Remounting filesystem in read-only

Hi,

I have serious problem with my laptop. In last two weeks filesystem remounted itself in read only mode four times during usual usage.

last dmesg:

fsck doesn't show any errors.
I was searching for solution, but all similar problems was hw related (bad cable/disk).  Any change this is only sw related?

Quite possibly broken hardware. I'd make backups ASAP :-S

Re: Remounting filesystem in read-only

If you believe recent statistics OCZ has up to OCZ 7.03% return rates in the SSD market.
Source: http://www.overclockers.com/forums/show … p?t=712600
6.37% OCZ Agility 3 60 GB
I hope you can copy your data to a secure place.

Edit: 15.58% OCZ Vertex 2 Series SSD 240 GB : Really?
