To be honest you can get much cheaper by going into your local hardware store or supermarket with the HDD enclosure and finding a cable that fits.

How do i put the power cables on their place


Hi
There are usually two power connections to a motherboard
First, a 20 or 24 pin supply for the main supply to the board, usually situated near the edge of the board nearest the front of the computer.
Second, a 4 or 8 pin supply for the CPU, usually located near the CPU socket, and the back of the computer by the keyboard & mouse ports.
These are plastic moulded plugs which cannot be inserted the wrong way round so do not under any circumstances try and force them into their sockets.
Picture 1, 25336079-0zjgx3l01ilvrugbqurlbg5i-5-0.jpg shows a four pin CPU socket
Picture 2, 25336079-0zjgx3l01ilvrugbqurlbg5i-5-2.jpg shows an 8 pin CPU socket
Picture 3, 25336079-0zjgx3l01ilvrugbqurlbg5i-5-5.jpg is a 24 pin main power supply socket.
Hope this is helpful, if so would you please register that with Fixya
Cheers

What is the difference between a external hard


External hard drives contain a power supply to operate a standard hard drive in a case. It usually connects to a USB port. Usb drives get their power from the wire that connects it to the USB port A regular internal hard drive gets it's power from the computer's power supply wiring. The data cable is either a flat ribbon cable or a 6 pin cable that connects directly to the mother board.

I'm trying to install a Western Digital Serial ATA Hard Drive into the external hard drive enclosure. There are no instructions as to what cables need to be attached and to where


USB external hard drive cases are supplied with SATA and power connectors attached to the circuit board in the case. If you canot connect it to the SATA hard drive then you may have the wrong drive case, your case may be a IDE or SCSI type.

I have several computers at home, and none og them can recognize this portable device. Hitachi 250 GB Mod: SDM/250RW


1) Power:

It may be the problem that occurs with a lot of USB powered devices jrherrer. Not enough power provided.

The USB cable plugged into the computer, provides signal wires for transferring information back, and forth, and also provides 5 Volts DC for power. (Two D cell flashlight batteries produce 3 Volts DC)

http://en.wikipedia.org/wiki/USB

[ Below shows the Signal pins, and the Voltage pins of the USB B Mini style connector, (Male), used to connect to the SimpleDrive Mini external harddrive,

Pin 1 is for the 5 Volts DC Positive (Wire color - Red)
Pin 2 is for the D- Signal (Wire color - White)
Pin 3 is for the D+ Signal (Wire color - Green)
Pin 4 is not connected. (Or sometimes joined to Pin 5 with a Resistor)
Pin 5 is for the Ground (Wire color - Black)

Just added info in case you wanted to know ]

From what I see the SDM/250RW has a USB port on the side, and a DC Power Jack, used for an AC adapter, also.
(Round port with a pin in the center)

http://www.hitachigst.com/tech/techlib.nsf/techdocs/0C876B7AB91B23988825773F006BEA02/$file/SD_Mini_DS_final.pdf


From what I see stated from Hitachi, and sellers on the 'net, the AC adapter may not be provided.
Many of those who provide a review state that both the USB cable, and the AC adapter is needed to provide enough power. Seems to be a power hungry external harddrive

It's a 2.5 Hitachi SATA laptop harddrive inside that external case. (The Harddrive is 2 and a half inches across in Width. Common size used for laptops)

When using an external device powered by a USB cable there are general guidelines to follow,
A) The USB cable should not be more than 2 feet in length
B) Connect the device directly to your computer, instead of through a hub, or other device, unless the USB hub has it's own power.


2) USB cable:

Could be a faulty USB cable, although I imagine you have tried different ones by now.


3) Interface Circuit Board:

The Hitachi SATA 2.5 harddrive inside the SImpleDrive Mini SDM/250RW, plugs into a small circuit board located inside that external case.

Components on the circuit board may be fried, or the Harddrive may have come loose from the interface.

Loose from the interface
To explain;
The back of the harddrive has connector pins sticking out.
The interface has socket holes which the pins insert into.

Faulty circuit board
The external case of the SimpleDrive Mini SDM/250RW can be carefully opened up, and the Hitachi SATA 2.5 harddrive extracted out.

Another inexpensive external case for a 2.5 SATA harddrive can be procured, and the Hitachi harddrive put in it.

I have an IOMEGA 60 GB HDD probably from 2003. Power supply input is 5V / 1A. I mistakenly plugged in 16V / 4.5A from IBM PC power Adapter. Any suggestions how I can extract data or which parts to...


Just take the drive out and put it into a new enclosure would be your cheapest option to keep it portable

I label all my PSU's with a dymo label maker to try avoid the situation you just had (fingers crossed)

Or you could insert the drive into a computer that has a suitable interface eg. SATA or IDE

Having a similar problem with the La Cie 500gb. Powerbook G4.


The problem that has been inherent with all LaCie external harddrives, is the interface in the case itself.

Interface:
All external harddrives have a Style of harddrive that is used in a laptop, or one that is used in a desktop computer.
Laptop harddrives are 2-1/2 inches across in width.
Desktops are 3-1/2 inches across.
Your LaCie will have a 3.5, (3-1/2) inch desktop style harddrive, inside the case.

There are two main Types of harddrives.
IDE and SATA. (There is also a newcomer. SSD. SSD isn't being used in LaCie external harddrives at the moment, to my knowledge)

Your LaCie will use a SATA harddrive inside it.
This is an example of an average SATA harddrive,
http://en.wikipedia.org/wiki/File:Hdd.jpg
The photo of this harddrive is tilted at an angle, that doesn't readily show the interface connection, but it helps to explain.

At the bottom of this harddrive in the photo, and to the left, is the interface area.

Viewing the harddrive, look at the four metal pins on the extreme right of the harddrive. To the left of these pins is the Jumper pin area. (Has a white jumper on two of those pins)

To the left of the Jumper area is an opening, and to the left of that, is a long slot. The first small slot area is for the 7-pin Interface cable.
(Data cable) The next slot to the left, is for the 15-pin power cable.

This 7-pin Interface mates up to socket holes in a connector, of the case of the LaCie external harddrive.

It is this interface connector, inside the LaCie external harddrive case, that is the problem.
Solution?
Buy a quality, in-expensive External Enclosure, take the harddrive out of the LaCie, and install it in this enclosure.

Examples of 3.5 Sata External Enclosures,

(From $15 to $35, is a good range for a decent external enclosure)

Nexxtech 3.5" Hard Drive Enclosure (NHDE35)


I'm not saying this will solve all problems, but it solved it for me. I am running Vista and got this to work following someone's instructions from another forum.

The slot in the enclosure that you plug the hard drive into has one set of holes fewer than the hard drive has pins. This means you can plug the hard drive in two ways "left" and "right" if you will. I had to plug my hard drive in so that the unused pins were farthest from the power cable that plugs into the hard drive.

Incidentally this made the screw holes line up better, too.
