Re: hard drives installation

You should connect the grey wire (called IDE cable) to your hard drive and the other end of the same cable to your mother board. also find some other cables attached together (black, red, yellow and black) which have a white plastic at the end and connect that plastic to the right part on the back of your hard disk. place the hard drive in your computer and you are done.

Problem with COMPAQ DC5850 SFF ATH/5000 2GB80GB COMBO WVXP PC Desktop hp compaq dc5850 pc won't turn on after plugging in old hard drive for transfer Posted by Author imageGuest on 1/4/2013

The h3ll you say.

(Kidding around)

Let me see if I understand this straight;

You unplugged THE harddrive to your computer..............

Then you plugged an old harddrive in, and expected to be able to use it.

Expected to because you've done it in the past.


1) Was it an old harddrive you had in the computer, removed it; and had a larger one installed?

2) Is it one that you have had in another computer?

Here's what I know, and why I'm asking;

When Windows is installed on a computer it assigns hash values, to certain major hardware components.
For example;

A) Processor
B) Motherboard: To include the motherboard chipset, and BIOS program. (To include version and date)
C) Harddrive
D) Graphics chipset

Change any two of these hardware components, and Windows will think it is being stolen. Put on another computer.

Microsoft User's License states, "One GENUINE copy of Windows per ONE computer"

(Microsoft makes one Master disk, and from it all GENUINE copies are made, and sold to the consumer)

Now if you stated you installed the old harddrive as a Slave drive; then I could understand.

P2 connector?
That is a Power Supply power cable.

According to specifications the Harddrive is a SATA unit.

Internal Drives - Hard disk controller -SATA 3.0Gb/s NCQ SMART IV

The power cable to it is a SATA power cable,

Probably what your P2, and P3 power cables are.

P1 will be a 24-pin ATX main power cable,

P4 cable,

P5 cable, MAYBE, (Might be P3 too)

And P6 power cable,

This type of power cable is also used on a Card Reader.

To conclude;

A) SATA harddrive has to have a SATA power cable, and SATA data cable.

The SATA power cable's connector is wider, than the SATA data cable's connector.
15-pins for the SATA power cable connector; 7-pins for the SATA data cable's connector,

The above is a general example of a SATA data cable, and it's respective connector on the motherboard.

Your SATA data cable connectors on the motherboard, are of a different style than the above.

You have Four SATA connectors on the motherboard;
1) Light Blue
2) Orange
3) Dark Blue
4) White

Should the sata cable be hooked up to the cd drive or the hard drive and where can i find pictures of where the inside cables should be attached to

One end of the Sata Cable is to be attached to the CD/DVD (Optical Drive) or Hard Disk, whereas the other end is to be attached to the motherboard. The Sata connections on the motherboard are located near the CMOS/RTC Battery as indicated below: - (Blue, White, Yellow and Black, at right-hand top corner)

I need help installing a second seagate 1tb internal hard drive on a compaq presario sr5502fh? dont know where the data connection for the second hard drive goes.

If you haven't changed the motherboard from the time you bought it, then there must four onboard sata connectors on the motherboard, refer below picture; c24ab14.jpg

If you haven't installed four sata drives, then there must be at least 3, you can connect the new hard drive on any port, no matter Master or Slave, Primary or Secondary, it'll automatically set it for you. You also no need to worry about the cable, both the ends are same, it works on any direction; 80e9306.jpg

Same thing with the power cable, you can join it on any power cable.. daeb671.jpg

I hope this helps, if you have problem with this or if in case your motherboard is different, please let me know;
Good luck.
Thanks for using FixYa.

Emachine come up where it ask for me to hit f10 or f2 but it wont do anything. My keyboard or the mouse wont work. My emachine is a w3050. Looking for a diagram of how to hook hardrive cd and just to see...

Are you using a wireless mouse or keyboard? If so try using one that you plug in. As for the cd rom and hard drive all you need is one cable for each device hooked to seperate connectors on the motherboard. Ususally the hard drive will be sata which is a red cable and can only go onto one connector on the motherboard. the cdrom is an ide cable(grey usually) and there is a seperate connector for that on the mainboard.

I was installing a dvd drive, unhooked main power supply in computer, now when I turn on computer it says it needs a systems reboot disc can you help

The computer can't see the hard drive. IF the hard drive is on the same IDE ribbon as the DVD then you have a jumper problem. You need to look at the old cdrom if there was one and jumper new one the same as old one. (Master, slave or cable select) Also while you were digging around inside your computer did you pull the IDE ribbon to hard drive loose from the drive or the motherboard? Are the power connectors still hooked up? Every hard drive ribbon can have one slave and one master drive. Your hard drive should be the master and the cdrom the slave. Some systems are now set to "cable select" that means that the hard drive ribbon has a master connector and a slave connector and that the device (hard drive or cdrom) becomes a master if connected to one connector or a slave if hooked to the other one. If you go into your bios setup when you turn on the computer you should be able to look an see which of the drives or cdroms is hooked up as master or slave. Some will display this information during bootup posting.

Reagarding some Hard disk

You system probably supports IDE hard disks up to 200GB in size. It all depends on what chipset was used on your motherboard. Since it is a PIII system, the 200GB limit is most likely quite solid. Although, you can get past this by installing a PCI card that can handle larger capacity drives. You could also opt for using a SATA controller, but you will be limited to SATA-150 instead of the more current SATA-300 with a PCI interface.

2nd internal hard drive

I’m assuming that you have an IDE hard disk drive ribbon cable with 2 connectors on it. One connector is for the primary or master drive. The other is for a secondary or slave drive. Return all jumper settings to cable select (CS) settings. Connect the 500 to the slave connector and power on computer and enter the set up (BIOS) menu by tapping the F2 key. Hold down the <Alt> key and depress the <E> then the <F> keys in succession. This will force the motherboard to load default settings and also force the motherboard to redetect all IDE devices. Note: The selection for the floppy drive will be reset to ON. If you do not have one then you must disable floppy in set up (BIOS) menu.

Installed a new Optical Drive and require assistance in the wiring

What kind of optical drive? Is this a CD, DVD?, Blue ray,
or an opto-ferro-magnetic floppy?


1) External drive:
a) just power it up and connect it to the PC using an USB
or firewire (1394) cable. If it is USB, make sure your PC
is set up for USB-2 which is astronomically faster.

b) The windows operating system should automatically
detect it and install the low level device drivers.
Then you can run the installation driver CD that came
with the drive.

2) Internal drive:

a) Shut down Windows from the START menu,
chose shut down the system, NOT restart.

b) When it finishes shutting down, turn of the
power at the back (!) of the PC and unplug
the power cord.

Now turn the power switch back on for a few
with the cord unplugged, then shut it off again.

This will drain any internal capacitors inside the
power supply to make sure you don't fry anything
while you poke around.

c) Open up the computer case and look to see where
the other hard drives are installed and physically
mount the new optical drive inside the case.

d) Locate a spare power cable coming from the power
supply (Black, Red and Yellow wires) and hook it
into the back of the drive.

It should only fit one way, but there are several
different kinds of connectors, depending on the
drive type, so you may need an adapter cable.

i) Large 4 pin connector = Red, Yellow, Black, Black
ii) Miniature -//- = -//-
iii) SATA power cable = Small black hooked beastie.

Also make sure the power supply can handle
the extra current, this depends on the other stuff
such as drives and video card you already have in
the machine.

If your power supply is less than 600W on a modern
machine, now may be the time to upgrade it.

I have two video cards, 8 hard drives and a DVD,
so I had to upgrade to a 1000W to prevent my
system from randomly crashing during boot up,
when everything spins up for a self-test.

e) Once the power is connected, you need to connect
the data cable, which comes in a least 3 different

IDE or PATA = Parallel ATA ribbon cable

SATA = Serial ATA cable, small flat cable with a red,
blue or orange jacket, and small black
hooked connectors at each end.

Note that these are a different size and
shape from the SATA power cables.

SCSI = pronounce scuzzi, no longer common.

One end of this data cable connects to the back of the
optical drive, the other to the motherboard, but this is
where it gets more complicated, because the mother
boards are fussy about which slot you plug them into.

You need to follow your motherboard manual here (HP) !

For SATA cables, you have to make sure that the motherboard
can handle them, older motherboards cannot, requiring an
adapter card. Also many of the new motherboards offer
multiple drive configurations such as RAID.

RAID = Redundant Array of Independent Drives:
RAID 0 = STRIPE for high speed at the cost of security
RAID 1 = MIRROR for data redundancy at the cost of $ cost
RAID 01 = Stripe of mirrors
RAID 10 = Mirror of stripes
RAID 5 = Stripe with parity compromise

Anyway, the problem is that on these mother boards some
of the SATA connectors are general purpose (which is what
you need), while others are not (i.e dedicated RAID),

and you may have to change jumpers on the board
or BIOS settings to get it to work right.

Also if the optical drive is to be bootable, then it sould
be connected to SATA1 or SATA2, but that again depends
on the motherboard and the BIOS boot sequence settings.


With the older style IDE or PATA drives, which includes most
optical drives (since SATA is fairly recent), most motherboards
provide two separate IDE ports, each of which can handle a
pair of drives for a total of four.

IDE1, Master = Drive 0
IDE1, Slave = Drive 1
IDE2, Master = Drive 2
IDE2, Master = Drive 3

Each pair of drives shares a single ribbon cable.
Older cables have 40 conductors,
Newer cables have 80 conductors for UDMA.

While the end connectors are the same, only 40 conductors,
the 80 conductor cables have interlaced grounding, which
allows them to transfer data at a higher speed.

Older optical drives used the 40 conductor, newer ones
use the 80 conductor, but there is no harm done using
the 80. If the ribbon cable came with the optical dive,
you can use it if you are plugging it into a separate IDE
port, BUT

Never use a 40 conductor ribbon cable if it is shared between
the optical and the hard drive, because this will slow down
the hard drive to the lower UDMA speed.

Now about the Master Slave thing:
1) Each PATA=IDE port can only handle one master/ slave pair.

2) You must never connect two MASTERS or two SLAVES
to the same cable.

3) The boot hard drive must be a MASTER on IDE1
for most systems, unless the BIOS has a way
remapping them.

4) When a hard drive and an optical drive share the same
IDE port and cable, the hard drive should be the MASTER,
for maximum speed, optical drives are often slower.

5) IDE hard drives and optical drives use a set of
jumpers near the IDE connector to determine if they
act as a MASTER or a SLAVE. This should be set before
you install them, because it is very hard to get at the
jumpers afterwards:

MASTER this forces the drive to act as a MASTER
SLAVE this forces the drive to act as a SLAVE

CABLE SELECT special color coded ribbon cables
(80 conductor) must be used to make this work.
These now come with most new motherboards.

The blue connector at the far end of the cable, away from
the other two goes into the motherboard.

The black connector at the opposite end (near the gray one)
goes into the MASTER drive.

The gray connector in the middle goes to the SLAVE drive.
(both drives should be setup as CABLE SELECT for this to

When connecting the ribbon cable to the IDE drive, make sure
the PIN 1, the marked side of the ribbon goes near the power
connector. On the mother board, the marked of the ribbon
connector goes into PIN 1. The connector should be keyed
to only fit one way, but don't count on it.

Hope this get you started,


BTW please rate my answers.

How to install second internal hard drive

Yes, you can use, Please see label attached to the harddrive for a jumper setting to become primary harddrive.

in the DVD rom there's also a label on it. but the most common setting is slave is in the center.

C S M -

c-cable select
M- Master
the jumper is set to center to become a slave.

the hard drive is should be a master

connecting to the other end of the IDE cable.

HDD-should be a master
DVD rom-Should be a slave

Hope this help.
