I had files on my laCie USB 2.0 now for some reason the files are not shosing up.

Remove the USB module from the LaCie Write Card and plug it into a free USB port on your computer. Your computer should assign a new drive letter to the USB module (such as D: or higher letter). In Windows use Windows Explorer (on a Mac use File Manager) and you will be able to copy files from your LaCie USB module to your computer.

Hello,
for the product that you selected for your question, it is impossible for the LaCie Network Assistant to see it because it is a Local drive (USB).
The LaCie Network Assistant only detects the Network LaCie drives.
Regards,

the problem is that your lacie drive operates using the NTFS (New Technology File System) under USB which is the standard file system of Windows. Apple mac is not interopable with native NTFS therefore you need to install a read-write NTFS file-system driver on your mac if you wish to use it via the USB connection.

an excellent free mac NTFS driver can be found here-
http://mac.softpedia.com/get/System-Utilities/NTFS-3G.shtml

download and install the software then restart your mac.

Have you checked the disk properties to see if the 400 GB of data is still showing. may be your data might be hidden foir some reason. can you give more details pls

Hello,

There are several possible reasons for this.

The most common is a short or failure in the Lacie enclosure caused by mixing up power/AC adapters. If your two Lacie drives are different models and you accidentally used the wrong adapter you may have damaged the circuitry.

The second possiblilty is that your power adapter or USB/Firewire cables could be damaged. Try switching USB/Firewire Cables First. If this fails to work then check if you have a smae sized adapter with the exact same Output Voltage and Amps on both adapters. Only if they are identical try switching adpaters from the working unit. If they are not proceed to the below solution.

Finally if the unit was dropped, bumped or unplugged while it was running it is quite possible that you may have damaged either the drive or the file structure on it, either of which would cause it to stop showing up.

Solution:

Try the cable swaps if able, if they work, replace the USB cable or replace the entire enclosure if the power adapter is the issue.

If neither works then you have either a failed hard drive or failed enclosure. Go to your local PC store (not a big box and yes PC, they tend to have more experience and parts to work with in this type of situation), have the techs there remove the drive from the Lacie enclosure and place it in a new enclosure for testing. They may not be able to see your files but they will be able to tell if the drive is working. If it is, buy the enclosure, then connect the drive back to your Mac. If it works you're done.

If the drive works but the Mac still doesn't recognize it(doesn't show up on the screen), then comment back and I will get you the link to a program you can use to retrieve the lost files.

If the drive simply fails to show up at the store in the new enclosure you will need the help of a pro to recover any important files. If that is the case reply with your location, Country, State and City and I will recomend an appropriate facility for you.

Hope this helps FixYa,

Chris

Here is the PDF Users Manual for the LaCie DVD+RW 301230U
external optical drive,

http://www.lacie.com/download/manual/portable_dvd_sh_en.pdf

(Give it at least 10 seconds to download)
Should the direct link above not work for you, you can download the Users Manual from here,

http://www.generalmanual.com/Disc-Burners/LaCie-301230U-Portable-DVD-RW.htm

Go down to the bottom of the page, and under the green -> Download Now <- heading, click on -> User Manual
The reason I posted the link to the User Manual, is that you can use a USB to USB cable for power. You plug one end of the USB cable, into an available USB port on your computer, and the other end, into the LaCie DVD+RW external optical drive. (You need two available USB ports on your computer. One for power, and one to connect the LaCie external optical drive. This USB cable, is called an Interface cable)

The USB end, that goes into your computer, (Laptop or Desktop computer), is the USB A style end. (Male) This is what it looks like,

The USB end, that plugs into the Lacie optical burner drive, is a USB Mini-B style end. (Male) It looks like this,
http://en.wikipedia.org/wiki/File:USB_types_2.jpg
It is the second one from the left side.

Where I'm at, we have Walmart stores. At Walmart they sell a USB adapter kit, made by Philips. This kit has a USB A to USB A cable, that both ends are Male. This cable is on a little retractable reel. The reel is about the size of a USA fifty cent piece. In the kit are five different styles of USB adapter ends. They just plug on that USB A to USB A style cable. (On the small reel) One of those adapter ends is a Mini-B USB male end. It has a Female USB A socket on one side, and a Male USB MIni-B end, on the other side. The kit sells for about $12 dollars.

Should you find that somehow, this USB power cable does not give enough power to your LaCie external optical burner drive, then here is LaCie.com, Products, Support & Downloads, and the Power Supply, for your LaCie DVD+RW 301230U external optical drive,

500Gb Lacie D2 Quadra with the same problem of flashing led and not mounting on the desktop (Mac G4 Mirror), traced to the power supply (57w) going down on power, both 12v and 5v supplies are available but the main power to run the drive drops to below an adequate output, hence the clicking and whirring evident from the drive with simultaneous flashing led.

Testing with another Lacie power supply (250Gb D2) this time a 34w unit got the drive up and running, however, and this is the reason for this post, this lower power PSU failed a week later whilst waiting for a warranty replacement from Lacie (5 weeks and still waiting for the new PSU from them. they have no stock)

Message for all Lacie D2 users, check the power supplies first, test with another Lacie PSU, do not run the drive on a lower rating (34w) PSU it will fry it and leave you with another failed power supply.

If you are in a tight spot use the temporary power supply to move your data to another drive and get the correct 57w power supply before running the drive again.

Don't do as I did assume any Lacie power supply will run any Lacie hard drive, they won't, fortunately I had a second back up, but am 2 drives down and no new PSU's available to buy anywhere.

Try and purchase another spare 57w power supply, something all D2 users should do for long term security, as these do not seem to be very reliable and getting warranty support from Lacie on these is currently impossible.

The lack of 57w power supplies from Lacie and its distributors across the world is surely a warning to be noted!!!!!!

Buyers beware!

Yes, it is. Try running a scandisk or other HD repair software you have on it.

The OS is hidden in memory, you can clear all files off the machine and it will still work.

The only requirements are the 4 folders:
Firmware
Movies
Music
Pictures

That's it!

New firmware can be found at www.lacie.com

I reccomend connecting you computer directly to your tv, depending on which mac you have. DVI or vga. I'm sure the manufacterer does as well. The files maybe in a codec your tv does not compute.
