Use Crosh to test SSD

Use the steps in this section to test the health of the SSD storage drives on your Chromebook or Chromebox using crosh.

NOTE: 

The crosh diagnostic tool for testing storage health does not work on devices with eMMC memory.

1. Power on the Chromebook or Chromebox and sign in to your account.
2. Close any open programs or tabs.
3. Press the ctrl + alt + t keys to open crosh.
   Crosh opens in a new browser tab.
4. Type storage_test_1 into crosh, and then press enter.
5. A screen displays the storage health test results.
   Check for failure messages that might indicate failing hardware.
   If your Chrome device features eMMC storage, the storage test does not run.
6. Repeat the test using the command storage_test_2, and check for failure messages.
7. Close the tab to exit crosh.
