I just had to RMA my 120GB Vertex 3.. was having loads of issues - iaStor0 errors, failing drivers and services, antivirus not working, system freezes, and the System Event Viewer log filled with errors and critical errors..
Tried Windows Clean Install on a normal HDD (taking the SSD out) and everything worked fine, including my BitDefender! Should have a replacement soon - will post some benchies![]()
The iaStor error could have been due to your motherboard and not you drive. I had to RMA my P8P67 Pro for that reason. I'm glad I didn't update my firmware as I've had no problems since installing my V3 - such a good drive.
