My iMac does not recognize the Lacie 1tb big disk extreme external hard drive. No icon appears.

the first step will be to verify your power supply. When it is plugged to the wall power outlet, it should be silent (no hissing or high pitch noise) and the green light should be on on the power supply.. If it is not the case, replacing it might solve your problems.
Second step is to verify if it is an interface problem. Try using a different port on the drive.
If no success, start Disk Utility and look to the left if you have any mention of a drive of 1TB. If you do, the partition of your drive might be corrupted. You can try running First Aid from Disk utility if its available, else you will need to try a partition repair software or a Data recovery program.
There are a few available that you can get a free copy to see if the data is available before you buy.

Help is it possibol to upgrade lacie big disk extreme 500gb to 1tb or 2tb. thanks. FC

Maybe. If the current disk-drive has an IDE interface, then your 500GB disk-drive already is the largest IDE disk-drive ever produced. Or, if the current disk-drive has a SATA interface, then the sky (or the thickness of your wallet) is the limit.

I would like to reformat my lacie to 100% (1TB) windows. at this moment its divided in two and the windows part is only 29GB how to i reinstall? reformat? just make everything come back to how it was the...

If you boot the computer from a windows CD/DVD in he first stages of installation it will look for all partitions on your hard disks. When it finds your lacie highlight the partition and use the option to delete partition. Repeat this for any other partitions you wish to remove. Now you can use the format option and install windows as normal. Cheers from Scott please dont forget to vote

Acronis partitioned LaCie d2 Quadra 1TB. Tried to eliminate the partition and ended up with 100% unallocated space. How can I repair this problem? Thanks, Tom

Go to Start > Control Panel >Administrative Tools > Computer Management > Storage > Disk Management
Choose your LaCie drive. Right click on it, and choose mark the partition as active.

This should give you one partition of 1TB in size.

Window and OSX - fun and joy.
Since you formatted a 1TB drive and it works fine in Windows, I have to concluded the the drive was formatted NTFS.
Here is the issue in a nutshell, OSX supports reading NTFS but have very limited write cababilities.
If you want both Windows and OSX to have full access to an external drive you should format it FAT32. The only issue then is that under normal conditions a FAT32 drive has a maximum size of 32GB.
I would partition the drive to have 1 or more FAT32 partitions and then have the rest of the drive NTFS.

Is the OSX version correct or should it be 10.3. If it is actually 1.3 it would mean you have the OSX Server edition that originally came out in 1999 and it may not have very good USB support - version 1.2 would only support 1 USB device.

LaCie d2 Extreme Hard Drive

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.
