi fan and
until something changes they will be my hard drive of
choice. Maxtor was always second on my list, with Seagate
always 3rd, 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.

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 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.
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

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. 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

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. 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.
