Hard drive clicks, fails to read but powers up. Approx 100GB of music files held and needs recovering. Laptop initially picks up drive on connecting to USB port but then drops out due to read failure.Drive...


Inside that plastic external case of the Hitachi XL 1000 external harddrive, is a regular desktop computer sized harddrive.

It is a SATA type of harddrive.
It is 3.5 inches across in Width. (3 and a half inches)
1 TB in size.

Looks similar to this example,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5589521&CatId=2459

On the back end of the Harddrive is where it's power cable, and data cable are attached.

Inside the case of the Hitachi also is a small circuit board. (PCB or Printed Circuit Board)
The SATA harddrive is connected to this small circuit board.

The small circuit board, or Interface PCB , is attached directly to the Harddrive.
Or cables (Wires) are used to connect it to the Harddrive.
The Interface PCB is connected to the computer, via the USB cable that is attached to the Interface PCB.

It is this small circuit board that usually goes bad.
(Unless the external harddrive was on, and dropped. Then the problem is the Harddrive)

There are two solutions;

One, buy an 3.5 SATA external enclosure, and use the Harddrive as an external harddrive again.

Two, install it as a Slave drive in a desktop computer, and retrieve all your information. Burn to disk/s, or flashdrive/s.

When using a SATA harddrive as a Slave drive, there are NO jumper pins to mess with.
DO NOT change any jumpers on the back of a SATA harddrive.
(These are for the factory)

This is an example of a 3.5 SATA external enclosure,

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

There are no guides to open a Hitachi XL 1000's case, to my knowledge.
It isn't something the manufacturer wants stated.

However opening the external enclosure (Case) isn't that tough. It falls under the same as this model,

http://www.youtube.com/watch?v=hQ_vjyvK28A

Here we see at 3:00 through 5:00, that the Harddrive is attached directly to the Interface PCB.
Just remove the Harddrive from the chassis, and unplug it from the Interface PCB.

For additional questions please post in a Comment.

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)

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.

Example of a 2.5 SATA external enclosure,

My hd with power but cannot detect by pc due to fall in the floor while using it. lots of important data and pics


Is this problem for an IOmega Prestige 500GB external harddrive?

While I wait for you to post in a Comment,

1) Inside that external harddrive's case, is a Harddrive just like what is used in a laptop computer.
The harddrive's case measures 2.5 inches across in width. (2 and a half inches)

The harddrive is a SATA harddrive. (Serial ATA)

At one end of the harddrive is a series of connector pins. These pins plug into a female connector, or receptacle.
The receptacle is called an Interface.

http://www.allpinouts.org/index.php/Serial_ATA_%28SATA,_Serial_Advanced_Technology_Attachment%29

The Interface will have connections for Data, (Information), and Power. (Socket holes that match the pins on the SATA harddrive)

In the link above the data, and power connections for the Iomega external harddrive, will probably be a combined unit. As shown in the 8th illustration down, in the above link.

The Interface can be soldered directly to a circuit board, (PCB, or Printed Circuit Board), or will be attached to the circuit board through wires.

Usually it is the circuit board that is the problem. Components burn out, or circuit traces on the circuit board are burned apart.
(Think of a circuit trace as being a very flat, thin copper wire)

There may be a situation where the harddrive itself has come loose from the Interface. Doesn't have to be very loose to make a bad connection, resulting in the external harddrive will not work.

My proposed solution:

Open the external harddrive's external enclosure, (Case), and see if you can see any readily apparent visual signs as stated above.

No visual signs that show you that you can just plug the Interface onto the harddrive, making a tight connection?
Or plug the harddrive into the Interface, if the Interface is soldered to the circuit board?
Or no obvious signs of blackened spots on the circuit traces?

It could be that one, or more I.C.'s are bad, and are not readily visible.
(I.C. = Integrated Circuit)

Weigh buying a used Iomega Prestige 500GB USB 2.0 harddrive, and use it's circuit board, and external enclosure, against what a professional recovery service will want to recover your data.
Not trying to be trite. Am asking you to weigh the costs.

One place that came up in a search just now, that is supposed to have used Iomega Prestige 500GB USB 2.0 external harddrives,

http://www.amazon.com/gp/offer-listing/B001D7REIK/ref=dp_olp_used?ie=UTF8&condition=used


How to open the external enclosure:

Remove the external harddrive from the stand. Remove labels for access to screws. The screws will probably be Torx screws. A star shaped recess in the screw head,

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

May be Philips head screws, but I'm betting on Torx. (Probably metric Torx also)
You should be able to find a cheap set of Torx screwdrivers at an auto parts store. Perhaps just the bits to use in a 1/4 inch nutdriver.

Once the screws are removed the internal parts slide out of one end, or the case comes apart in two halves, and the ends come off.
(Internal parts being the harddrive, and circuit board)

Not a very professional,approach, just for an added source of opening an external harddrive's case,

External Harddrive does not work


Hi:
Hitachi hard drive are junk they are poorly made, but here is an option the could by a bigger hard drive and install it in the External case they are all the same, first take out the old HD from the case and take it with you to the store and purchse the same connection type wether its IDE or Sata and install it in the case, the cases are universal and all most all 5-1/4 inch HD will fit in the case is does not have to be A Hitachi Brand any brand will fit, I recommend a Seagate HD.
