LaCie 2Big triple disk drive replacement

You didn't provide details on what mode you were running or if this worked before and this is a sudden event. The manual doesn't appear to cover this situation of one blinking red light: https://www.lacie.com/download/manual/UM_2big_Quadra_EC_EN.pdf
but I found a YouTube video that may be helpful to you:

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.

Hello,
your drive can be used with any D2 or Big Disk power supply as well as some LaCie Porsche power supplies (you need to make sure the connector is the same).
Searching for LaCie Power supply on eBay will give you a few hits that match your needs.
Regards,

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.

LED Indicators - LaCie 2big Network
The LED indicators above the drive bays and the front LED indicate drive status and activity.
During Startup

• Front LED – blinks red/blue until both disks are powered on, then turns solid blue.
• Rear LEDs – blinks red/blue until corresponding disk is powered on, then turns solid blue.

NOTE: If the device is not able to initiate the boot process following disk startup, the front is solid red.
During Bootup

• Front LED – solid blue
• Rear LEDs – solid blue

NOTE: If a disk is failing, both the disk’s corresponding rear LED and the front LED will be solid red.
During RAID Synchronization

• Front LED – solid red
• Rear LEDs – The LED corresponding to the original disk will be blinking blue and the one being synchronized is blinking red
• Once both disks are synchronized, their corresponding rear LED and the front LED will be solid blue.

Sounds like you may have been unlucky in starting the reformatting software for the drive. Goto the following link to check out the documentation for the product:

The power adapter must be faulty, replace it with a new one.

It's all about the interfaces.
The Quadra has four interfaces: • eSATA • FW 400 • FW 800 • USB 2.0
The triple has all but the eSATA interface listed above.
For doing video work you want a big drive with a fast interface. If you have eSATA available then that's the fastest. If you don't then you're just as well off to go with the triple interface. The FW 800 would be the next fastest, then the USB 2.0, then the FW 400.
Because of the way that data is transferred I believe that when doing video work you would be best served by the FW 400 instead of the USB 2.0 even though the USB is faster I don't believe it is a full duplex communication so the FW 400 is actually better for video.

Hey Al,
The internal Drive is a standard 3.5 inch IDE 7200RPM unit. you can indeed upgrade this to a 1TB drive as long as it's IDE wether 2.5 or 3.5. Luckily when Lacie was originally offering these drives you could get these in 1TB, so that won't be an issue.

Solved! After 17 hours of blinking, the status of the 3 leds is now to fixed blue. You just have to be patient...
Note that I had only put 1GB of data on the drive. I expect that the resynchronization time is not proportionnal to the amount of data on the disk!
