I was using OCZ Vertex 2 SSD in the past, when (possibly due to a firmware bug) it just wouldn&#x27;t appear on the SATA bus anymore and had an error LED lit up.
I RMA-d the drive, and they said they have to reflash the firmware, but doing so would also loose all data because it would erase the AES key. (I never configured any encryption on the drive, but apparently it does use it by default).<p>Needless to say I didn&#x27;t buy OCZ again, but I&#x27;m not sure if this is a general problem with SSDs or just Sandforce controllers.
