Part Numbers:

We have discovered a technical issue affecting our SV100S2 drive. Kingston strongly recommends that a firmware update be applied to all SV100S2 drives to prevent possible failure. As with any firmware update, we recommend that you back up your data prior to applying the firmware revision.

Please check your SSDNow for the following number: "120504" (see illustration for location).

If you DO NOT have 120504 on your SSDNow as shown in the illustration, then you need to perform the Firmware Update. If you have 120504 on your SSDNow, then your drive already has the firmware update from the factory, and you DO NOT have to perform this Firmware Update.
