I need a new internal power supply for my 2tb external its an Iomega prestige. I just want the part number for it so i can order a new one.


There is no internal power supply. The unit gets it's power from the computer. A USB port has 5 Volts DC.

Inside that external enclosure of the IOmega external harddrive is just an ordinary harddrive as used in a desktop computer. A SATA harddrive.

The harddrive plugs into a small circuit board with an interface on it, or there are cables, (wires), which come from the circuit board, and plug into the back of the harddrive.

It is this small circuit board that is usually the problem.
The solution to this problem is to simply just buy an economical external enclosure, and install the harddrive out of the IOmega into it.

Just one example from a quick search for an economical SATA 3.5 external enclosure,
(Note*
A laptop harddrive is 2.5 inches across in width. 2 and 1/2 inches.
A desktop harddrive is 3.5),

My external harddrive keeps restarting...what would cause this to happen?


being an external hard the problem could be with the power supply unit PSU

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ?
hope this helps

Power supply will be the first palce to look, it should have 5,12v, and 24vdc at the output connectors. Look for bad caps with bulging tops, burnt parts, blown fuse.

Maxtor external hard drive cannot be detect


Hello,

First of all make sure that the USB port that you are using to connect it to your PC is a USB 2.0 port, and not USB 1.0.

Also if it came with an external power, connect it to the external power before putting on your PC.

This is because the voltage supplied by USB 1.0 is lower than that of USB 2.0 and therefore might not be enough to power up your USB Drive.

After making sure about this, power up your system, and plug the harddrive, then Right-Click on my computer icon, select manage, then go to Disk Management Option.

On the Disk management option Page you should see ALL the drives installed on your system, including the hidden ones, so what you will just do is, try and locate the one representing your harddrive, and right click on it. then select "Change Drive letter and Paths", and give the drive any new, unique letter (i.e alphabet) different from the ones already on your system, and click on OK.

This should make your harddrive to be detected automatically.

Hope this helps you out.
Goodluck!

My unit is not powering on. I plugged in an 18v power supply into the unit and it was on for a few seconds and then shut off. Did I burn out the unit?


thirdjonesbo,
This solution will be rather lengthy. I apologize for the length of it in advance, but feel it is necessary to explain my possible solution.
Please bear with me.
joecoolvette

Inside the external harddrive case is a SATA harddrive.
The SATA harddrive plugs into a small circuit board, via an interface connector, OR small cables.

[Interface Connector.
On the back of a SATA harddrive are metal pins that stick out. The ones to be concerned with are the 15 pins for Power, and the 7 pins for Data. The 15 pins for Power are grouped together, as well as the 7 pins for Data. An Interface is simply a connector that has socket holes in it, that the pins stick into.

If you have never seen a harddrive, much less a SATA harddrive, the above statement will be as clear as mud.
Let me show you the pins on the back of a SATA harddrive, to help clarify this,

http://www.interfacebus.com/SATA_Pinout.html

Under the heading - Serial ATA Signal Assignments, view the illustration.

On the right you will see the Power Cable, headed towards the Power Connector. If you could enlarge this illustration you would see there are 15 pins.

On the left you will see the Signal Cable, headed towards the Signal Connector. Again, if you could enlarge this illustration you would see there are 7 pins. Signal is also Data.

(Data = Information. Information is processed back, and forth to the harddrive through this cable)

An Interface connector is rectangular in shape, and has socket holes to fit these pins.

Or, as stated above, it may have two small cables as shown in the illustration, and they plug into the Power, and Signal (Data) pins.

Either an Interface connector, or two small cables lead up to a small circuit board.

IT MAY BE that you are fortunate, and the circuit board bore the brunt of the overload of voltage, and did not get to the SATA harddrive inside.

My suggestion would be what I would do myself. This suggestion may not be what you would do.

I would open the external harddrive case, and look for obvious signs of electronics failure on the circuit board, and on the harddrive itself.
The harddrive also has a circuit board. It's on the bottom of the harddrive.

If you see obvious signs of damage such as,
1.Black marks on any of the various electronic components, or 2.Electronic components that have melted, swelled up, or look burned,
on the circuit board of the SATA harddrive, then you may want to stop here.

The 'cure' may be more costly, than the information you have saved on this external harddrive.

But,
IF, the circuit board of the SATA harddrive looked good to me, I would risk a small amount of money, to see if I could get the harddrive to work again.
Again, just my personal preference, and not direct advise that this is what you should do.

I would buy an External Enclosure, and install the SATA harddrive in it. The External Enclosure also has a circuit board inside, and uses a USB cable to connect to the computer, just like the External harddrive that you have now.

Average cost for a decent external enclosure for a SATA harddrive is around $30 USD.

Here is an example, (Not an advertisement for the external enclosure manufacturer, or said website),

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2145406&CatId=2780

The external enclosures come with info about how to open the enclosure, and install the SATA harddrive.

Should you have gotten this far, thank you for your time.

I have left my hard drive off for 12 hours as adviced, but on turning it on again the problem is still the same. The drive is trying to boot up over and over again.


My solution will be multipart, and lengthy. So if you're a coffee drinker, I suggest you make yourself a fresh pot

Reasoning? I'm going to explain a little bit about the hardware makeup of an external harddrive, and multiple solutions that in the hopes of one of them, may cure your problem.
I'm trying to arm you with as much information as I can, so you can use deductive reasoning, and take the best approach for You.

General symptoms that affect an external harddrive,

1.Bad USB cable. Although it is unlikely, USB cables can go bad.

2.Power supply.
To solve this problem, you need another power supply just like the one you have, for a test. ( Not exactly laying around. I have a work around for that, which I will detail later)

3.Controller failed.
Inside that external enclosure, (The metal, or plastic box of the external harddrive), is an ordinary harddrive such as used in a desktop, or laptop computer.

Yours has a Desktop size harddrive in it. (They measure 3 and a half inches across in width. 3.5"
Laptop HD's measure 2.5")

Harddrives are IDE, or SATA. All harddrives have been going to SATA for quite some time.
Yours is a SATA harddrive.

Inside the external case is an Interface, connected on a Controller Board.

Harddrives use metal round pins that are built on the harddrive itself. These in turn plug into an Interface, or also can be referred to as a Socket.

With an external harddrive, the harddrive itself may plug right into the Interface, (Socket. The metal pins of the harddrive plug into the Interface socket holes), or the Interface plugs onto the harddrive, and cables lead from it to a small PCB in the external harddrive enclosure. (Case)

The metal pins transfer data (Information) back and forth. (Signal pins)
Power for the harddrive is also transmuted through these pins.
Just like plugging in a lamp to a receptacle.

The Controller Board is a PCB. Printed Circuit Board.
This is connected to the bottom of the harddrive. It controls the mechanism inside the harddrive.

This is a link to Howstuffworks>Computer Channel>
Computer Hardware>Hard Drives and Disks>How Harddrives Work,

http://computer.howstuffworks.com/hard-disk.htm

When you arrive at Page 5 you'll see the Controller Board. (Their term is Electronics Board)
The Controller Board can be safely removed from the harddrive, and not ruin the harddrive.

You cannot open a harddrive case itself, where the Platters and Arms reside, Unless you have the proper environment.
('Clean Room'. A 99.9% dust free room that would make NASA jealous! This type of room is where a typical harddrive is assembled)

If you use an ESD wrist s-trap and connect it to a good ground source, plus work on a table, you can safely remove, and replace the Controller Board. (No magnetism Anywhere near! NO speakers!)
An average ESD (Electro Static Discharge) wrist s-trap is about $6.

This link shows the connector pins I have been referring to,

http://en.wikipedia.org/wiki/File:Hdd.jpg

(You can click on the photo to enlarge it)

At the bottom of the photo is the back of the harddrive. All the way to the right are 4 pins. These are not recommended to be used on a SATA harddrive, but are for power to the drive.

All the way to the left, is a connection which has 15 pins for the Power connector, and to the right of it are 7 pins for the Data connector.
(It's in the upside down U shaped opening. There is a rectangular wide opening all the way to the left, then a narrow rectangular opening, then the upside down U shaped opening)

4.Harddrive failure. The mechanism inside the harddrive itself has failed. These are mechanical components, as you can see in the Howstuffworks link. Average lifespan for a harddrive is 5 years. Depends on how much it's used.

Solutions:

A.If the harddrive is still under warranty, you can see if the manufacturer will replace it. HOWEVER, they do not guarantee anything that is stored on it. You will get another harddrive minus your information.

B.You can take it to a Data Recovery Specialist. Average price is $50 per hour on up. Average time is minimum 1 hour, and usually takes 3.
I could be mistaken, do research for your area.

C.
1.You could start with using another USB cable, and see if this is the problem.

No?
2.Then it's on to the power supply. This solution cures 2 possible problems. I didn't mention, that sometimes the small PCB board in the external case also goes bad. Most of the time, according to hits on the internet, this is a major problem with a LaCie external hardrive.

The small Printed Circuit Board inside their external harddrive case, (Enclosure), goes bad.

Solution is to buy an external enclosure for a 3.5" SATA harddrive. Take the harddrive out of the LaCie external enclosure, and install it in this one.

Check computer hardware websites on the internet. (Examples of two are Tigerdirect, and Newegg) Look for Harddrive Enclosure. Then 3.5, then SATA.
Average price for a decent one is $20.

3.If this doesn't cure it it may be the Printed Circuit Board on the bottom of the harddrive. If your data warrants saving, then you may want to buy the SAME style of harddrive, borrow it's PCB, and get your information off of your old harddrive. More cost I grant you, but cheaper than a Recovery Specialist. You aren't buying another LaCie external harddrive, you are buying just the saqme SATA harddrive used inside.

Past this, the harddrive mechanism itself has quit. Only a very competent, reliable, Recovery Specialist can recover your data, if possible.

Malfunctioning WD passport that windows doesn't detect.


Inside the case is a regular laptop size harddrive.
Laptop harddrives are 2.5 inches across. (2-1/2 inches. Desktop harddrives are 3.5 inches)

I would suggest the external enclosure the harddrive is in, is defunct.
I would suggest buying a new external enclosure, and putting this harddrive in it. Then just plug the USB cable in, (As you did before), and download your data, to be ready to transfer.

You need an external enclosure that is Sata, and is for a 2.5 inch harddrive. These are relatively inexpensive.
Let me show you some examples:
