Lacie 250GB External Hardive to be used between a PC and a MAC

If the external hard drive has been formatted on a PC in NTFS file format then the MAC cannot read data off this hard drive.
The FIX..
Connect the USB external hard drive to a Windows computer and copy your data off this hard drive to the computer.
Then format the external hard drive in FAT32 file format. (the MAC can read and write to data to and from a Windows PC)
Now copy the your data from the computer back onto the external hard drive.
Now you can connect the external hard drive to the MAC and download your data to the MAC.

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.

DEAR A FAT32 SYSTEM SUPPORTS A MAX VOLUME SIZE OF 32 GB PER PARTITION SO MUST DIVIDE IT INTO THAT LIMIT I THINK YOU SHOULD HAVE UNDER STOOD. ANY VOLUME MORE THAN 32 GB (VOLUME = SPACE) IN NOT SUPPORTED UNDER THIS SYSTEM

try to format it in other way like ntfs or fat32....

Thank you for asking your question with FixYa Support.

I am not sure what type of computer you have that your LaCie is connected to, but first and foremost, make sure the external hard drive has been properly formatted to work with the operating system your computer has.
For Windows computers: the LaCie should be formatted in either FAT32 or NTFS (recommended- more secure).

For Mac computers: the LaCie should be formatted in Mac OS Extended (Journaled) format.

If your LaCie is already formatted, then the best way to import your entire iTunes library from the internal hard drive of your computer into the LaCie, especially if you are unable to drag and drop the library into you LaCie, is to try a simple copy and pasting of the ENTIRE iTunes folder from its home on your computer to the LaCie hard drive.

You can also use the website I like to reference which provides some good alternatives to effectively migrating your iTunes Library from a PC or Mac to your external hard drive:

Here is that support link:

(also included in this article, are external hard drives)

For sake of space, I want you to review this article, because I not only agree with its content, it is exactly what I would explain to you as well in a more condensed, easy to follow fashion.

I hope I have helped guide you well on your question.

u need to install the driver

I think the migration assistant (in the utilities file in your application folder) can transfer files direct via USB.

solved: after referring to the userguide, I found that I formated my drive with a OS format, which can not be recognized by VISTA >> formated to FAT32 and now it works... 

Here try this link

simple just format it for PC first then it should work for both

if you format it for MAC first it will not work on the PC

simple

PC are horrible for accessing files

mac's are more user friendly
