The OCZ Vertex SSD I've got seems to have issues with firmware. I upgraded it to v1.5 awhile back and it seems to have caused some file corruption issues. v1.3 was completely okay for me even though there were alledgely issues with that as well but v1.5 has many complaints on the OCZ forum.

The support from the forum isn't particularly amazing since the answer is basically wipe it clean and if that fixes it then great otherwise RMA it. That is the "have you tried rebooting?" equivalent it seems from OCZ.

Downgrading is a pain since you have to jumper some pins on the drive and install v1.1 which wipes it clean again. The formatting isn't a big deal for me as I have to do it anyway to reinstall the OS but having to open the laptop to get at the pins is going to be annoying...
