My SSD Hard Disk freezes intermittently.

I got a SanDisk Extreme 240 Gb disk.

I have installed it in a Toshiba Portege R500 laptop, then I installed Win7 x86.

It worked with no problems since the SSD had firmware R112 installed. Since I updated the SSD firmware to R201 it started freezing as described in this thread.

I tried enabling/disabling HIPM and DIPM but it did not work.

Now I’m writing hoping that someone at Sandisk would understand that there are issues with their new firmware that make the SSD useless.

I hope that someone could tell me if there is a way to downgrade the SSD firmware to the previous R112.

Thanks
