Use the following steps:
- Disable Intel® Smart Response Technology in Intel® Rapid Storage Technology’s acceleration tab, and then “Reset disk to available”.
- Run a Secure Erase on the drive. The SSD manufacturer usually provides a software tool for this purpose.
- Enable Intel® Smart Response Technology. Chipset Software — Intel® Smart Response Technology User Guide
You may use the Intel® SSD Toolbox for Intel® SSD products.

You can also run the Secure Erase from Linux* running from a bootable USB drive or live CD/DVD.
Thanks Joe. My IRST control panel has "Status", "Manage", and "Preferences" buttons but nothing regarding acceleration and no options anywhere. Is is possible that Lenovo has crippled it to prevent users from getting into trouble?
I should mention that my SATA options in BIOS do not include RAID, only AHCI and compatible. The IRST manual only seems to specify that it be set to RAID.
I found this thread which describes my problem closely: IdeaPad Y580 and RapidDrive - Lenovo Community . There are a few others.
Could it be that I am not actually running RST, but instead running "Rapid Drive"? If that is the case, according to that thread the only way I can fix this problem is by re-installing the system.
It is possible your system supports a different acceleration/caching software solution. I recommend asking Lenovo* for the appropriate software your system supports; it may also be listed in their download page for your model.
