Intel has hurridly withdrawn the firmware put in line day before yesterday, intended for the SSD Postville that brought the management of the Trim and also a performances increase for the model 160 GB. Many people found that after this update their disk ceased to function. The difficulty seems to arise under Windows 7. After the update, the system while restarting detects a problem on the SSD and refuses to continue to launch out and is blocked.
Intel will have to race against the clock to isolate and regulate the problem as fast as possible.
