Maddog External Harddrive Enclosure not recognized by computer

I have a Maddog Multimedia USB2.0 external harddrive enclosure. It usd to work at one point, but is not anymore. When I plug it in to the computer, I get the sound effect of my computer registering that it is there. It is not listed as a storage devide such as G:\\. I cannot get access to the files. Should I try to download a new driver. I have not done that yet.

    I too have the same problem. Put in a 40g hd that worked at first and then quit. Have also put in a 30g hd to try and get it to work but to no avail. Changed jumper settings to set as slave but did not work.

I realize the above questions are almost a year old but someone may try to research this at a later time so I thought I'd throw in my two cents.I have the Maddog Multimedia USB2.0/eSATA external harddrive enclosure which I connected to my computer last night but could only get it to appear as a "USB device" to my computer (in control Panel-System-Device Manager). It would not appear under Computer management so I could not force a drive letter on it and it would not appear in Windows Explorer. I removed the Seagate 1TB drive from the enclosure and connected it to my computer without an enclosure using an IDE/SATA interface I bought for another purpose. The drive worked fine. Today I took another look at the situation - I was going to try another drive in the MadDog enclosure to see if that worked but instead decided to reinstall the Seagate 1TB into the enclosure and try again. Same result until...I started reading through the comments above which forced me to look closer at the back of the device. That's when I remembered the device has a physical switch in the back for eSATA vs USB. I hadn't used this device in many months and my eSATA card has never worked on external drives so I forgot about it. sure enough I powered down the drive, flipped the switch to USB an powered up again. Problem solved. I am not new to this stuff but even experienced users can make a silly mistake. I only hope your issues are as easily solved.

I had the same problem. My Fix was to use BOTH the USB Data Cable and the USB-to-Power cable. When I first started using it, it worked the USB alone. After a couple of days, however, it failed to power up. The Blue MadDog lable on the front wouldn;t light up, and when holding the unit to my ear, the spindle was not rotating. After finding a USB-to-power cable, which came with the unit, and hooking it up along with the data cable, the unit functioned fine. What sucks is that this uses up 2 USB ports. I have seen some USB cords with two leads that will branch POWER ONLY to one of them but then you end up with low performance and a rats nest of cables.

Trying to find the operators manual for prestige desktop hard drive super speed usb 3.0 ,2 tb


The general directions is to plug the USB cable from the IOmega Prestige into any available (Open) USB port.

To open, (Access) the contents on the harddrive, double-click on the drive letter that corresponds with the IOmega.

In WinXP left-click on Start, then on My Computer.
In Win Vista and Win7 left-click on the Windows logo button, then on Computer.

You will see there are different drive letters;

Drive A: is reserved for a Floppy Drive. Older computers
Drive C: is for the Harddrive. (Hard Disk)
Drive D: is reserved for a recovery drive, or an optical drive (CD/DVD drive)
Drive E: is reserved for an optical drive, usually.

Drive letters beyond these are usually under the heading, Devices with Removable Storage

One of these drive letters should correspond with the IOmega.

Suggest, IOmega not plugged in, go to My Computer, or Computer, and look at the devices connected to the various drive letters.

Now plug the IOmega in, and see if it shows up next to a drive letter.
(Give the computer BIOS a few seconds)

Where there was NO device shown BEFORE, there should now be a device shown.
{No device shown before, but now there is. May not state IOmega, just external storage, or similar}

DOUBLE-click on the device shown.

For example:

I have drive letters C: D: E: F: G: H: I: J: and K:

Drive letter C: is for my harddrive.
Drive letter D: is for a recovery drive. (Partition in harddrive reserved for recovery)
Drive letter E: is for an optical drive (CD/DVD drive)

Drive letters F through K are reserved for an external storage device.
Whether it be an external harddrive, or flashdrive, or what have you.

IF you find the drive letter that corresponds with the IOmega DOUBLE-click right on it.
If nothing happens, or if there is no device shown when the IOmega is plugged in, there is a problem with the IOmega.

Hard to believe IOmega is still having problems with their external harddrives.

In the past they were having problems with a small circuit board located inside the IOmega's case.

[ A circuit board is a PCB.
Printed Circuit Board

For example a computer mouse has a small PCB in it,

http://en.wikipedia.org/wiki/File:Mouse_printed_circuit_board_both_sides_IMG_0959a.JPG ]

The small circuit board is an Interface Board.

It connects the harddrive inside the IOmega's plastic case, to a USB cable, and this allows the harddrive inside to be plugged into a USB port on a computer.

As mentioned inside the plastic outer case (External enclosure) of the IOmega is a harddrive.
(Hard Disk drive; proper speak)

Harddrives are measure across their Width. There are two current types used;
A laptop size harddrive, and a desktop size harddrive.

A Laptop size harddrive is 2.5 inches across in width. (2 and a half inches, or 6.4cm)
A Desktop size harddrive is 3.5 inches across in width. (Or 8.9cm)

There are two technologies used;
IDE (PATA) or SATA

I'm sure the harddrive inside susanbrenton is a SATA unit.
I BELIEVE, it is a laptop size harddrive (2.5)

Point?

If there is data (Information) on the IOmega that you must have, you may wish to buy an inexpensive external enclosure, remove the harddrive from the IOmega, and install it into the external enclosure.

The external enclosure has a plastic case (Enclosure), and a small circuit board inside. It has a USB cable, or connector, just like the IOmega does.

Once you install the IOmega harddrive inside the case, the case is closed, and it's USB cable is plugged into a computer.
(Just like the IOmega. You are just replacing the small circuit board essentially)

Once you have the IOmega's case open, and can view the internal harddrive, measure the width of the harddrive.
Buy the appropriate external enclosure.

This is one example of an external enclosure for a 2.5 SATA harddrive,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3195233&CatId=2783

This is one example of a external enclosure for a 3.5 SATA harddrive,

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

Basic instructions on how to open an IOmega Prestige external enclosure (Case):

1) There are two Philips head screws on the Back of the case.
These are removed.
Once removed a the oblong panel on the end comes off.

2) You can now see the harddrive inside. Pull from the Front, and remove the harddrive out of the case.

3) The harddrive is attached with screws to a metal carrier. (Bracket, essentially)
Remove the screws, remove the harddrive.

Basic example, the harddrive will look like this,

My WD Book was spinning and clicking constantly, so i unplugged the USB and the power source from my laptop. After plugging back in, it is no longer recognized on My Computer -- I've rebooted 2x. My...


Let's hope the spinning and clicking was caused by a bad circuit board in the WD Book, and not the Harddrive inside it.

To explain;
Inside the plastic external enclosure (Case) of the WD MyBook is an ordinary harddrive as used in a laptop, or desktop computer.

There is a small circuit board inside the case, that the harddrive plugs into. (Or there are wires from the small circuit board, to the harddrive)

The other end of the circuit board, has a USB cable attached to it.
The circuit board is an Interface Board.

It is this small interface circuit board that USUALLY goes out.
Harddrives are pretty tough, but they are a mechanical device, and are rated in hours of usage. They can fail.

What I would suggest is to buy an economical external enclosure.
Has the circuit board, USB cable, and everything needed, just needs the Harddrive.

Installing is easy. There are instructions included.

Now we come to the technical portion.
What size harddrive is it, and what technology does it use?

Size:
1) There are two sizes of Harddrives. They are measured across the Width.

A 2.5 inch harddrive is a laptop size harddrive.
(2 and a half inches across in width)

A 3.5 inch harddrive is a desktop size harddrive.

Once you open the WD MyBook case, and measure, you will know.
Pretty easy.
Technology:
Looking at the harddrives label, will tell you if it is an IDE (PATA) model, or a SATA model.

If no nomenclature is readily apparent looking at the label, there will be a model number on the label.
Put the model number in your search bar.

Example:
WD2500BEVT

http://www.newegg.com/Product/Product.aspx?Item=N82E16822136387

250GB SATA harddrive. Also is a laptop size harddrive.
(2.5)

If you cannot find the information, just post the Model Number in a Comment, and I'll find out.

Example of a 2.5 SATA external enclosure,

Example of a 3.5 SATA external enclosure,

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

Example of a 2.5 IDE (PATA) external enclosure,

Example of a 3.5 IDE (PATA) enclosure,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1337265&CatId=2779

The information on how to open a WD MyBook case, is not something the external harddrive manufacturer states.
For this we'll have to rely on videos that are made,

WD 500G HDD suddenly un-readable; changed name to local disk, says I need to format in order to use it. I have tons of important stuff on there.


Could you confirm if the problem with the drive not being recognized is a problem with the USB cable? I have a 250GB passport and it worked fine with my XP. Once I decided to reformat it to NTFS and tried to do so by plugging into my new windows7 laptop the problems started.

My lacie drive fell off desktop and is not recognized as readable by my Mac. What chance do I have of recovering the data?


Inside that LaCie external harddrive's enclosure is a regular SATA harddrive.
The kind that fits in a desktop computer (3.5 inches in width), or laptop. (2.5 inches across in width)

Open the external enclosure (Case) of the LaCie, remove the harddrive, and install it into a suitable external enclosure.
(Laptop size, or desktop size)

The external enclosure has a USB cable also. Just plug it into any available USB port on your desktop computer.

Do I know for a fact that the harddrive is okay, and this will fix the problem?
No sir/maam I do not.

But IMHO this is the first diagnostic method to use.

IF the harddrive is a desktop sized harddrive, it could be installed in your desktop computer as a Slave drive.
However the above method is so much easier, and it allows your harddrive to be an external harddrive once more.

Inside the external enclosure of the LaCie external harddrive, is a small circuit board that the Harddrive plugs into.
It is this small circuit board that receives the damage in most cases.

If the problem is the Harddrive itself, a professional data recovery shop will;

A) Try a new, or good used harddrive circuit board.
Check to see if the harddrive's circuit board received the damage.

B) If the circuit board proves to be good then the next step is to remove the Platters inside.
The room used is a Clean Room.
A room that is 99.9 percent dust free. (In most cases)

The Platters are installed into the case of a compatible harddrive, that has the Platters removed.
Then as much information as possible is copied off.

There are other methods data recovery specialists use also.

[A Harddrive is built in a Clean Room. 99.9 percent dust free. The technicians wear a Clean Suit, that resembles what a doctor would wear in an operating room.
They enter the work area after going through a corridor, fitted with air jets at various levels.

If a harddrive is opened up in a room that is not a Clean Room, the harddrive's 'life expectency' drops to a day, or a few hours. The dust 'kills' them ]

Can not get computer to recognize hard drive any more?


You could try using another USB port on your computer. Perhaps that USB port you have the IOmega external harddrive plugged into is bad.

More than likely not, though.

The problem is usually inside the IOmega's case. (External enclosure)

Inside that IOmega external harddrive's case is a regular harddrive as used in a desktop, or laptop computer.
To explain;

Harddrives are physically rated in width, as well as type, and size.
A laptop harddrive is 2.5 inches across in width. (2 and a half inches)
A desktop harddrive is 3.5 inches.

The larger desktop harddrives are usually used in external harddrives that are 500GB, and larger.
(Not always the case when it comes to the 500GB size)

Harddrives have two technologies, or types.
IDE (PATA) or SATA.

You didn't state the Model Number so I can't even hazard a guess at this point.

The harddrive inside the case plugs into an Interface.
The Interface may be separate, and connected via a cable to a small circuit board, or the Interface may be soldered directly to the small circuit board.

It is this Interface, and circuit board which go bad.
The solution is to remove the harddrive inside, purchase an inexpensive external enclosure, and install the harddrive into it.

The external enclosure has a USB cable just like the IOmega external harddrive did.

As stated the harddrive inside is just a normal harddrive. Made by a harddrive manufacturer.
Could be a Western Digital, or Seagate, or Hitachi, or Maxtor, or Fujitsu, or IBM, just to name a few.
(Seagate bought out Maxtor)

On the harddrive will be a decal with it's specifications.
You will also be able to physically measure the width.

This external hookup will support harddrives that are 2.5, or 3.5 inches in width, (And 5.25), plus will support both IDE (PATA) or SATA harddrives,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7220658&CatId=3770

This external enclosure is for a desktop sized harddrive, 3.5 inches, and will support either IDE (PATA) or SATA harddrives,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1951866&CatId=2780

This external enclosure example is for laptop sized harddrives, 2.5 inches, and will support either IDE, (PATA), or SATA harddrives,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7041055&CatId=2783

Just one example of how to disassemble an IOmega Select Portable harddrive,

http://www.youtube.com/watch?v=NvUvz5Qb4vw

Other styles are listed in the Suggestions column down on the right.
Not a good source for information on disassembling an IOmega external harddrive, but there is very little info available.

(It isn't that tough for any external harddrive enclosure. The screws are usually hidden under labels, and the case pops apart in two halves. Just a little different design here, and there)

My Lacie external hard drive used to turn on when the computer using XP was turned on. It has stopped doing this. Any suggestions to solve this?


if your computer came with a motherboard disc the drivers could be on it
click start control panel administrive tools ,computer management ,device manager look through all of your devices if you see a yellow question mark?or exclamation mark ! or red x
right click to reinstall drivers or
if you can see your usb but its not working
ports(com&lpt)right click update driver
just replace the cable of the hard disk, when you plugged the external disk drive you got that windows could recognize the USB device change the cable everything should work fine again, sometimes the wires inside the cable will be damaged due to bending or stretching or placing heavy equipment upon the cable,
check the USB leads that attach to the motherboard usually red-white-green-black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems hope this helps

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),

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,
http://www.tigerdirect.com/applications/category/category_slc.asp?CatId=2780&name=3.5-eSATA-enclosure&Nav=|c:2778|&Sort=0&Recs=10
(From $15 to $35, is a good range for a decent external enclosure)

Maxtor 3200


Seagate troubleshooting Error Code 10, states that drive has failed. (Seagate bought out Maxtor)

Before you resign yourself to everything is lost on this harddrive, how about trying one more thing?

How about putting the harddrive inside in a new external enclosure, and see if it works? I suggest that perhaps the external enclosure it's in, is bad.
The harddrive inside is a 3.5 inch harddrive. Same width as used by a desktop computer. It is a Sata harddrive.

Here's an example of a 3.5 inch Sata, external enclosure,
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3901268&CatId=2780
Just pop the external enclosure open that holds it now, take it out, and install it into an external enclosure like the example above. Plug in the USB cable.

Don't know if this applies to your particular Maxtor Personal Storage 3200, but when I went to search for the type of harddrive it uses just now, I ran into thsi, and thought I would pass it along. http://www.seagate.com/www/en-us/support/downloads/personal_storage/ps3200-sw)
