LaCie Compatibility Issues

08/30/10: Buyer beware! LaCie network drives have a severe Windows compatibility issue being non-functional with Windows Backup Utility.


This is a major LaCie hard drive problem (for anybody serious about their data), but LaCie refuses to show any sign of wishing to fix it or even acknowledge the problem exists.

Shown below is an archived month long service ticket, and you only need to scroll to the bottom and read the two final short posts in order to confirm that you want to stay away from these Drives.

Take it from me, LaCie's response after the one shown only got more insulting and obfuscating.

With Windows Backup Utility, on restoring file (backed up from separate LaCie Ethernet Disk) receive message: "Warning: The target file system does not support some [sic] the features of the original file system. Some data may not be restored as a result."

Following through with restore causes restored file to display "Attributes" toggle on the first page as earlier versions of Windows file system.

Needed to download newest version of LaCie Network Assistant to get drive running, but did not reformat drive.

Drive is not found in Windows Device Manager due is network drive LAN attached.

Good morning Bob,
My name is Patrick, and I will be happy to help you with your LaCie product. First of all, I would like to thank you for choosing LaCie, and we appreciate your patience and trust in our products.

Would you please click here to get the last version of LaCie Network Assistant.

Thanks, and please let me know your results.

If this thread gets posted somewhere, please remove my e-mail address.

Otherwise, click where?

The only clickable element I see is the "RATE" button, which we are far from needing.

I already downloaded the most recent version of LaCie Network Assistant in order to get the drive up and running in the first place.

I looked it up again after submitting this issue while I was double checking to make sure I had current software.

It appears the bottom line is that the refurbished (by LaCie) 2T LaCie Quadra 2D Network drive's file system does not present itself to Windows Backup in the same manner as my 1T LaCie Ethernet Disk which I was hoping to replace.

In any case, if the following file (found on my own) is not the one you are referring to, please redirect me.

Hello Bob,


Thanks a lot for your patience so far, as I can see you need to contact Microsoft tech support regarding that error message.


Also you download the latest version of the LaCie network assistant from HERE.


Please Bob, do not hesitate to contact us for any further help.

Thank you for the link, LaCie Network Assistant 1.4.3 Win is in fact the version I am already running.

Are you telling me that this is not a known issue, and that the drive has been tested to be fully compatible with Windows XP Pro SP3, plus the file structure should be fully compatible with what is coming off my LaCie Ethernet Disk, and that I should be able to replace my LaCie Ethernet Disk with this refurbished LaCie Quadra 2D Network drive?

And the only problem is with my operating system and/or Microsoft backup utility?

Hello Bob,


Mainly the drive is compatible with Windows Xp, also I suggested that you contact Microsoft because it has something to do with the backup utility.


Thanks a lot,

Hi Tec : ) <p>

Apparently the issue is not resolvable. </p><p>

Since your last reply, I purchased a new 2TB LaCie Network Space 2 KUA hoping that it would be fully compatible with my existing 1T LaCie Ethernet Disk, in the same manner as are my 4 LaCie 1TB Hard Disk Design by Neil Poulton USB, FW400 & eSATA drives (connected to my laptop via FW400 and working correctly), but the new drive was also incompatible with the Windows XP Pro file system (and my 1T LaCie Ethernet Disk) in the exact same way as the 2T LaCie Quadra 2D Network drive--which was the subject of this support ticket. </p><p>

I sent the new unit back to LaCie for a refund, but I am stuck with the Quadra due to the fact I already spent three days getting a 1/2 terabyte backup file onto it, before finding out about the incompatibility issue. </p><p>

I will hold onto the Quadra and use it as a temporary off-load point for future major backups while waiting for the happy day when other LaCie drives which are quieter, lighter, and with a smaller footprint than my 1T LaCie Ethernet Disk become available. </p><p>

So you see, I cannot in good conscience click the (Close) toggle. </p><p>

BTW: In an attempt to get this file to break paragraphs correctly after uploading to the LaCie service ticket page, I am embedding some html tags and hope they don't cause a problem. </p><p />

Hi Tec : )

Well, the html tags didn't help, but don't worry about auto closing this ticket.

I have kept very precise copies of every post, so I can publish them elsewhere.

Hello Bob,


Thanks for your response, mainly the drive is compatible with your Windows XP.

To use the Windows Client Backup and Recovery program included with the Ethernet Disk, an update is required.


CLICK HERE to download the new Vista version of the program.

A program called the "iSCSI initiator" is also required, and may not be installed on all systems. This is available for Vista from Microsoft's website.

NOTE: This software does not work on 64 bit versions of Windows Vista.


Please Bob, let me know the results.

No thank you.

I prefer using the Windows XP Pro native Backup Utility included with the Windows XP Pro operating system itself, not Vista, not 64 bit, no SCSI drives involved, just standard old timey, run of the mill, out of the box Windows XP Pro, and of course not just merely "Windows XP" (as you mention as mainly compatible) but tried and true stock Windows XP Pro.

My false logic in this matter is in believing that Windows' own backup program will outlast all contenders to the throne, and the 1/2 terabyte of data (for which I have built and maintained continuity over 25 years) will still be intact 30 years from now.

In any case, I have already wasted more time on this than it is worth, plus I stopped acting as a Beta Tester in any given situation more than a dozen years ago, but thanks for trying.

All LaCie needs to do is get the LaCie Poulton Network drives to work exactly like the LaCie Ethernet drives.

Should be simple.

Also, somebody at LaCie might like to flatly admit that a compatibility issue exists--if the hoops and hurdles you have suggested for me to navigate have not already done a fine enough job by their own accord of implicitly admitting the fact of incompatibility.

At that time, I will click the toggle for: "My question has been answered. (Close)," but not before.

Hello Bob,


Thanks for your patience so far, you can use one of our backup assistant software, but the drive should work flawlessly with Windows XP Pro native Backup Utility.


If you are facing any difficulties with it I would suggest that you contact Microsoft tech support.


Thanks for your patience Bob, and please accept my apology for the inconvenience caused by this.


Thanks a lot,

Same bad behavior exhibited from two (2) other computers with two (2) separate backups of which both are files coming from LaCie Ethernet Disk trying to be restored to LaCie Quadra D2 Network Drive.
