Question about LaCie Big Disk (LAC300966U) 1024 GB Hard Drive

LaCie won't start

Dear experts,
I've been working with my LaCie Big Disk for about a year without any problems. I brought it over to a friend to show him some things, I set it up and it worked perfectly. When I came back home it wouldn't start. The blue power button flashes but no sound or vibrations from the disks. 
Please help me solve this problem. It is very urgent. 
All the best,

Before you read this solution!!!! READ 3 IMPORTANT NOTES!
1. If you dropped it and it's clicking continuously sorry but it's probably trashed... When you call up Lacie about the Warranty DO NOT TELL THEM YOU DROPPED IT they will void out your warranty and you will end up having to buy another HD adding insult to injury when you lost your files as well... just say it's not working... It's not lying It's just called sticking it to corporate glutons who from whispers I've heard sell refurbished Lacie drives as new ones to ignorant customers
2. I've been doing some research and certain programs like TweakUI a program that Microsoft installs which can be found in your control panel does conflict with the Lacie HD
3.This problem occurs whether or not you use a firewire or usb or sata so if you don't have one of these sockets in your computer
don't buy extra equipment

The Meat:
Aaaaaaaaaaaaaaaaaaactually Windows regardless of XP or Vista tends to screw up when it comes to Lacie drives...
This is how you fix it for sure:
go to control panel
administrative tools
computer management console
open up the disk management section
in there....
you'll see your C: drive or what other drives you may have already set up
you'll see one drive that doesn't have anything assigned to it no drive letter or anything 95% of the time that will probably be your lacie drive fresh out the box
Only thing you gotta do now is enable that drive by right clicking on the grey box next to it where it should say disk and for the sake of simplicity let's say it says Disk 1 or Disk 2 whatever
Enable it then partition it using NTFS if you're only going to use it on windows and FAT32 if you want to be able to use it on both MAC and PC

If you already have things on your hard drive from before and it just started acting up:

Try doing these 3 things:
First Lacie said that the drives can be tempermental when you don't shut them down right... so you would have to
disconnect all wires
connect power cord only and plug it in
turn it on wait a couple of secs.
connect usb cable to drive then to computer
that's one way of fixing it

if that doesn't work

you can try going to control panel> system> hardware> device manager

in there try and see if you have anything with a yellow question mark or exclamation point or a red X next to a USB controller or
Composite device or to Mass Storage Device under USB peripherals

If it has either of those just right click on the device and click update driver

If not right click mass storage device> uninstall
right click composite device> uninstall
right click on icon in lower left hand corner to remove device safely
choose the drive > remove safely> use turn off switch to turn it off...
Now turn it back on and it should reinstall itself

If that still doesn't work there's a couple of tutorials on how to recover files from faulty Lacie drives you can google that and it should be able to help you out for the most part...
This may involve opening up the casing and removing the hard drive not the internals and connecting it to your desktop directly
worst case scenario you may have to repartition/format your drive and it should be back to normal at this point your going to have to call

Hi IB4G2008 and thank you for your time and help!

It doesn't sound like anything is loose inside. The disk was also very well protected when I transported it.
I've taken out the connections and put them back in again a few times it didn't help.

Thank you for your help.

Restore files

You can have the data removed by a file recovery business, it is costly. They remove the stoarge media and read it directly using special equipment. Unless the hard drive works (you can read it with your computer) that is your only choice

Try swapping usb cables if possible. You can also try swapping enclosures but this will void your warranty.

See if it shows up in Windows Disk Management if so then you may have just lost the partition you can try to recover lost partitions with Testdisk its free

It may be your best bet is to contact Lacie support.

I have a 1TB LaCie 2Big Quadra. It has 2 500GB and runs on RAID 1. I replaced both 500 GB LaCie drives with 1.5 TB LaCie drives, but my computer only recognizes the original 500 GB. I formatted both...

I have the same problem too on my 2big form lacie . If I use 2x 1,5 tera disk in "fast mode" or in "big mode" my disk manager only shows 746 gigs available (it should be at least 2,5 terra).
If I use "safe mode" so my system can see 1,3 tera available, wich is normal for a raid mirror configuration.
I hope to find a solution quickly.

Hope this helps??!!
Posted Oct 13, 2006 - It's not the drives that fail, it's the power supplies... They fry after about 3 months-1.5 years. LaCie sells replacements for about $16-$20, dpeneding on the model. We have over 20 of these drives, and here's how you know: the drive spins up, then down - it tries to mount, data transfer will freeze, etc. Just put another power supply on it, and 9 times out of 10, it's fine. Of course, any drive can fry on you, but these have proven to be extremely reliable under some of the hardest use imaginable.

Trouble seeing my lacie drive possible mounting issue

Not sure if this is the exact same issue, but I couldn't get the drive to mount with different connections, etc. The problem turned out to be the power adapter. If you've got the same kind of adapter on another drive, switch it out and see if your drive shows up. Good luck.

Lacie big disk 2.0 usb

For anyone with a Big Disk drive that doesn't get recognised by Windows and gets a TUSB 6250 message in Device Manager, the cause is very likely to be the power supply. Although the drive will be powered up, it is not spinning at the correct speed. I tried all of LaCie's technical support suggestions, some of which are outlined above and none worked. They finally suggested getting a new power supply. This solved the problem (Wattac, £22). This problem has affected a lot of LaCie Big Disk owners...
