Question Problematic Neutron XT turned 2MB

Hi guys, TLDR first:

A Neutron XT 480 GB had been causing OS freezing sometimes and then bricked into a 2 MB drive, not recognized by OS now. Had compatibility issues with HDD.

Long story:
I had been using two HDD drives for a long time until I got my hands on a Neutron XT 480 GB SSD. At first the system with Neutron and a 1 TB WD HDD installed together wouldn't start. It would if I disconnected the 1 TB HDD.
I though it was a SATA controller issue. My motherboard has two controllers at once. It has a SATA 2 and a SATA 3 controllers. But juggling with the drives and controllers didn't help.
I bought a PCI-E SATA 3 controller, tried connecting the disks to three different controlles, but to no avail.
I then tried to disable AHCI in BIOS setup and it worked.

I installed an authentic Windows 10 copy on the SSD and it worked fine for several days. I noticed that once in 4-6 days OS freezed and wouldn't boot after reset unless I cut the power for a while and let the MB condensers wear off. That power cycle always helped and the PC would boot. I thought it was the compatibility issue aftershocks and didn't really care.

Since I had already had issues with SSDs previously I didn't place any crucial data on that Neutron and that was a good move because after another freeze and power cycle it wouldn't boot. Only 1 controller out of 3 (SATA 3 Marvell SE9123 on the MB) now recognizes it and it says the disk has 2 MB capacity. The SSD doesn't show up in any disk utilities though. So I guess those freezes were signs of SSD failure.

I've heard it might be a firmware issue and there are ways of bringing the disk back to life. But everyone is concerned about saving the data so nobody says how exactly one can re-flash the disk. Those can be only rumors though.

wat do?

UPDATE: It shows as a 2 MB drive in Ubuntu and in hdparm.
-i flag returns:

But I am not familiar with this utility so I dont' know if this info can help or not.

Can you run SSD toolbox and see if you can update the firmware?
Have you tried secure erasing the SSD?

I would also contact customer service, explain how you got your drive and issue and see if they can replace the drive for you.

Hi, Toasted!
The drive is not visible in the Toolbox. Actually, it is not visible in any disk tool under Windows OS.

I have tried secure erasing in Parted Magic live CD, but it didn't help. I mean, the procedure reported to have been completed successfully, but nothing had actually changed.

I guess I have to try RMA.
