Hello boczek,

We understand that you're having detection issues with your Intel® SSD 535 Series on the http://http// Intel® Desktop Board DX79SI.

Your SSD uses a power management feature called DevSleep, which allows your operating system to place the drive into an extreme low power state. To exit this state, you motherboard then needs to signal the drive awake. Some legacy motherboards do not support this feature, resulting in the drive not being detected.

Windows® 10 for example, has a feature called "fast startup." Fast startup helps your system boot faster by placing it in hybrid sleep mode rather than shutting it down completely. If this feature is enabled the only time your computer will shutdown completely is during a restart.

The main step that we normally recommend to resolve this issue is a BIOS update. However, since your board has been discontinued, I was unable to confirm if the latest BIOS will help:

- Latest BIOS for the Intel® Desktop Board DX79SI, version 0650.

If after updating your BIOS the issue continues we can recommend making the following changes to your operating system:

1. If you're using Windows® 10, disable fast startup (this was called fast boot in Windows* 8.1): http://https// The Pros and Cons of Windows 10's "Fast Startup" Mode - by (scroll down to the "how to enable" section).

2. Disable fast boot in your BIOS. 3. Change power settings so that SSD never idles: Control Panel > Power Options > Change plan settings > Change advanced power settings > Hard disk > Turn off hard disk after > Change "On battery" and "Plugged in" to 0 (setting this to zero is the same as "never").4. Apply our special firmware to disable DevSleep altogether:
