Replacing Drives Can I replace the internal drives with any ones bought from the local shops (any brand/size) or it has to be LaCie parts only. If the answer is any brand, how do I prepare and make it usable. Thanks

    Does the drives needs to be prepared (partitioned/formated) before using. I have bought two new 1.5tb SEATGATE drives and when installed, the LaCie boots, then the rear leds turn blue and the front one is red. The LaCie habgs not accessible via network and power off doesn't work.
    When putting back the old drives, everything works!!!! and clue what could be wrong.

    The LaCie was kept on for more than 20 hrs nothing is happening. The unit is set to "Big" and not "100 Safe" thus not RIAD is enabled. The rear LEDS are solid blue but the front one is solid red. Also the on/off button is not working, need to unplug the power to turn off.

You can use any brand or any size. It does not have to be a Lacie Brand Drive, but if you planning on using the RAID which makes an exact copy of one drive on the other drive in the server, you must pick two identical drives of the same brand and the same size. It can be any brand or size but both of the drives have to be identical. Otherwise, the RAID Will not work.

If you have any further questions, please let me know.

    During RAID Synchronization
    Front LED – solid red
    Rear LEDs – Te LED corresponding to the original
    disk will be blinking blue and the one being synchro-
    nized is blinking red
    Once both disks are synchronized, their correspond-
    ing rear LED and the front LED will be solid blue.

    Turn on the drive with the new hard drives and let it run for a few hours. I believe the drives are going through raid synchronization. If they don't start working after a few hours and the rear and front LEDS both don't turn blue, let me know, and I will continue to research your issue.

LaCie 2big Triple - I replaced one drive, but capacity is wrong

Most likely the problem you are encountering is due to the RAID mode the device is set in. Most RAID arrays utilize multiple drives of the same size, or with drives of differing size, they just use a portion of the largest that matches the smallest drive. When the device rebuilt the array it partitioned off a portion of the 4tb drive of the same size as the existing 500gb drive. If you want to use full capacity of both drives you would need to use JBOD mode, which just strings the disks together into a storage pool using all available space. This won't offer the data redundancy of RAID1 or speed boost of RAID0, but should allow using full space.

Backup any vital data before doing anything, then look for a switch on the back. Rather than RAID0 or 1 the options may be labelled Safe or Fast, but JBOD is usually still labelled JBOD, or sometimes Big. You can try just flipping the switch to JBOD and seeing if it rebuilds to use all space. If that doesn't work you may need to remove the 4tb drive, connect it to a different system and erase it to get rid of the 500gb partition, then with the Lacie set to JBOD reinstall the 4tb drive so it will add its full size to the array.

The safest option though would be to buy another 4tb drive, backup all data and install both 4tb drives with the device set to RAID1/Safe. You would only get 4tb of total storage, but it would mirror the data on both drives so if one fails the other will still have your data. With JBOD you won't have any auto-backup. If a drive fails the data on it will be lost.

Value of the memory capacitor on the PCB of the LACIE EDmini v2

If the voltage and the farads are higher than the original it won't make any difference what you put in. They are not much greater than 47uf, if you think it's 10uf than put anything above that in. It will really depends on the physical size of the replacement. Get one they same size as the one that's gone and you can't really go wrong.

Backup slow

You don't specify whether previously on your USB it was the same lacie external or whether it was a different external drive. It sounds like you were using a different external drive, most likely a single drive.
You've specified that you've got your lacie setup in raid 5. Raid 5 gives a very good read spead and a good redundancy for incase a drive fails, however it's write speed is very very slow.
It will be much slower than a single drive on USB for writing to it (i.e. backups), but you should see a huge performance boost in reading from the drive than your previous usb.
If you need it to be faster, you would be better suited looking at configuring it for one of the following raid setups:
Raid 0: striping (not recommended for backups) - data is split over all drives, however if 1 drive fails you lose all data.
Raid 10: striping + mirror . half the drives are striped (like above), but the other half mirror the striping half so if one drive fails there's a backup of it. You only get half the disk space though, so if you have 4 x 1Tb drives, then you'll only get 2Tb of space.

I have the same issue

Win XP will not be able to recognize whole 3TB storage drive. You need to use some kind of 3rd party utility and then partition it and format as well.. AS a note win xp size is limited up to 80-100 GB.

Exactly same problem

check your network for conflicts, check power supply, fan and nic card, if your sure it's not the the drives inside the drive case, I have had 4 of these fail on me @work with different issues power supply nic card and both drives 4 units did the same thing and they were under warranty so when I got it back, I sold them and bought The Seagate BlackArmor NAS 420. no problems with them as of yet. Lacie get hot and components get hot and fail because there is not enough air flow I think.

Blue light on Lacie Drive blinks.


I have seen the power adapters go out on the Lacie external drives and that causes the light to flash. You can check the voltages coming out of the adapter with a multimeter if you have one available. The voltages should be 5 and 12 volts. If you don't get that then the adapter is bad, you can contact Lacie about a replacement adapter or get a generic case and swap your drive to it. If you need a replacement case I have a link to more information about the one we use inshop at

I hope this helps, If so please rate my solution.

Replaced with new drives but can't see the unit in my network (MAC) nor ping to it. But when I put in the old drives I can see the unit in my (MAC) network.

I've just discovered this as well and you need to set the original drives to safe100, wait until the mirroring finishes and then replace one drive at a time. The factory drives hold the operating system for the unit. I unwittingly wiped both old drives before figuring this out.

How to recover data from lacie etherdisk when it does not keep a network conntection.

I'll have to look into it a little more but off the top of my head I would say that the nic may be going bad or some other component of the etherdisk. You can try opening it up and putting the hard drive into an enclosure and connecting it to a pc via usb to get the data, you can also then share the usb drive and use it over the network, however removing the hard drive may void any warranty you may have. If the hard drive is in fact bad then you should be able to replace it and then continue to use the device. I'll get back to you when I get more info about the device.

Replacing a failed Drive

Well, that may happen.. oh did you see that flying pig..
But seriously it will in all probability be fine.
Actually if ya wanna get picky, you usually replace RAID drives in Pairs.
But ya should be OK. That is moreor less to "Cover" themselves.
As long as the drive ya gonna replace is the same specs as the one ya replacing.. I say ya good to go.
