It is hard to buy replacement for the same enclosure, but there are many USB2.0/3.0 enclosures available on the market for 2.5 and 3.5 inch drives.
Make sure read reviews for issues and performance on those enclosures.

it can be easily fix by computer service center so you please take to the nearest servicing center

1. From what I read it may be the port drivers that are not installing for the USB port you have connected you hard drive to.
2. Check the manufacturers site for driver updates and hard drive requirements
3. It may be that the driver are not for the OS that you have or you may have to download them.
4. Try another cable ( USB)
5. Last it may be the internal electronics of the drive itself that may not be writing or reading the information sent by the pc to the port .
You may need a new case with new electronics ( hard drive main board).

Inside the plastic case of the Transcend StoreJet H2 1TB, is a small circuit board, and a laptop size harddrive.

The small circuit board is an Interface Board.
The harddrive plugs into it, or there are cables which come from the Interface Board, and plug into the harddrive.
The other end of the Interface Board has a USB cable attached to it.

Most of the time it is this small circuit board that fails. Very rarely does the harddrive fail.
(Unless the external harddrive was dropped)

I would suggest removing the harddrive from the Transcend, and putting it into an inexpensive external enclosure.

One example,

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,

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.

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)

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.

The usb port probably needs to be re-attached to the board, it would likely with have to be soldered.

You may also be able to remove the actual drive from the external enclosure, look online for info on that.

1.check the USB cord
2. the controller to the USB drive could faulty.
3.the usb port could be damaged / try another port.

***I hope this helps. Have a great day!***
