SSD suddenly empty?

Hi!

I have a Corsair Force 120GB that I bought for something like 2,5 years ago. I been happy using it since, but yesterday the computer with that disk wouldn't boot any more. OK, fine, I connected it to another computer using an USB-adapter.
That computer couldn't recognize any partitions at all - I've been there before, but this time it was different.
Using following commands:

jake:tmp zyber$ sudo dd if=/dev/disk4 count=5000000 | hexdump 
Password:
0000000 48 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
0000010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

jake:tmp zyber$

The meaning of this is that the first 2,5 GB of the disk is empty. Zero. Nada, No data fragments at all. So I let it go thru the whole disk, and the whole disk is zeroed out.

I then contaced Corsair thru their webpage, but they only told me some crap about updating drivers in my computer.

I still have the receipt of the buy.

Cheers,
Zyber
