How can I open a LaCie B350 External Hard Drive?

Inside the LaCie D2 250GB (300770) external harddrive's case, is a 250GB IDE (PATA) harddrive that is 3.5 inches across in width.

A desktop computer sized harddrive. (May be a Western Digital WD25000JB)

The harddrive plugs into a small circuit board, (Bridge board), and the circuit board has a USB port on it.

Using this Western Digital Passport for an example,

Scroll down to the second photo, and left-click on it. The case of the external harddrive is shown open.
Inside is a 2.5 inch laptop sized harddrive.
An aluminum tape strip covers the small circuit board, attached at the back of the harddrive.

The second photo down on this page, shows you the small interface circuit board, that the harddrive plugs into, with the aluminum tape removed.

(Another design has wires coming from the small circuit board, to an interface the harddrive plugs into )

It is this small circuit board that goes bad in a LaCie. QUITE common.

Solution?

Simple.
1) Obtain a 3.5 inch IDE external enclosure
2) Remove the 3.5 IDE harddrive from the LaCie's case.
3) Install the harddrive out of the LaCie into the external 3.5 IDE enclosure.

Hi... Problem with your external hard drive, pc don't recognize it...
it possible you have bad sector in your disk drive, or your usb cable is not responding.... the best way to find out open your box then take off our hard drive and install it into a pc and see if the hard drive work... or you box it self the controller inside our external box maybe damage,

Check your BIOS > StartUp sequence
Maybe the USB boot option has much higher priority that HDD boot. Try exchanging their priority and then reboot, with your external HD connected to pc.

just open your external HDD case, look for the connector (SATA or IDE), so buy new external harddisk case according the connector type.

Try connecting the Lacie to another computer, if it doesn't work then the hard disk may need to be formatted using Disk Manager. I suggest you format as a primary partition in FAT32.
If it doesn't work then it is possible that the hard drive in the Lacie has failed.
To test the hard drive, remove it and connect it to an USB hard drive adapter and connect it to a working computer's USB port. If it deosn't detect it as an external drive and you connot open folders and files then it is faulty.
You can install a new hard drive in the Lacie and then format in FAT32
There are companies that can recover data from faulty hard drives BUT it will cost you an arm and a leg for their services.

Sounds like the hard drive in the Lacie has fauled.

i use my external hard disk many times but now when i connect my lacie external H.D to PC it dose not recognized

Good News, Your data is probably still safe. Go to best buy or online and buy a new cheap external usb case for your harddrive. you can find them for about 7-25 bucks. Make sure you get the right one for the hard drive in your lacie. Take the hard drive out of the lacie case and put it in the cheap case and you will have your data back. I had this happen to me before. If you need help just ask me... Hope this helps you
