If holding the cable allows it to detect the drive I would have to say you are getting a bad connection.
Try plugging into another sata connection on the motherboard, if that does not work try another cable, if that does not work it only leaves the hard drive. If it is still under warranty you can try to return it to the manufacturer for repair but be sure to back up all your data because there is an excellent chance they will just send you back a refurbished drive.

What is the specific problem you have connecting this internal drive? This is an internal SATA optical drive for a desktop with a standard 5 1/4" drive opening. Many optical drives ship as OEM devices; you will need to reuse the data and power cable from a previous drive or purchase a SATA data cable (7 pin). A locking cable can help keep the cable connected to the drive. If your power supply (PSU) doesn't have SATA power connectors (15 pin), you will need an IDE to SATA adapter. Most online cable shops have the best prices for these.

If your computer doesn't have a SATA port available, you need to add a controller card or use a SATA to IDE converter.

If your case is a ultra-small form factor, you may have a modified optical drive opening. These cases use a slim optical drive (mostly sold as laptop drives). In that case, get an external 5 1/4" enclosure or a USB to SATA adapter.

If you have the drive in the computer, press the Eject button. If that works, then the power cable to the drive is fine. Check the data cable to both the drive and the motherboard. My old computer had SATA connections on the motherboard that would not allow the cable to lock. When I bumped anything in the case, I had to check that the cable was re-secured.

What OS are you using? For most versions of Windows, your OS should have the correct driver or find it with Windows Update (if the computer is on the network). Try launching Windows Update and checking if an optional driver is waiting to be installed. I don't know if Unix or Mac OSX drivers exist for this drive. You may need a different optical drive.

The drive should now be listed in the storage devices (Computer/My Computer). If you can't read files, try another disk. If it still doesn't work, try cleaning the lens or a different drive. Some drives are sensitive to the power supply for burning optical discs.

I hope these suggestions help. Please add a comment with the specific problem and case/OS that you are using for additional solutions.

Fix wireing on p6610f

This solution will be long in length. Therefore a lot of reading.
In essence I am typing out a motherboard manual, of a sort.

May look complicated. This is because I get very detailed.
If there is ANY area I have explained, that you do not fully understand, please post back in a Comment.

I will try to break it down, and/or use a different method of explaining.

1) Let's start with power cables from Power Supply, to motherboard;

HP Support > Pavilion p6610f Desktop PC > Main Support page,

Product information > Product specifications > Motherboard Specifications, N-Alvorix-RS880-uATX (Alvorix),

Looking at the photo of the motherboard, it is 90 degrees to the LEFT; in comparison to how it actually is mounted in your computer case.
(BTX form factor motherboard, and computer case)

I would also like you to scroll down, towards the bottom of the page; and look at the illustration of the motherboard.
(Motherboard Layout)

This way we can compare the two together, as I guide you.

A) At the bottom of the motherboard is the connector, for the 24-pin ATX main power cable.

Yellow/White in color, 24 socket holes. (2 rows of 12)

This is a General example of said power cable, and respective connector on motherboard;

[Note* Color of power cable connector, and motherboard connector; does NOT matter ]

In relationship to how it actually sits on the motherboard, while mounted in Your computer case; you will find it all the way to the LEFT.

Note the Lock Clip on the power cable's connector.
Has a hooked end that goes over a TAB, on the motherboard connector.
When deemed to be plugged in tightly, and correctly; the hooked end will be Over the Tab.

Operates on the same principle as a see-saw on a playground.
Squeeze the top in, to release when disconnecting.

B) 4-pin ATX +12 Volt power cable.

Yellow/White 4-socket hole connector. In the photo, above the processor socket, and to the Right of the square Aluminum finned Heatsink.

You will find it to the Right of the processor, and Below the aluminum finned Heatsink; motherboard mounted in computer case.

General example of said power cable, and respective motherboard connector,

Note Lock and Tab design, just like the 24-pin ATX main power cable.
Power for the Processor (CPU)
PU521 on Motherboard Layout.

That's it for power cables TO motherboard.

2) The front of your computer is the Front Panel.

Header; Rectangular small piece of plastic, that has contact pins sticking up.
You have 3 Black headers on the motherboard, a Yellow header (1), and 2 White headers.
This will become more self-explanatory, as we go on ]

To the Left of the 24-pin ATX main power cable's, motherboard connector; and to the Left of the ram memory slots; are three Black headers. (Photo)

(Mounted in computer case, To the Left/Top of motherboard)

The Orange connector you see to the left of the ram memory slots, is a SATA connector.
Looking at the Motherboard Layout, you will see it is SATA4.

To the Immediate RIGHT of it, is the Front Panel header.

The area of contact pins on the motherboard, that the Main wires from the Front Panel go to; is the Front Panel header.

Main wires such as Power On switch, Power On LED light, Harddrive activity LED light; and Reset switch.

On the Motherboard Layout, it is marked as J18.
You should have a cable coming from the Front Panel, whose plug on connector; matches this header.

Has 9 socket holes. 5 on one side, 4 on the other.
The missing pin in the corner, on the Front Panel header on motherboard; shows you which way the cable's plug connector, goes.

3) I do not know sir, what the long black header is to the left, of the Orange SATA4 connector, is. It is P17.
However looking at the length, you should find only ONE cable, and plug on connector; that matches it.

Should come from Front Panel. (IF it is used)

4) I do not know what the black header is, below J18.
(Again, J18 is the Front Panel header)
I believe with process of elimination, that the cable that goes to this header, will become readily apparent. (IF it is used)

5) There are Four SATA connectors on the motherboard.
SATA1 = Dark Blue
SATA2 = White
SATA3 = Light Blue
SATA4 = Orange
(Photo. Also compare in Motherboard Layout)

This is where a SATA data cable plugs in.
Your harddrive is a SATA unit. Your optical drive (CD/DVD drive) is a SATA unit.

The Harddrive plugs into SATA1.
The optical drive plugs into SATA2.
Any additional SATA units will plug into SATA3, or SATA4.
Example; A second SATA optical drive.

This is a general example of a SATA data cable, and SATA data connector on motherboard,

Note the SATA data cable connector. Has an L-shaped opening.
When connecting the SATA data cable to Harddrive, or optical drive;

Turn this L to the Left, and upside down. The 'foot' of the L always points DOWN.

Note the SATA data connector example shown. This is an OPEN design. Your SATA data cable connectors on motherboard, are a CLOSED design. Still has L-shape on motherboard connector, though.

The SATA data cable connector that goes to the Harddrive, and optical drive; is usually a 90 degree bent elbow.
NOT always though.
The SATA data cable connector that goes TO the motherboard, is a Straight connector.

Between a SATA data cable connector, and a SATA power cable connector; a SATA data cable connector is Shorter in width.
SATA data cable connector has 7-pins.
SATA power cable has 15-pins,

Same L-shaped interface is used.

Most of the time there is a Lock, on the SATA power cable connector. May be a Tab that sticks up, or a small lever, or a rubber 'bulb'. Depress with thumb to connect, or disconnect.

USB headers on motherboard, and USB connectors on motherboard.

Continued in added Comment.

Need wiringdiagram for an ET1161-05 with motherboard

1) Did you unplug it from power?

2) Did you FOLLOW Anti-Static Precautions?

Anti-Static Precautions;
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.
Relieve your body of Static BEFORE reaching inside your computer.

Computer ON a table, computer unplugged from power, computer case open;
TOUCH an unpainted surface, of the metal frame of the open computer case.
This action will relieve your body of Static.

IF you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return.

3) A small primer if I may;

You press the Power On Button. The Power On Button is a plastic assembly, that has the Power On switch inside it.
The Power On Button presses the Power On switch.

Pressing the Power On switch BRIEFLY closes a circuit.
The Soft Power On circuit.
(The Power On switch is a Momentary Contact Switch)

{When the Power Supply, (Computer), is plugged into power, there is a constant 5 Volts present. (DC) The 5 Volt Standby power.
This is used for the Soft Power On circuit }

Briefly closing the Soft Power On circuit, 'excites' the Power Supply, and turns it on. (Almost sounds wrong in so many levels)
The first chipset (I.C.) to receive power is the BIOS chipset.

The Basic Input/Output System program is initialized. (BIOS)
BIOS looks to see what DEVICES are installed, does a Ram Memory count, turns the Processor on, and hands the computer over to the Operating System. (In this case Windows is the O/S)

Driver: A small piece of software that allows the Operating System to communicate with a DEVICE.

My thinking is the Device is the Harddrive.

Either the Power Supply, power cable is unplugged a little bit; and/or the data cable.

The eMachines ET1161-05 uses a SATA harddrive.
Serial ATA

Means it also uses a SATA power cable,

Note that between a SATA power cable's connector, and a SATA data cable's connector; the SATA power cable connector is Longer.

The SATA power cable connector has 15 contact pins.
The SATA data cable has 7-pins,

The SATA data cable connector that plugs into the SATA harddrive, is usually a 90 degree bent elbow connector.
The straight connector end plugs into the motherboard.

(Also note the L-shaped opening, in the SATA data cable connector, shown. The SATA power cable connector also has this L-shaped opening. Mates to the L-shaped connector on the motherboard, or harddrive; or SATA optical drive )

Just physically see if you can plug these connectors in tighter, on the harddrive. (Remember; Power unplugged; follow Anti-Static Precautions)

Also remove all Ram Memory modules. ('Stick')
Now reinstall them.
You may have one that is loose in it's ram memory slot.

Visually inspecting will NOT do. To be assured the Ram Memory module is seated tight in the ram memory slot, you have to remove, and reinstall.

Dvd not working to initiate repair disk- no boot on hard drive

If the internal DVD drive worked previously, try changing the boot order in your BIOS. Depending on your computer, you will need to press Esc, Del, F1, F2 or F10 to access the BIOS. Save the new boot order when you exit the BIOS. If your DVD isn't listed, replace the SATA cable with a new one and make sure that the power cable is fully seated. You can try connecting the data cable to another SATA port on the motherboard. It's possible that the DVD drive failed as well; you can try a different optical driver.

All of the SATA ports should be able to support a boot device unless there is a specific controller/bandwidth sharing issue involved.

If you are using a USB DVD drive, you need to make sure that your motherboard supports booting from USB.

Please add a comment with your computer make/model or motherboard. I can provide more assistance with changing the boot order or determining the limitations of your SATA ports on your system.

IBM thinkcenter says no os after installing DVD writer

Did you install a SATA or an PATA (IDE) drive?

First check that the data cables are connected to both the hard drive and the motherboard. (I know that I've frequently had the cables come loose from the motherboard on my ThinkCentre 8433 when I work in the case.) Also check that the power cables are firmly connected.

Next make sure that you have no disc in the DVD writer. (Or enter the BIOS by pressing F1 (IIRC) repeatedly on start up. Make sure that the hard drive is the boot disc.) While in the BIOS, you can check if the hard drive is recognized by the motherboard. If you don't see the disc listed, recheck the data and power cables.

If the hard drive was working before you replaced the dvd drive, you may have changed the master/slave assignment on the drives (if they are both IDE). Remove the drives from the computer and check the jumpers. (These will depend on the manufacturer. Use either cable select or master/slave as needed) The boot drive should have the jumper set to master or cable select. In the case of cable select, the boot hard drive should be connected to the black connector. The slave drive goes to the grey connector.

If you connected a SATA drive, try swapping the SATA ports (SATA 0 or SATA1) that has the optical drive connected to it.

The next thing to try requires either the Windows install or upgrade disc for your version of the OS (including the Service Pack) or a third party partition manager/repair utility disc. You'll need to reset the boot order to boot from the optical drive (or press F12 on starting the computer). Use the Recovery Console (for the Windows disc) to find any existing OS installs on your hard drive and attempt to repair the master boot record or boot sector if it still exists on the drive. Please add a comment with your OS for specifics on using the Recovery Console. (I replaced my WinXP with Win7 and the methods are different.)

You may have been unlucky and had the hard drive fail while you were working in the computer. See if the recovery partition (F10 on boot) still works or use your system image (Rescue and Recovery DVDs) will restore your computer to the last backup. Try doing the restore to a new hard drive if the recovery discs don't work.

I hope this helps. Please add a comment with any comments that will help me give more specific assistance for your missing OS.

Wen I turn on PC using Windows Vista I get the warning no boot device available. What does this mean?

Hi britchel07,
I see that you are having issue booting into windows on your system.
I can help you with your concern, we can first try to boot into the Hard drive manually, follow the steps below,
1. Power your computer ON then keep on tapping the F12 key on top the keyboard until you get the Boot Menu screen,
2. On the Boot Menu screen select the Hard drive it maybe listed as SATA or HDD, but if it is not listed then we may need to try a different option, on the Boot Menu the Hard Drive should be the first one on the list.
3. Highlight the Hard Drive on the list then press Enter to make your computer boot into the Hard Drive.
if this does not work then your Hard Drive may not be detected by the machine, why I really can't tell there are many possible causes, but we can try other options to see if this can be rectified.
I believe that you have a Desktop machine, we will need to open up the tower to check if there are lose cables inside from the Hard Drive to your systems Motherboard, inside you should see a Flat Orange like red colored cable sometimes Blue that should be your SATA cable going to your Hard Drive from the Motherboard, try reseating the SATA cable to make sure it is properly connected and also check the SATA power cable just to be surem it should also be a black flat cable connected to the Hard drive just right nest to the SATA cable, after reseating the two cables try turning the computer ON again and see if the system will boot into Windows.
If still you get the Error no boot device found then you may need to get a new Hard Drive for your system.
I hope that this will be helpful with your concern, Have a nice day.

How do i remove the hard drive from a hp pavilion a1320n

1) Computer unplugged from power, observe Anti-Static Precautions.

Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out (Short Circuit) the hardware components inside a computer.

Computer unplugged from power, computer on a table, computer case open.
TOUCH the metal fame of the open computer case to relieve your body of Static.
Also before you take new hardware components out of their anti-static bags, or boxes.

If you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return.

HP Support > Pavilion Media Center a1320n > Opening the computer case

Replacing the Harddrive, (Hard Disk drive),

The Harddrive is a SATA harddrive. Uses a SATA 7-pin data cable, and a 15-pin SATA power cable.

Top right photo shows the SATA data cable connector, and cable.
Top right photo below it shows a typical SATA data header (Connector) on a motherboard.

Typical SATA power cable, and it's respective connector,

IF, your SATA harddrive has a connection for a standard 4-pin Peripheral power cable, (Misnomered as Molex), AND a connection for a SATA power cable, ONLY use the SATA power cable.
It will Burn Up the Harddrive if you use both.

If you are putting a new Harddrive in, you will need to have backed up, (Copied) the info you wish to save off of your old Harddrive, first. This is if the harddrive is not bad, of course.

You will also need the Restoration Disk/s to install a new Harddrive, if you are going to just replace the harddrive with a new one. (Larger, or replacing a bad harddrive)

If you do not have the Restoration Disk/s you can obtain them from HP Support.
In the US call 1-800-474-6836
24hrs a day, 7 days a week.
Disk/s are free. Shipping and handling is not.
$17 for a 5 to 7 day ship, $24 for a 2 to 3 day ship.
Have the Serial Number from the back of your computer tower handy to give to the representative.
(White Service Tag. S/N is Serial Number)

If you are not in the US, here is the Worldwide Support contact page,

If you are going to install a new operating system, per se Windows, (Windows 7?), you may have to go into BIOS Setup, and in Boot Order set the first boot device to CDROM, if the disk does not automatically load.
