Need your help - LaCie 2big Network hard drive 

Given the device's resemblance to the HAL9000, the error code it's flashing is probably something along the lines of "I'm sorry Florence, I'm afraid I can't do that." 😛 Jokes aside, the only network drives I'm familiar with are from Synology, so unfortunately I can't be of much help there.

I have a couple 4big drives, as a DAS. That means 1 or more drives are failing. You'll need to find how the drive is set up (is it RAID'ing) need to replace them both and download a factory TFTP recovery app to reinstall the NAS software. Be sure you find a drive that is of a similar model and vintage of firmware; because if you get a brand new off the store shelf of a SATA drive, the Lacie may reject it. EDIT: I missed the final third with you logging in. Something else is wrong.

Here's what I can think of: 1. Maybe there is a CMOS / clock battery inside that's dead and it's causing issues (I've seen some wierd things happen in computers, like not being able to access the BIOS, freezing at startup, etc) 2. Maybe try removing both drives and booting it that way 3. Remove both drives and put in a single known working drive to see if it changes

With devices of that age, in a dusty environment like server racks, it often happens that the buttons don't work properly anymore. I would open it and swap the pushbutton and then try again. If it's a weird proprietary button, just make your own using 2 solid core wires crossing each other and touching when you press. I literally repaired an OEM PC power button for someone like this LMAO.

I have one and Seagate stopped supporting the hardware and software for the device a year or two. For practical purposes it is a large paperweight.

From what I can tell these only have half a meg of flash onboard so if you wipe the drives you probably end up with a factory reset. But then you'd need to restore and who knows if you can do that?

Pretty sure those have a TTL serial interface (3.3V) on the pcb for serial console access. IIR though, the pins are not right next to each other on a nice neat single header (or pads for a header).

Sorry if you said it and I missed it, But did you try logging in with admin for both the user and password? To reset it should just pull the power and hold the button then plug it in and keep holding until it turns red don't press and release at first.

You followed all these steps to try and get the 'factory reset' to take effect? ... Press and hold down the front LED button. Without releasing the front button, turn the product on using the power switch on the rear of the product. Keep the front button pressed until the front LED becomes solid red, then release it. The LED will blink red. Within five seconds, press the front button once to confirm the reset. The front LED will blink blue for several seconds. The front LED will blink red/blue during a system reset. The LaCie 2big NAS is ready when it reboots and the front LED is static blue.

The only issue I've ever had with LaCie external drives; I have two One being a 1TB Big Disk FW800 version. It had similiar but not quite the same issues. SO this may be completely unrelated but have you checked the external power supply (if it hs an external one) that it came with. Mine was genuine; but seemss to be a fail point; after I'd done some googling.

the device documentation talks about some kind of recovery mode using LaCie Network Assistant (LNA). did you tried that?
