LaCie d2 Extreme Hard Drive

I am plugging my d2 in for the first time, and it appears as if it is working properly in device manager, but does not show up in My Computer, and thereby is inaccessible. What do I do?

    I have been using my LaCie 250 gb hard drive for back up on my pc with sync back up software.  Now I connect it to my Apple to back up that and I get a message read only so I cannot write any files to it.  Why is that?  Can I only use it on PC not Apple?

It could be that the drive is not formatted or initialized! Try this, right click on My Computer then click on Manage. Go to Disk management in the left pane. You should see all your disks that are installed in the right pane, it should show you their status. Actually if it is a new unformatted disk it should bring up the "Initialize Disk" window. If it does, follow the steps. If not look for a disk that is fully black (black means unallocated)then right click on the disk and Create a partition. The create partition wizard allows you to format the disk afterwards. If you plan to use the disk on some windows 98/ME machines you need to create a FAT32 Partition(FAT32 partition can't be larger than 20GB(20480MB) if not just format it NTFS(performs better and more reliable). Hopes this helps.

How to format the LaCie 500GB d2 Quadra for Windows XP??

This way it should work...
Connect your drive to the computer...
Go to: Start > Control Panel > Administrative Tools > Computer management.
A new window will appear...
Select Storage > Disk management on the left of the window.
Now you will see the different drives that are connected or part of your system.
One of the drives listed there is your LaCie, i think you'll recognize it by name...
Right-click on it, and select 'format'
In the new window, select the new volume label (as you like it), the file system (use NTFS), and set allocation unit size to default.
Make sure 'Perform a quick format' is not checked...

Then click OK. Your drive will be formatted now... Don't interrupt the process

Lacie d2 external drive

I support the comments of (fire sine) I have the d2 120gb Lacie and it was down for two years.  I took it to my apple guys and they said that I needed to go to a data recovery service which would cost a gang of money.  Come to find out, when I decided to update my internal hard drive on my Mac Pro, I had to buy a SATA, IDE, USB 2.0 adapter to back up the internal and transfer to the new internal. Long story short, something said, Hey try and open the Lacie and bypass the board in the enclosure and connect directly to the Western Digital drive inside.  AND WHALA! I got my info, so all I need is a new enclosure.
